My 26" 1997 Sharp T.V. model #25H-M60 turns off by itself and won't turn back part of the time.


First thing if you are able is to unplug set and remove rear cover (lay set face down on a padded surface).

entire main board should be able to be seen or released so it slides out--take a very careful look at flyback and rest of board for any cracked or bad solder connections.

One bad connection (age) can cause this.

Samsung HL P6163W turning it self off after 15 min.


Do a factory reset to this set. If sleep timer function is set to 15 minutes, the set will turn OFF by itself after this time.

Grundig TV turns itself on


Remove power for a day and see if the processor resets. It seems to be only due to the timer as the TV can be triggered only from the internal timer to power ON.Try and reset all the timer settings , switch power off completely and it must cancel all settings.

So far you have done all you can and you have done everything right. The fact that the TV turned off by itself and then turned back on by itself suggests that one or more solder joints have come loose inside the set. A qualified tech should find this easy to fix, and Sony sets are always worth repairing, so it is now time to have the set serviced by a tech experienced in Sony standard sets.

TV turn off itself and won't turn on


Sounds almost like you have a voltage missing on the power supply board. if its a missing voltage a service manual and a multi meter should help ya find whats missing But a shop repair on a set like this could cost a bit as anything over 27" is a little costoly to fix these days. Only way to see is call and say to your self How old is the set? is it the set you really like do you wanna spend 150 to 225 to repair? it up to you. Good Luck
