The usual cause of this is the sensing IC (there are 2 of them) on the power supply board. Sony usually recommends pulling the board and returning it to them for service.

MY SONY TV MODEL # KF42-WE610 IS SOUND IS COMING ON BUT NO PICTURE


If you turn it on and the, Power/Standby green light blinks slow 6 times; then it becomes a red fast blink 6 times, pause, then continues to blink red fast 6 times, again and again. this means when it's blinking 6 times is indication of electrical circuitry malfunction. The Television will need service.

Sony kp-51ws520 when turned on just has standby light flashing . the rest is all dead, no picture or voice.


Standby flashing light shows that tv got some internal problem. How many times standby light is flashing is info that provide info about what section of tv got problem.
Count standby light blinks and let me know, there would be 3 seconds long pause in blinks so count pause to pause.

My sony 50" wega just quit. No picture , no sound , no nothing ?


Hi,
If you see standby red light blinking on Tv front with 3 seconds interval then count its blinks from pause to pause and let me know, its an error code.
And if TV does not even show standby light then check fuse in power supply that would be blew off for some reason, replace it.
Still problem? let me know with exact model number of your Sony TV.
Thanks.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
