Sony LCD Model KF-60WE610 lamp was replaced and then it shortly after stopped turning on. Blinks Green 6 times then Red 6 times Please help!

For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

I have a SONY KF-WE50 rear projection tv, a few weeks ago it started to turn the pic and sound off while the green light was flashing around 30 times. After the light finished flashing both the picture and...

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Picture went out and red light flashes 6 times then stops a while and blinks 6 more times

Something is not sending the proper signal telling the tv to start up. Most likley is the thermal fuse on the optical block. Could also be a bad fan or even a bad lamp. Good luck

Sony Wega KF-42E200A Projection Bulb

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.

SONY GRAND WEGA KF-50WE610 can't turn on TV screen.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Hello Failrlane.
You have a bad thermal fuse. You must remove the back cover in order to fix this unit. The thermal fuse can be found near the lamp housing. part number for kit: A-1137-954-A
