G-board 12 0r 13 volt regulator .... this is a PLUG IN board... no sodering involved and very simple to replace.. i ordered a brand new complete g-board (for around $60 back then) unpluged the old one pluged in the new one in less than 5 minutes and the tv has been working without any problems of not turning on ever since.
check with see if they have the board on hand.
also check D6116 or D6301 is open (G board).

There is a problem with one or two of the diodes on the G board.

Sony Wega stanby light blinks 5 or 6 times

When a Sony TV flashes five times, that means that there is an AKB circuit fault.
Six blinks is also a fault related to video problems, and regards a fault concerning the digital board and the Jungle IC (the main CPU).

This means that there is something wrong with the video.
Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.

I have the Sony tv that blinks 9 times

My sony KP-51WS520 blinks 9 time and once in awhile will power on, but lately it does nothing at all. To replace the parts you can try I tried to replace one part hoping it would fix the problem, but just ordered part A1054157A based on a recommendation of a different comment posted on this web site.
