Yes.... u must adjust the screen voltage going to picture tube....located on the CRT module>>>little board connected directly to picture tube (take back off TV and you will see ) play around with screen control on the CRT module......can be adjusted at times to keep from losing picture!!! tube is bad...i know sure looks good when showing a picture....TRY adjusting screen voltage ( YES while TV is ON>>>CAREFULL ) gl
Most likely on a trinitron tube if it is dark is the high voltage capacitor has blown. This is the device that feed the 30,000 or so volts to charge the tube, it attaches at the back with a clip and ****** and a single cable coming from it.
You can check easily if it is definately that as you will notice if you power the tv on and off once or twice if you get that static charge feel from the screen, if there is none there then almost certainly that is the problem.
a picture that blinks in & out every few seconds then it could be a bad tube. I know the older models the picture would flash in and out with snow etc. that was a tuner problem. haven't worked on very many sony wega's, maybe another tech here has a better ans.
Sorry to take so long to get to you. Most sony Tuve TV's are pretty good performers for colour. If you are into that sort of thing, so can be worthwhile fixing. If it has power supply problems, may cost you up to $200 to fix. Rule of thumb, if repairs are more than half the replacement cost, it is uneconomic to repair.
When I turn on the TV I hear the click sound and the TV powers up. Immediatly the red (standby) light begins to flash 6 times on and off. this happenes only in the morning, but after 5:00PM when youturn on the TV as if nothing is wrong.
IT SOUNDS LIKE THE VERTICAL I.C. NEEDS SOLDERING. WHEN IT LOOSES THE PICTURE DOES IT HAVE ERROR CODE 2 ? THE RED LED BLINKING 2 THEN 2 THEN 2. THAT IS LOSS OF VERTICAL. IF YOU SMACK THE SIDE OF THE SET.(NOT TO HARD) WITH OPEN PALM ON LOWER BACK IF THE PICTURE COMES BACK IT IS THE VERTICAL IC THAT NEEDS TO BEE SOLDERED. DON.
My Sony FD Trinitron TV did samething, started flashing, then eventually went completely black with volume. I got on internet searched found a solution, i tried it, it worked. unplug tv, remove all screws, remove back. towards bottom right theres a transmitter with a couple of knobs, we plugged tv in and moved knobs around and it worked. Also was extremally dusty, we used computer duster for a better connection. hope it helps you
