How to disassemble your AKAI LCT2715 to access the Power Supply

Step 1:

Picture of

You are going to need a Phillips ( X ) Screwdriver for this proceedure.

The first thing you will want to do is find a suitable location to disassemble the TV. Try to find somewhere with plenty of space to work and preferably somewhere you will not have any hazards such as static (like carpet)

Lay the TV Flat on its face (picture side down) and remove the 4 screws from the back of the TV holding the base on.

Next you will want to process to remove the screws around the back cover. There are 12 screws you will need to remove (refer to picture for locations).

Carfully remove the back panel of the TV. It may snag on the coaxial connector so be careful.

Step 2:

Once you have the back off of the TV you can see the Main board and power supply covers.

You will now need to remove the left (right side from the back) speaker cover to allow access to two of the screws holding the Power Supply Cover in place. This is easy and pretty straight forward and has 8 screws around the perimeter.

Once you have the speaker cover off you should be able to access the screws on the side and you will also want to remove the other screws from around the sides of the cover. Some TV's I have worked on only had 6 where others had 7 or 8. Just make sure to remove all of the screws before trying to remove the cover.

Once you have the cover removed you will see the Power supply. Remove the wiring harnesses from the power supply board. You will have 4 cables at the top of the power supply and one main power input at the bottom. The main power input may have some glue securing it in place. Simply cut this with a knife or pull it loose.

Once you have the cables off of the power supply you can remove it from the TV via the screws on the 4 corners. Be careful not to damage anything as you remove these screws.

Thats it. You now have the Power Supply removed from the TV and ready to pack and ship.

I suggest placing the power supply in bubble wrap (preferably anti static) and placing it in a box of packing peanuts or some other thick cushioning media.

Step 3: Example of Power Supply in Need of Reconditioning

Picture of Example of Power Supply in Need of Reconditioning

Here is a power supply that is in need of repair/reconditioning. As you can see in this case the power supply capacitor array on the power output side have become bulged and are starting to leak. This is one cause for the power supply to be unstable and unable to provide appropriate power to the LCD.

The following pictures illustrate the bulging/leaking capacitors as well as the capacitors removed and new capacitors installed.

Step 4:

Does anyone know if Twizted is still offering his services since this is a very old site. 2701td with ? Power supply trouble. Regards DJW

Were you able to get any info. about Twizted TV repair services?

Thanks for the info. Does the solid orange light indicate a power supply issue or ? Based on what I read elsewhere, the new caps I used were not the same voltage as the originals in the case of the 16V and 25V units (all the replacements were 35V.) Is it possible that this may be the problem? As part of the further troubleshooting, I removed the other cover on the back of the TV and found two swollen caps there as well (there were only two large caps on that board.) Is this potentially part of the problem? Finally, what is your current price on repairing this power supply (in case I hit a dead end here)?

Hi Twisted. I did the removal and replaced all but 3 capacitors on the power supply board (bought out two radio shacks otherwise they would all be new) but it's still not working. It is different now than when I started though. Before the repair, the red light flashed intermittently when the switch on the bottom of the TV was turned on and the standby button had no effect. Now the red light is on solid but when the 'standby' button is pushed it turns green for about 2 minutes, then turns orange. One interesting note: this TV has always made a high pitched whine when powered up but turned off. It is once again making that 'familiar' sound (but still not working.) Any ideas? What does the solid orange light mean? I have only seen references to 'flashing orange' on the forums. Any help would be greatly appreciated.

Twizted (author)hpinfo2012-11-26

Depending on what capacitors you did not replace it could be that you still have bad (dirty) power going to the controller which is causing it to not operate normally. Also, it is possible that the capacitors you purchased were old and had been there for some time. Old capacitors can dry out as they have an electrolytic fluid in them. Also, if they were not quality capacitors they may still cause issues due to high ESR (Equivalency Series Resistance).

This instructable was very helpful in diagnosing the problem with my Akai TV. Even though I have a degree in electrical engineering, I decided that finding the right capacitors, replacing them, and then facigthe possibility of a bad transistor would be a long and laborious process for me. So I removed the board, shipped to Twisted, he repaired it for the price he quoted, sent it back promptly professionally wrapped, and I reinstalled it and all is well. Thanks for the great service!

Vernon, I have an AKAI PDP50006H that needs to have the power supply repaired. Are you able to repair this model as well? If so, can you email me with information on how I can mail the part to you and approximately what the cost will be? Thank you

West Guy (author)2010-02-14

Vernon, I sent you my power supply for the AKAI months ago prior to your move. You promised to quickly let me know right after that...I am very concerned you have forgotten me.

Please let me know where we stand with this.

Thanks. Al

Twizted (author)West Guy2010-03-01

Hmmm This is odd. I am pretty sure you power supply was shipped out right before our move but I will investigate this and let you know ASAP.

jermaljermetrax (author)Twizted2011-02-25

Hey, could i send in my power supply for you to repair it?

West Guy (author)Twizted2010-03-29

Vernon, it's been a month since you said you were checking to see what you have done with my power supply. Overall it has been since Nov. with no return. This is not a resonable time frame in spite of your move. Please return my power supply so that I can send it elsewhere. You promised a turn around in a brief time initially. I need to know what the deal is here pronto.

