My sony is dying please help I got the 5 blink code akb circuit. It works sometimes then sometimes shuts down with sound blinks 5 times then turns back on. It seems to only happen when a bright comercial comes up turns bright then goes down. Where should i look to fix the problem inside the set. Embarassed

Weird stuff going on it will play normal then when a certain part of a comercial comes on it gets a little brighter then goes into akb blinking 5 times then when it blinks 3 or 4 sets of 5 times it restarts normal then when a comercial gets brighter or a tv show does it again. minnie thanks for youre help apreciate it.

A comercial does not get brighter on my TV or your TV but the sound is increased by 3DB they wants to hear the BS what you see is the result of your TV miss behaving period . the cuase can be the vco getting out of range, power supply . i put my money on the power supply
