Hi,
The screen on my KV-30HS510 is dark and the standby light is blinking 6 times repeatedly. Does anyone have any idea what it is and how to fix it?
Thanks in advance!
Gregg

Welcome to Agoraquest! For the KV30HS510, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:
1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)
This is the starting point for a qualified service technician.

Thanks for that information. I was hoping to fix this myself rather than go thru a tech. Do you have any more information that might help me further troubleshoot this? I've never taken one of these apart but I do have access to volt meters, soldering equipment etc.

Unfortunately, you need electronics troubleshooting experience to proceed. The service manual might help, but it doesn't tell you how to troubleshoot. For the service manual, go to http://www.agoraquest.com/manual_request.php.

Many Sony CRT power up problems are due to a failure of an 18 pin MCZ3001D IC. These ICs cost about $6 each and some desoldering and soldering is required to replace them. Search this forum for "MCZ3001D" for a ton of info.
Check out this thread where a KV-30HS510 was repaired with an MCZ3001D replacement:
