If your SONY will not start and it is blinking the 6 or 7 blink code you can fix this by installing a new IC at location IC6501 and IC8002. You use the same IC's at both locations and they can be purchased on eBay for about $20. for a package of 4. the #s on the IC are: MCZ3001D and 0542D - they control the horizonal deflection circuit. Good luck.... OR you can pitch the TV because as I believe SONY's are junk. They are made in Tijuana Mexico.

MHC-DP900D HAD SAME PROBLEM- PROTECT, PUSH POWER. TRACED CAUSE TO AMP. DC PROTECTION CIRCUIT ON AMPLIFIER BOARD. ACTUAL FAULT WAS A SHORT CIRCUIT OF THE AMP. IC LEFT CHANNEL OUPUTS (STK412-030 PINS 10 & 11)
EXCESSIVE SOLDER APPLIED DURING MANUFACTURE HAD PROBABLY BEEN HEATED UP ENOUGH DURING USAGE TO BRIDGE THE PINS. CURRENTLY USING THE UNIT WITH RIGHT CHANNEL ONLY UNTIL I PURCHASE A NEW IC. BYPASSED DC PROTECTION FOR LEFT CHANNEL BY ISOLATING INPUT TO DC DETECT TRANSISTOR.
This is what I could find, it looks like it will need serviceing unless you can do it yourself, it can be deadly if you don't know exactly what you are doing.
Thanks for the fixya rating, hope this helps

Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell (nh@totalise.co.uk)
