Nick's TV - thanks for the offer. Have not 100% locked in travel route and timing yet, when we get it pinned down in next week or so, will let you know if we will for sure be coming though Tucson.

Re: Sony XBR49X900E no picture
Nick's TV - thanks for the feedback. The main board was sold as new and unused, not at take out, bought from Gearbrokers Kansas City. Maybe I can bring the whole tv and all the boards, in a few weeks I am driving through Tucson on the way to Phoenix. Can put in in the original box and stick it in the bay under the motor home.
Do remember that during the initial failure - the TV came on and worked normally for from up to 30 seconds or a minute until it went into the everthing works but no picture just dark grayish blue glow mode that...Leave a comment:

Re: Sony XBR49X900E no picture
Did the hard reset as part of putting in the new main board. Also repeated it tonight. No change. Only difference Before & After the first reset was before the tv worked and you could switch channels and hear different stations sound. The picture or lack thereof actually was the same Before & After the resets.
Of course after putting in the new main board and doing the reset it no longer goes to the point where the TV is operational without picture it now goes to the point where it's trying to do the set up routine which I can't see...Leave a comment:

Re: Sony XBR49X900E no picture
Put in the new Tcon board (the third including the original) and still no change. Did not check voltage of power supply, but have tried two different supplies and same appearance of screen. Will check voltage in next few days, I presume spec is the nominal voltage printed on the supply?Leave a comment:

Re: Sony XBR49X900E no picture
Finally got some time to work on the TV. jjanssen7 suggested "Have you tried disconnecting the ribbons between the tcon and the panel one at a time (with the TV off of course) and then turning it on?"
I did this and the TV screen behaves exactly the same as described earlier (no picture, slight glow appears in lower left with volume key press on remote, diffuse glow appears and moves around with up and down arrow presses on remote) with one or both ribbons between the tcon and the panel disconnected. Makes no difference in...Leave a comment:

Re: Sony XBR49X900E no picture
So maybe I originally had a bad main board, it knocked out the tcon too. Then I bought another tcon put it in the set leaving in the original bad main board. The replacement tcon was knocked out by the original bad main board. Then I bought a new main board, put it in and the set still would not work because the replacement tcon board was knocked out by the original bad main board. So next step is to get another tcon board and put it in the set with the new main board?Leave a comment:

Re: Sony XBR49X900E no picture
Thanks for the reply. I did initially have trouble getting the update to "take" and renamed the file as you suggested based on something I saw in a you tube video, maybe yours. The update then ran and appears to have taken as the TV boots up to the point where the Sony set up music plays. Just can not see a picture. As to whether the ever ribbon and cable is functional, I unhooked and reseated them all.
The thing that stands out is no matter what I have done I get the same appearance of the screen. It goes from the "pure...Leave a comment:

Sony XBR49X900E no picture
Have a Sony XBR49X900E. Tree in yard was hit by lightning. Next day TV would not come on. Found external power supply was dead. Got a new one. TV worked fine. Few days later watching TV and picture went dark. Sound still OK, channels change OK, but can't see any picture. Still has some dark blue gray uniform glow to entire screen. Turn off TV. Next day turn on TV works normal for minute or so, then same thing, sound OK, functions OK but screen suddenly goes dark.
Do note that when TV comes on and see dim blue/gray glow if press volume control on remote, the lower left corner... -
