Good repair Suranga. As some people has told above, I use my cell phone with the camera function to watch if IR LED is working properly, you can see it flashing in your cell's Display any time you press a key.

You can also use an AM radio tuned the bottom part of the dial which will produce a buzzing noise when a RC button is pressed.

Hi All
I strip the remote and remove the battery- 's, put all plastic covers/ housing and pcb in basin and wash with a nail brush hot water and normal hand soap, Scrub the housing PCB and rubber function pads until clean
Now check for bad solder joints. Dry with a hair dryer if in a hurry, reassemble, clean remote

Yes that is another way to check IR remote signals Robert. I also know that when you use a modern CCD camera with a high shutter time you even can check if all tube luminescence lights have the same cos phi power factor.

In reply to Chad Jessup.

Chad, this happened once to my own remote control. The joints became dry/broken due to the external physical exposure of the IR LED. As it must be in front of the remote control, in order to point its emmission to the TV set, the LED was subject to mechanical stresses due to handling (the fingers applying pressure on the component). As time went on, this handling has imposed a continuous swing on the IR LED. All this effort was naturally concentrated on the points the LED is soldered. The rest of this history is easy to conclude...

Good job! I have done repairs of remote many times. Dry joints as well as the failure of crystal were the major complaints, added to the customer dropping, children playing with it and spoiling it etc.

I also would like to know how it was so obvious to you that dry joints were present. Frankly the pics don't make that clear.
Thanks

Hi Albert,
I use my camera in my cell phone or my other camera to check them. A while back, one of my nephews washed his remote with the laundry. After I dried it out and cleaned it up, it worked fine. The batteries were ruined though.
