I was thinking a fuse, but don't think it would come on at all?????
I did read somewhere else, someone had a similar problem. Although I can't seem to remember where and what the fix was
(sorry! old age lol)....
As soon as it comes to me I will post.
The 6.5 flashes are not a code, it will flash fully 6 or 7 times (2-7 flashes are code. and will flash repeatedly with a 3sec. pause between the code flashes and will give 1 code at a time, until fixed that is, if more then 1 problem).
I believe the problem is on the d-board (could be wrong though). I believe it has to do with the high voltage/fly-back transformer. But don't take my word for it
... If you can get one off CL (same model or very similar). Then it may be worth hanging onto for spare parts (if you got room to keep it).
Good Luck with it or in your search for replacement. Sorry, couldn't be more help. And sometimes it just isn't worth it (for the fact that unless you can find a repair tech to look at and/or fix for a good price. I say it may not be worth the guess that any certain part or board could be the problem
And it certainly isn't worth the money and MAY NOT be the fix).
I really hated saying that. I really don't like to hear that any of these TVs went to landfill!!!!
