This tv was bought in 2002. I think it is a 2001 tv. Just won't turn back on.

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

for poor convergence check RK42 for open circuit.

Older big screen hitachi w/pip tube tv and has blue lines across the screen turn off on it own sometimes.

It could be time to retire the TV.
The blue almost horizontal lines are probably a fault in the flyback blanking and the fact that it will turn itself off is likely due to a poor solder joint on a circuit board inside.

The tv just randomly turns off by itself

Check to see how many times it blinks when turning off and then look for the codes for Sony tv blinks. this will tell you what's wrong. This set is notorious for Shorted tubes.

Good Day, richardyoung;

Lack of vertical reflection? Does this happen on all channels? Can you change channels and the picture size changes? Are you receiving a HD signal? Have you tried changing the format?

I hate to ask you all these questions but I need to understand your concern completely. If you answered some of questions above yes / no; your TV might be okay. But try them.

Good Luck, big IRISH.

TV wont stay on

Sounds like a short somewhere in there. I see old pre-HD big screen sets going for well under $200 on my local craigslist, so look there for a good replacement, because the repair will cost more.

Or fork over about $500 for a good used HD projection set.
