Question about Sony KP-46WT510 46" Rear Projection HDTV
Hi my Sony Sony KP-46WT510 tv will not turn on. When you push the button the light blinks 8 times and the resets and blinks 8 times and so on but never turns on. Can anyone give me an idea what may be wrong with it and what to expect from the repair guy. Thanks for any help
Can you tell from looking at the HVB that its bad?
Burn marks on them ect...
Mine looks like nothing is wrong with it.

The High Voltage Block - part# 8-598-955-32 was an easy fix. It will take you about 30 minutes. You'll need a phillips screwdriver and possibly a small pair of pliers to remove a connecter (at least I did). While I did not take pics or write down step by step, here are some general instructions. Make sure that the tv is unplugged. Unscrew the panel. The screws are all the same size so don't worry about matching holes. Disconnect the wires to where they are connect. The thicker red ones that enter the HVB themselves are done in a "twist and pull" method. You will need to use this same method when hooking up the new one. There is also a small black cylinder piece of plastic around one of the wires. Make sure that you remove it from the old HVB and place it on the new one. You should be done with the grunt work. Place the cover back on. Check out this site on how to clear the diagnostic codes or else the light may keep blinking... http://www.iwaynet.net/~nesda/SonyBlink.html

8 blinks means that the High Voltage Block is shorted - part# 8-598-955-32 (about $80)
