Question about Mitsubishi VS-50607 50" Rear Projection Television

1 Answer

I just replaced the two convergence ICs in my Hitachi 53UWX10BA projection TV and it looks very good in the middle of the screen top to bottom, but as you go out both right and left the convergence gets worse. I also changed RK42,46,50,54,58,and 62 as they all seemed to be out of tollarance a little with RK50 being open. At the very right and left sides of the screen it looks like the red is off about 1/8 or 1/4 of an inch. I tried Magic Focus and it didn't help. Do I need to get an original remote and do a manual convergance adjustment? When you are looking at the screen the red ghost is on the inside toward the middle on both the right and left . Thanks for any help with this.

Yes, it sounds to me like it only needs touch up in the tecnician convergence menu. Which you get into by pushing the service only switch after the set is on and then using an original Hitachi remote control to do the adjustments.

I replaced the ics on my 53uwx10ba and now the top and bottom of my screen is bowed and it is still 3d like, what else could it be?


Take a good look at the dozen or so small resistors around the chips; most will be 1.2 , 1.5, 1.7 ohm and usually (not all the time) the culprit will be discolored in the middle.

These if good should read like a fuse if tested---no reading means gone.

Hitachi projection tv 53uwx10ba - the Convergence ICs were replaced. When the PDKP bridge between convergence board and 2nd board is plugged in, it makes a noise. Kept that unplugged, the picture is...


Did set have this problem before you replaced the STKS?

I know these sets very well. If problem is different in any way from before you replaced chips.......double check all soldering or one of the new chips may be defective.

The more you tell me the better I can help.

DOUBLE IMAGE ON SCREEN. tOP OF PICTURE LOOK LIKE A


That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

Hitachi 53uwx10ba turns on & off when off red flashing light/clic


Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

Replace the conv ICs. Sometimes it's just the soldering involved, DK on Hit. But bottom line it's usually the conv ICs. They work very hard in there.

I would change both ICs STK392-110 and also the 3.3ohm 1 watt resistors and the 1.8 ohm 1 watt you would need 2 of each resistor. Then your convergence would be new again. You can get replacement ICs and resistors at the following link with free shipping and free instalation instructions with pictures.
