I recently began having problems with my rca 32v432t television. It would cut off and on by itself. I solved this problem by removing the front panel on/off button (the remote works fine). Now after about 15 minutes or so, a small timer begins flashing in the upper left hand corner and it shuts off. I have checked the "off" timer status and it is "off" as is the status of the "on" timer. If anyone has any suggestions, I would greatly appreciate any help. Thanks.
First thing would be to make sure none of the other buttons on the TV switch panel are causing any problems, as I have see the switched become leaky with resistance between the contacts and cause all sorts of weird problems. Try to get to the control board with all of the switches and see if you can disconnect it without disconnection the remote sensor. I have also seen a remote sensotr cause all sorts of weird problems. If by disconnectiing the switch panel, and this problem persist? Disconnect the remote sensor and see if the problem goes away. Good Luck, and let us know how you made out with this TV repair.
