Hello,

Its the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
This will help.

When I turn on TV, it immediately turns itself off. Previously if I continued to turn it on it would eventually stay on, but now it will not stay on.


I had this problem with my JVC TV. Turns out that some gunk had built up in and around the power button itself. I took a toothpick and a cotton swab with alcohol and cleaned around and between the the power button. Hope it works for you too.

Hi, The TV is shutting down because there is an internal fault, there is more likely a panel that needs replacing or a few faulty components.

It's more than likely repairable.

If it's under warranty contact your dealer for repair or replacement.

Pioneer PDP435PG inadvertently reprogrammed by Casablanca remote.


Some ceiling fans have jumpers that can be moved to select a different frequency but you have to be sure both the remote and the fan receiver are set the same. Other than that, you may have to use some creative control. For example, I can turn on my TV by pointing the remote at the wall opposite the TV
