Good day, papamotts;

Hitachi has LED’s, green ‘lights’ and a red light to determine what circuit may be the problem; after removing the back of TV, bottom only, plug TV back in and observe which LED’s come on …..BUT most important which LED’s don’t come on; locate and note number, EG; DP37 and etc.

Good luck, big IRISH. Ps let me know.

I have a 50ux22ba hitachi top and bottom of picture bow toward center of screen and the three colors will not align


You need a Degaussing and convergence done.

Over time, running the TV magnetizes the parts and the electron beams no longer 'shoot straight' ALL your symptoms are caused by magnetism in the metal parts of the TV.

A good tech (like me) can make it like new! Look in yellow pages for a BBB certified Hitichi Proj TV Repairman or ask your church to name one.

Good Luck!
They charge $30-150.00hr for this (depending on where you live)

I have a 1998 Hitachi 50UX57B that suddenly shut off and will not turn back on. Bought the set new, no problems until now. Red "power on" light comes on briefly after set has been unplugged for...


This set has a problem most likeyl within the power supply or the horizontal output transistor has failed. In either case, the set will not completely power up. If you can solder and wish to attempt this repair yourself, please update this. Since remote diagnosis with little symptoms like yours at the momenet is difficult at best, I'd suggest that you get a detailed repair estimate (should be less than $100). Post the results here and we should be able to walk you through the actual repair.

I Have a Hitachi Ultravision projetion TV Ned help to fix it.


This sounds like the solder joints on one of the convergence output IC's have cracked loose or the IC itself is defective and quitting when it warms up. The IC needs to be either resoldered or replaced.
