Thank you for posting your question on Just Answer! I will be happy to help you with this problem. Can you please give us some more information so I can better answer your questions.
-When it stops working, do the buttons on the tv itself work?
-How old is the unit?
Please give me this information and I will be happy to assist you further.
The TV was made September 2003. The buttons on the TV does work. Actually it is a circle on top of the TV that you can move from side to side to change the channels or the volume.
The on/off button is on the botton of the TV right of the green light when the TV is on and right of another eye. When I cover that eye the remote will work.
Are you using the origianl Philips remote or a cable/satellite remote?
Thats the original.
Ok what I want to do is just check the remote to be sure...next time it stops working I want you to do a test for me. Do you have a digital camera or a phone with a camera? I want you to point the remote at the camera like you are taking a picture of the end of it, then press a button and look at the camera, do you see a white light emitting from the end?
You either have a micro or a bad system control circuit though, problem here is that repairing something like this will run $200 or more depending on what exactly is found. If you know how to use a meter and solder I can assist you with the repair, if not though you would need a repairman.
