AKAI LCT2715 Power Supply Removal

Intro: AKAI LCT2715 Power Supply Removal

How to disassemble your AKAI LCT2715 to access the Power Supply

Step 1:

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

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:

If you would like to have your power supply professionally repaired/reconditioned contact me. I offer this service at a reasonable price and I have very quick turn around times so you can get you TV back to working order fast!

    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.

    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

    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

    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.

    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.

    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!

    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?
