Question about Hitachi 50SBX78B 50" Rear Projection Television
I have a Hitachi rear projection tv model #60SBX78B and it recently stopped working. The red power button lights up indicating that the power is on but there is nothing else happening. There are also some green lights on the electrical boards that are lit up and stay on. I have checked the fuse and it is good, but other than that I'm not sure what to look for. Any suggestions would be appreciated.
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,

The green led or lights on the board indicate some of the power supplies are working. The key is do you see any come on and then go out. this would indicate which part of the power supply is failing. also there are fuses in the set that do not look like your standard glass fuse. WARNING television generate lethal voltages that will hurt you. extreme care should be used.
