One morning I turned on my TV and no picture; sound is fine. I bought a new lamp but that did not fix it. I paid a Sony repair man to come by and he says something like the "Q" board is bad. a new board is ~ $471.50 with a trade in. Does all this make sense? the TV is 20 months old and will cost me ~$800 to fix as he wants $300 to R&R the board? Can I R&R this myself?

i see a couple possibilites. im not going to rule out a bad lamp. the lamp does come on sometimes. i have seen faulty lamps display this sympton. since it gives no error codes (blinks) and then does not shutdown. i feel this is a deeper cuircit board problem that a tech might need to troubleshoot. how long has it been since lamp been replaced
Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!
