Question about Sony Grand WEGA KDF-70XBR950 70" Rear Projection HDTV

1 Answer

Hi, I have a KDF-70XBR950. Had a lightning storm coming so heres what I did. The TV was on and had been running for a few hours and I was nervous we'd get a power surge so I shut off the tv and unplugged it. Obviously not considering the fan needed to keep running to cool off the internals. Anyway now I have the power/standbye led blinking 6 times and no tv. I tried parts changing a little bit and changed out the lamp and the cover for the lamp (had problems and fixxed myself before). But this stuff didnt help. Tried leaving tv unplugged all nite, then plugged in and let sit half the day. Still no picture and 6 blinks of the led. I'm figuring its a circuitboard, what say you. If it is can I change something out like this myself?

    Thanks Jee. Can you give me model number of g1 board and where would you get one from? I'm gonna give it a whirl on replacement myself. How hard could it be to swap out? Thanks so much Tom

    Required board part number is as follows:
    A1302365A .... G1 BOARD, COMPLETE
    and available in Sony Part Store for $45
    Put part number in above link search box to find out price info.
    Board replacement is easy as I mentioned before, unplug connectors on old board, unscrew it and take it out, put new board, tight its screws, plug connectors. Thats it.

KDF-70XBR950 70 in. Rear Projection HDTV Television My TV took a power surge and I?m getting the 3 blinking lights, I read online that it?s probably my g3 board. I check the lamp and the cover but...

3 times red standby blinking light indicates Lamp Cover is not attached securely or Lamp has not been fixed properly inside tv. Make sure lamp and lamp cover are securely attached in tv.
I do not think G3 board is bad because 3 times blinking error is related with lamp cover that engages micro switch inside tv.
Let me know your findings to provide you more helpful info.

Sanyo DSs31820 dead after lightning storm. Is there a master reset?

A lightning storm will destroy a TV in many cases. I have repaired very few, with this problem. I would certainly find a new TV, if this is the case for sure. Thanks for asking!

You need a new projection lamp.......(XL-2100 replacement DLP lamp)..... go to this web site to get the lamp you need for your TV model KDF-70XBR950 70inch----
------ This web site shows you how to install it yourself. ----    --------- I strongly suggest that you get a SONY manufactured replacement lamp NOT a cheaper lamp from another manufacturer... it costs about $200.
