Hello,
This issue
is related to a power problem in as much as the TV turns off on it's
own. I think the TV has developed a power problem.
The problem is consistent with overheating on the power supply board of the TV.
The
power supply board of the TV has few capacitors and IC. If any of these
IC's gets short or become weak, it can cause the TV to turn off on it's
own.
When current passes from electric outlet to the power
supply board of TV. The current also goes to the weak/faulty part, then
the current stops or slow and the board overheats and TV shuts off on
it's own.
This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
This
is a common problem faced by many other users too. To solve this issue,
check the power supply board and read it with a meter and continuity
tester, in order to detect the faulty part and replace the faulty part
on the board which is short due to which power supply board.
Sony specifically uses GM1 Board. In other words, Sony power supply board is called "GM1 board"
It's a bit technical job but yes its not at all a costly repair to do or get it done by the technician.
You
can buy this part at any Fry's or Radioshack store or you can order
them online at vendors like "mcmelectronics.com"(look for electrolytic
capacitors). After replacing these capacitor (capacitors) most likely
the normal operation will be restored. Or you can buy a refurbished
complete GM1 power board from shopjimmy.com to save you some stress.
If
this task is too technical for you, you can call a family or friend who
has the ability to assist you (two heads are better than one).
