Question about RCA F32648 32" TV
My sister has this 2001 TV and she says it has a mind of its own.
Do you have any suggestions on what is wrong and is this something I can fix?
I am an electronics
technician who just happened have been given the same set as you
because it was giving the previous owner the same problem. Since I am
confident in my trade, I took the set and diagnosed noise in the remote
receivers input to the cpu.
Please understand that my set's specific problem was that the unit thought that it's remote was giving it false directions such as constantly opening up it's guide menu.
What believe is happening is that a capacitor( or something) wasn't working properly and was either not filtering the noise out or it was introducing noise into the data stream that controls the TV through your remote control.
My fix was to essentially cut out the entire remote control input to the TV. Since I have a directtv box to give me remote control, I don't care if the TV's remote works anyway.
The way I did this was to open up the unit and find the front I/O board were the buttons meet the switches for power,chaennel, volume, etc. On that board there is a plug with white wires and one black wire. The two wires to cut are the one next to the black wire and the one all the way at the other end of the black wire. These two wires are easy to splice back if you do not like the results of this procedure so that there is really no risk of damaging your set. If you wish to verify the proper wires to cut, they are the two wires that come from the IR receiver's side of the board YET DO NOT GO TO THE OTHER SIDE WITH THE BUTTONS! There is one wire that does indeed go to both sides.
This may not be a perfect solution but it is free. I hope that this will help someone out there.
