Question about Hitachi 50SBX78B 50" Rear Projection Television
My power went off too. If I unplug the unit then plug it back in I see green lights on the circuit boards for about 15 seconds and the power light is on in front then it all goes off again.
If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address.
Here are the symptoms...
Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.
Hope this helps,

Well it could lot's of problem, first I would suspect bad convergence it's, you will have to insulate what circuit is shutting the unit down, could be over current, over voltage, difflection, convergence, bad power supply, no power (fuse), cold solder joint, when there is no difflection the system (CPU) will turn off the unit to proteck the crt's.
I would first start by syspecting the convergence section shutting down the unit.
