TV wont come back on.

Dad turned it off.

There is no picture or sound coming from it.

Power button just flashes.

Dad brought it to the tv shop and they said its the power supply. $135.00 to check it.

Another 400.00 to replace the power supply.

I do work on electronics. I repair Video Games and jukeboxes...

Tv's ar not My thing....I have repaired quite a few but figured I would ask an expert..And I dont want dad to spend another 400.00 seems whey to much. So He's on a loner Tv at the moment.

Thanks in advance!

Also light just steady flashes no codes so to speak

P.S Its 1 and a 1/2 years and out of warranty.
