Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Convergence problem Hi all. I've had this 53" for 5 years and have loved it every day I've watched it. A week ago I turned it on and the magenta color didn't line up with the rest. I used the Magic Focus and it stopped part way thru and then a #4 shows up in the lower right corner. The extended warrentee just ran out and I just had it serviced (cleaned)in February. I would appreciate any help someone can give on what chip set I would need to fix this. Also, do I need to purchase the service manual set this back up? Thanks!

Re: convergence problem

I had the same problem sounds identical. My warranty was up in a couple weeks when this happened so they came out and fixed it. They replaced the red converter IC. However just recently the blue and green is acting up??? My warranty is up now so thats a bummer.

Have a Panasonic PT-47WX53 47. It's probably as old as when it came out. I've messed around with the convergence before but it was never un-fixable. Then a couple a days ago I came into the ro

yes and also possibly the low ohm resistors. You can get the PT53WX53 convergence kit which fits your model from which has the 2 ICs and associated resistors plus the CD with repair instructions.

Color shadowing on screen

I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

RCA 50" - Convergence problem and now "Popping" + no picture

The high pitch popping that you are hearing is arcing in the high voltage circuit. I would not suggest a repair on a set that is this old. Convergence repair plus a high voltage problem could run around $500-$600. But it is your call on the repair, I can only advise.

I hope this helps you.
Thanks for using FixYa

TV wont turn on, makes buzzing noise and shuts off

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.

yes its most likely the STK392-110 ICs change both at the same time. You can get replacements at the following link with free instalation instructions.

The leading cause of this type of failure is convergence.. Replace both convergence Ic's Stk392-110 and check all 2.2 ohm resistors in that circuit... This repair on this particular unit is fairly easy because the convergence amps are mounted in such a way to easily remove the left board for field servicing...
Have a great day!

Hi there, Check IC601, C603 for leakage, I601 and vertical pulse detector QN05 for poor convergence check RK42 for open circuit. Best regards, Arpi

The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
