Hitachi ultravison 50 in HD TV w/o sound or video access

This T.V. more than likely has a bad lamp. I don't know the model number so look up on ebay for a lamp replacement by model number after you inspect it and find it to look cloudy or exploded.

Check the tv fan it is running?No than the fan require replacing.Yes,than the tv projection lamp life are ending require replacing.

try connecting in a new video input,,check connecting cables as well

you might need a new lamp, considering the age of the set, if there isn't any buzzing, constant clicking. You probably just need the lamp.

Sounds lamp in TV getting weaker and soon it will be replaced.
When dlp tv start showing darker picture then its time for new lamp to get back vivid picture.

ether the lamp needs to be replaced or you have a bad capasotor on your power board

While you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image.
Let me know what you see.

The satilite works. The TV won't turn on al all, teied everything.

if you are hearing a click and electrical statics when you try to turn it ON, the flyback of the tv is busted there are alot of reasons for that problem lighting is one so dont leave the cable screwed in if ever youre going out for a long time. you can have it replaced by a technician ( flyback). but it would cost you. and im not sure if you can find an orginal flyback considering its 10years old. there are replacement flybacks but quality would not be as good as the original one.
