Question about Hitachi 50SBX78B 50" Rear Projection Television

2 Answers

Nothing on my TV

The other night I was watching and I heard a pop and now there is nothing. I was told it might be the projection bulb? How do you get to this bulb to see if it needs replacing?

    I have a 10 year old Hitachi 50SBX78B projection TV. I heard a pop the set went blank. Unplugged the power pulled the back off the set and checked the 5A fuse, it was OK. Plugged the power back in the green lights on the curcuit board went on for a short time then off again. everything is off no lights, no anything.

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,

This set has CRT guns. 3 of them. No bulb.
Check and see on this site what others have suggested for your problem.

Without seeing it I'd say main AC fuse

It seems lamp/ bulb popped again, check lamp inside tv.
If tv does not show red blinking light then it would be lamp that knocked off, replace lamp in tv to fix its problem, please buy Sony original lamp for good picture in tv.

Nothing happens. power on,can hear click


I had the same problem, but I saw the events leading to it. I was watching TV, went to help the wife, heard a pop, came back to find the TV off. Turned it on, heard the same click you described. I believe you need a new bulb. Mine lasted around 2 years of heavy use. Bought two on ebay. Make sure to consult your manual for the particulars on the bulb.

You need to replace the lamp in this set. The "pop" you heard was the lamp popping.

Will not turn on


Does the set make any sounds. DOes the front green led light or flash when you try to turn it on.. if not then it could be as simple as a fuse, if it does flash then it can be many problems

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

No Power


Your set is going into high voltage shut down. Might have been the high voltage transformer that has gone bad.
