My Symphonic WF2703 TV remote began working sporadically, then quit altogether; remote control is working for other components, just won't control TV at all. I isolated circuit RCV101, removed a small IR receiver transistor 342D0017, took it to my local TV repair place, they said they couldn't help. Got any ideas?
Here is my blog on the subject how to repair remote controls http://www.instructables.com/id/Repair-your-remote-controls/
To dignose if your remote control is faulty just point your digital camera towards your remote and push the buttons. If your remote works you should see light flashing on the LCD view finder of your camera.
Repairing the remotes can be succesful about 90% of the time unless the remote has been chewed by the family dog ?

An easy way to test for output on the remote controllers is to point them at a camera from a mobile phone. If you watch the camera picture whilst pressing buttons, the LED's will flash and show you the output. If you have dodgey buttons, it will show up as no LED flash. Hope that helps to decide where your fault is.
I thought this was a free website. It sounded like it. I didn't pay much for the TV, so if I have to pay to know where to get a remote control, I can just go out and get a new one and it won't be Symphonic. Thanks,...
