6 lights according to the service manual is: LOW B ERROR B_12v IS NOT SUPPLIED (GT BOARD)


Check the connections to the boards, and if nothing seems obvious, you may need a repair person to replace this board...

    Read a bit more on this, apparently it could also be a blown thermal fuse.

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.

Won't power on


You still have power supply trouble, even after replacement of the board. Recheck the replacement work; could be something wrong there

I have a 4 year old Sony KDF-E42A10 television - the power/standby light blinks red 5 times, pauses, blinks red 5 times again, etc. I have replaced the lamp previously when the light was blinking red 3...


Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

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 Trinitron Wega Standby blinks & the TV won't turn on


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
