TV will not turn off with remote or manually

the problem is,,its 12 years old,its a projection tv,and it hasnt found a home in a dumpster yet

Ur convergence is problem.U know how to solders?Tries these website for convergence kit.Tv repair World.com,Tv repair kits.

Make sure there is not a lock turned on. Hitachi loves to use locks.

The Convergence IC's have went out. This is normal for this TV after about 5 years or so. You will need 2 sanyo STK392-150 IC chips, and about 6 resistors to fix. The cost is about 50 US dollars if you do it yourself. If you are not good at soldering, don't try it. However if you are, and can read an ohmeter it will be no problem

I suspect the unit might need service. If it were only the remote, new batteries would, of course, be in order. But that part about the manual power button being ineffective suggests something else is affecting the set. Sorry.

Good Day;
If you don't hear the relay click suspect Q003. No power suspect Q912, Q914 & I901. Good Luck, big IRISH.

the convergance amplifier have failed there are two of them they need to be replaced. there may be some pico fuses and resistors also. convergance failure is the most common rear projection tv it makes the set appear blury.
