Dead KDf 60xbr950; 6 blinking red lights. I spent hours on research & would like 2nd opinions, please.

I've got a 3 1/2 yr old 60" KDF 60XBR950 which suddenly just died. The blinking light sequence says it's an internal problem. I am not a tech by any means, but am handy and willing to try a few simple procedures to save huge repair bills and a weeks of waiting. In any event, I researched a bit and downloaded a service manual which tells me as follows: "+B OVP error 6 times +17V is not supplied.(G1 board)" The board is cheap enough ($45 plus s/h) and even to my untrained eye looks easy enough to replace. A few screws and careful removal, matching and reinstallation of wires and the replacement should, at least in theory, be done. Whether or not this solves the problem is whole differnent matter...... The threads I saw here point to various possible issues such as the board itself or even the optical block (ouch!). If this is the issue I'll be speaking to Sony and/or just buying a new one. I am willing to swap what appears to be an easily reached component, but am hopefully smart enough to stay away from buried or delicate components. The G1 board seems to be neither. I pulled the back cover and could see it there right in front of me. Here are my questions: Is this a worthwhile to at least try replacing the G1 board? My realistic worst case scanario is that I waste $60 in parts/shipping. Well, OK, the total worst case is that I drop the TV and smash it in a million pieces, but I'm trying to be at least somewhat realistic. Any suggestions/hints/warnings or other ideas? Thanks to all in advance. Much appreciated

Thank you for spending the time to help. Much appreciated. Unfortunately, the problem is far more severe. Seems the "Q box" died--a $900 repair, which Sony will not assist me with.

Do I fix it or buy a new one? Hmmmm........

Thanks. Even better-- Sony is giving me a new 60" XBR2 (usual price: around $3K) for the cost of repairs, or $800. This should work!

Not the board, there is a thermal fuse under the lamp housing that has opened up, you need to order an upgrade thermal fuse link that will mount to the Lightengine side of the lamp housing, the clips are there, there is no sensor there.

My Opinion is Buy a new one, a 55" Sony LCD runs under $1500

KDF-70BXR950 HAS CODE 6, I have lamp housing and optical unit block removed and see no such thermal fuse. there is a thermal fuse on the schematic that connects to the A board but there is no illustrated location. Anybody have a clue?

Fuse is on TOP of lamp housing: two wires leading to the fuse shoved into a small cavity. there is no replacement available so I twisted the leads together. this was the solution, NOT using the 'shotgun approach' of replacing the board favored by so many other 'experts'. kudos to les for knowing his stuff.
