Hitachi ultravision reset converg - Hitachi 53UDX10B 53" Rear Projection Television

If the convergence is so far out that you cannot adjust with your customer access menu then You will probably need the convergence ICs replaced & possibly a fuse or resistor or 2. Then a complete convergence will be necessary & I HIGHLY recommend having a professional technician perform this task.

sounds like the convergence circuit has decided to quit working..  hitachi uses convergence output i.c.'s for this in the circuit.  one is probably bad.  suggest replacing both though..

Convergence has failed. $250 - 300 let a trained tech. do it for you.

I believe it is either interference or a convergence issue. To fix an issue with convergence try to find a convergence setting in the menu. If thatr doesn't work try to clean your projection lenses with a q-tip and alcohol.
Good Luck.

could be shoted convergence ICs

You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.

Possible convergence problem

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

for poor convergence check RK42 for open circuit.
