Problem for Hitachi 50UX58B 50 in. Rear Projection Television
Wont power up
By juliancope on Aug 14, 2007
after being unplugged for awhile during power up all lights on board light up including red one ,while red light on front flash and all goes dead . you must un plug or remove fuse to repeat these symptoms.tv has been left on for long periods of time. while powering up (plugging in)i can push the power button quickly and the lights on the main board will stay lit until power button is pressed again and its instantly off.seems like a common problem but no shops in my town will even look at it instantly dismissing it as convergence chips over the phone , suggesting purchase of new tv any help would be appreciated.

- I have a similar problem. When the tv (Hitachi Ultravision -52" rear projection) is left unplugged for a period of time, the picture and sound comes back. It worked for several hours a day for a couple weeks then the picture changes to a "cigar shape" and finally the picture and sound fails. If I again leave it unplugged for a while the same happens, picture and sound for a short period...again. What could cause this and would it be easy to repair by a layman or should it be left to a professional. Would it be costly to repair? The TV is about 8 years old.- weiner2837Best Solution

I have seen that symptom many times. Most likely, the little blue capacitor next to the horizontal output transistor has shorted and popped the main B+ fuse. This is very common in those Hitachi projection sets. These parts should be replaced by a tech familiar with Hitachi projection sets.

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,
