In that case there's a problem in your picture tube, you need a technician to check for it.

Kp 61HS30 TV Had the tv since 2002. been a great tv. Just recently it started making a noise when you turn it on. Noise fades away after about 10 seconds. Noise kind of sounds like a dvd player trying...


If you locate the audio board, check for dried up electrolytic capacitors and dry joints around the output IC itself.
That should fix your fault.

Picture has blue shadow/trail? sony KP-53HS10


This sounds like a bad blue CRT (cathode ray tube) The repair on this is a major job. Beyond the tube replacement it would then require some convergence alignment and possibly some setup on the other related service adj. such as geometry. You may want to get an estimate from a reputable local repair company.

Sony kp-53hs10 picture is cloudy and 3 colors at bottom of screen red blue and green


Look at attached photo--if it is what you have you have a convergence problem.

The KP-53HS10 uses two of the STK-392-020 convergence chips.

Both will need to be replaced and the set adjusted--parts cost on ebay is less than 20 dollars--repair consists of two things--getting at the parts and then replacing them--chips are soldered in so you need to be able to un solder them and solder the new ones in.

No picture and tv automatically turns off


Good day.

You are getting an intermittent performance for your unit. One reason for this might be with the loose contacts on the high voltage section of your unit. Have it resoldered.

Sony 27"TV will not turn on


The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer

No picture on a Sony KV-32V65 TV


AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking.
