Green Screen then off...8 blinks

My Sony (mfg November 2002) JUST started this about 2 weeks ago. Comes on normally, then after about 25 seconds it flashes light green and shuts itself off. I'm getting 8 blinks from the standby light. I'm wondering if this is an HV DC Block failure, or if it is the dreaded "flicker problem." TV has worked great until 2 weeks ago...any ideas for self repair??? Thanks

Re: Green Screen then off...8 blinks

According to service manual, 8 blinks is a high-voltage error. A link to the manual and a how-to guide for retrace lines is here:

My KDF-42WE655 will not turn on . The green start up light comes on and I can barely see the tv come on . After a few seconds the red light starts blinking and does not stop. The screen never comes on ....

Hello! When was the last time you replace lamp in your TV? If long time ago (2+ years) - replace the lamp. If red light blinks in sequence (example 4 flashes, pause, 4 flushes, pause and so on) - then I need to know how many flushes between pauses. It is an error code. If it blinks just constantly - it is a bad lamp. Regards. Russ.

The 8 blinks is pointing to a bad flyback transformer and may be common with this set. (We have one too.)
