    The tv used to turn off after 15 minutes of viewing, now you can turn the tv on and it will turn off immediately.

SOURCE: PROJECTION TV HITACHI ULTRAVISION COLOR CONVERGENCE PROBLEM

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

Good Day;
Try this:

Symptom: All Front LED indicators are flashing in sequence: Power-->Temp-->Lamp-->Power......continuously
Cause: Replace Lamp . This symptom may happen all the time or it may be intermittent. It is normal if it occurrs from time to time, See OG under TV Front Indicators explanation notes.
Good Luck, big IRISH.

Hitachi has had problems with their light engines. Very expensive. Contact Hitachi as they may give you consideration even if this is out of warranty.

Hitachi HD big screen won't turn on. It was on, turned itself off and now won't power back up


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

for poor convergence check RK42 for open circuit.

I have a hitachi ultravision 60sx11ka


cory, your losing the high voltage, could be bad solder joints in the horizontal circuit, ie; driver transformer, horizontal output transistor, or the transistor and associated capacitors have finally failed. If you keep trying and it will eventually start then it`s definitely bad solder and that`s a cheap fix from any local tech.
