The plasma is 3.5 years old, picture went black, no response except for sequence of 10 blinking lights, is it worth it to fix?
Talk to or email the mfr; they should be able to advise you.
Its not going to be worth fixing, but its up to you. A repair shop is going to be 300-600$.
Ten blinks indicates:- Sub 5v SOS / Main 3v SOS DG Board / DTV 9v SOS / Tuner Power SOS
Which usually means the power supply board has blown and possibly taken other boards out as well.
Sounds expensive to me.
