Toni, you`ll need a tv tech for this problem, spark gaps need to be cleaned, crt sockets need to be cleaned and crt pins on all 3 crt`s need to be sanded, this is a common issue with this model set, good luck, BMW Rider

Any Hitachi remote made over the last 15 years should work the basic functions of this model--Take a look on Ebay. Did the original get lost or stop working?

I have the same problem. I took the back cover off of the TV and blew all of the dust out and the TV started working again. But this only lasted 2 days. Now the TV is dark again.

Tv suddenly started being blurry with red double images real bad in top half of screen. its a hitachi ultrascan hd about 10 yrs old.

You need the convergence ICs replaced they are soldered in so its very technical , a repair shop will charge between $230 and $400 to replace them. you can try the autofocus or manual adjustments, but probably need the ICs and possibly a few resistors too.
(2)STK392-110 or kit # X480293 comes with 2 ICs and some resistors

Hitachi 53" rear projection is losing its picture.

If you are not experiencing any shift in colors, it sounds like the power supply is failing since this will affect all three colors.

Ultrascan hitachi 43" hd tv

What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.
