Sony KDF-E42A10

I've seen this diagnosis on the internet for the 5 blinking lights

5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.

the link i gave you had all

the link i gave you had all the parts of the board that you needed to test for that ammount of blinks,Q what ever numbers are probably transistors google testing transistors,the # after the Q is also the location on the board so find the numbers on the board and you find the part and you test it......

I have the 60" Sony Wega 3lcd

I have the 60" Sony Wega 3lcd,lately it just shuts off for 15-30 seconds,then it lights back and the sound comes back on.
I`ve already went thru the blinking lights and replaced the bulb about a year ago.This time there is no blinking lights or anything. Please help,Dave

From what i understand about

From what i understand about the 3lcd tv's theres a single lamp that shoots light into a filtering system then into its own LCD chip,sounds complicated.Ive never been inside one my self so i havent the faintest idea,but if your loosing all colors then i would assume it would have something to do with the lamp or main pwr to it.If your loosing sound and light theres a problem on the main pwr board,sounds like a circuit is getting hot and failing,cold blast of air will find it.

Was planning on pulling back,and blasting with air,incase dust has built up on something.
