My Sony KP-51WS520 flashes 5 times, pauses, flashes 5 times, continues this pattern constantly. Could someone please help me with troubleshooting this code?

For the KP51WS520, 5 blinks, pause, 5 blinks, etc. of the red standby light means "White Balance Failure" and the probable cause locations listed are as follows:

1. Video OUT (IC9101, IC9201, IC9301) is faulty (CR, CG, CB board)
2. CRT drive (IC452) is faulty (A board)
3. G2 is improperly adjusted

These are starting points for a qualified service technician. That set was introduced in 7/2004. The real problem could be a defective picture tube. However, I would check out the CR, CG, CB boards before I jumped to that conclusion. These are the boards on the end of the neck of each picture tube with the socket that the picture tube is plugged into.

Personally, I would get a new LCD TV rather than attempt to repair this set.

BTW, you really should have initiated a new thread instead of tacking a post onto a thread with a different subject.
