Introduction: Remote Control Update
I have a remote TV from our cable company that is about 10 yrs old. We also have a newer remote from the same company. I noticed that one is weak and you must aim the remote at the TV or cable box for it to work. The newer one seems to work a lot better.
I started think about it and figured out the Infrared LED was the problem. Being older they just did not have the output like todays ultrabrite LEDs. I went to Ebay and found these high power 5mm diameter (same as the one in my remote) for .$ 2.85 for 10, I ordered them.

You can see from the pictures my remote and the new IR, LED.
Step 1: The LED Replacement.
I opened the battery door and removed the batteries. Then, not seeing and screws I carefully pried the case open so i could get to the LED. Picture 1 above
All LEDs are marked + / - or anode and cathode. I is very important to know the LED has a flat spot in the lens. That marks the Cathode. My remote circuit board had markings on it. picture 2 above.
I used solder braid to remove the solder from the old LED as seen in picture 3 above.
Picture 4 shows the new LED soldered in and the old one on the table next to it.
Because LEDs emit the light in a cone pattern I decided to leave the new one a little longer so it would not be blocked by being recessed in the case. that can be seen by comparing the original and the new one in pic 2 and 4.
i carefully aligned the keypad and case a snapped it back together. The last picture shows it sticking out a little bit but not too far to get damaged.
I put batteries back in now i can even point it at the wall away from the TV and it works perfectly.
We have a be nice policy.
Please be positive and constructive.