I have a Akai LCT2701TD with a bad PSU. Could you give me a cost on repairing this unit? My e-mail ; antontyberman@yahoo.com

onemanarmy41 (author)2010-07-22

hey your instructions are a1 and simple to follow , now if you could help me with my power supply that would be tops, thanks

staminaboy (author)2009-10-26

Great instructions! I got my Akai LCD2715 as a hand me down with the condition of "fix it and it's yours."  Twisted's instructions had my set up and running in less than a day for less than $30 (most of which went toward a new soldering iron).  Thanks much!

krishnalc (author)2009-02-10

I have an Akai LCD2717 that did not work for about a year. I tried to get estimates to fix it but was getting estimates of $400 to $500 dollars. When I found this site I thought I would give it a try to see if the power supply was in fact the problem with the TV. I followed these instructions which were very detailed (they did not miss a single screw), and was able to have the power supply out in about 15 minutes. The board looked like it was described with the power supply capacitor array on the power output side have become bulged and are starting to leak like described in the step 3. I contacted Twizted to get the details about having the power supply repaired. He got back to me very quickly. He repaired the power supply the same day he received it and shipped it back to me the next day. The TV has worked perfectly since I put it back in. The entire process was efficient, fast and professional. I would recommend Twizted services to anyone!
Thank you for everything!

Hi Twizted; Same problem with a LCT3201AD and need to rebuild the E7802-005008 supply. I can do it myself but thought you might want to sell a repair kit with the caps. Will that work?

Twizted (author)cliff.jacobs2009-04-14

I have actually been thinking about offering repair kits for PSU's with failed capacitors. Only problem you might run into is not all power supplies just need caps they may need a transistor, transformer etc... But, if you can tell me what caps you need I can put together a kit for you if I have the parts in stock. Just keep in mind that it may not be just caps.

cliff.jacobs (author)Twizted2009-05-31

The TV finally would not turn on so I popped out the power supply. Not the same one as in this post but had similar bulging caps. Replaced 3; 1000pf caps with a bit higher working voltage and the thing works like new. Thanks for the tip.

aleisen (author)2009-07-31

Hi I'am a TV repairman and I am working on a AKAI LCT301TD TV that has a defective MEGMEET MLT186 power supply. No 12v or 24v only 5v. I read on the internet on many such failures of this board . AKAI is of no help as well as their service manual. Does anyone know what goes bad in these power supplys, common troubles etc ? Thanks Al

markg123 (author)2009-07-12

i have a 32' Magnavox that i need to change the power supply on, can i just use a power supply from a 24" tv or do i need to order a specific power supply? thanks for any info!

Twizted (author)markg1232009-07-12

It is most likely that you will need to order the power supply for your specific TV as most TV's use very different power supplies. There are manufacturers who use the same power supply for multiple models of TV but this is likely not the case for a difference from a 32" to 24"

cmsursa (author)Twizted2009-07-15

I have taken my power supply out . Please send me your address and I will send the power supply to you for repair. Do you require a money order and how much is it for? Thanks, Chris

Theoden (author)2009-07-03

Please send me an email address or contact situation so that I can see about getting my power supply repaired. Thanks.

jgoodbar (author)2009-06-30

Hey there, I have a buddy that is giving me this TV because it doesnt work and he said it was the PSU. What do I need to do once I get it removed so I can get it to you.

Twizted (author)jgoodbar2009-06-30

I've sent you a private message with instructions on where to send the unit. I look forward to hearing back from you. -Twizted

Brucered (author)2009-04-02

I know this is a little off the subject but I also have an Akai Model# LCT3285TA that has power supply problems as well. Can you repair this power supply on this one as well? If so how much? Any help would be greatly appreciated! Thanks!

leviludwig (author)2009-03-17

Hi, I work at a bowling center and we have two akai lct2715 tv's with the same problem. One of them has 14 bulged or leaking capacitors and the other we haven't taken apart yet.. How can I get in contact with you to send the power supplies to you?

Twizted (author)leviludwig2009-03-17

Hello, I have replied to your other message. Thanks.

Par4 (author)2009-03-15

My Akai LCT2715 television gave a sizzling sound before it went out. Now it flashes a red light and the screen does not power up. I did some research to find out how many other has the same problem. I took this TV to be repaired to many places and I was told they are unable to physically fix or repair it. It seems no one does repair anymore. One person offer to buy the part on E-bay for $388.00, he will install it and charge me labor plus the cost of the part. Another person said he will send it to the manufacture to be fixed and maybe the part will be cover under a warranty. I don't think the manufacture cares about this product/part anymore, they went bankrupt.
While browsing the web I stumble upon “Twizted”, I read the instruction on removing the power supply. It is very simply, detailed and straight forward. I am not a technical person, but his instruction made me feel like one. I had the part out within 10 minutes.
I contacted Twizted and he gave me instruction on how to send it to him and within 1 week, the part was back and installed. The television works excellent. I am very glad I took this chance and put my trust in Twizted. I will recommend everyone whom is having this problem, to stop shopping around for a good repair deal and put your trust in Twizted. He did the job for us and at a fair price. He not only fixes the TV, he put the smiles back on my kid’s faces. They now have their TV again.
Thank you Twizted, Dude You Rock!
