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.

    I will check that out tomorrow. I replaced one resistor bc it looked burned out and then it started looking bowed. Before I replaced that it was only 3d like.

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.

Tv turns on. There is a picture but it looks like your looking through a fish bowl. Bowes into the middle from both sides. It also looks 3D. Any Clue??

This is usually a convergence problem, although the bowing normally is from the top and bottom rather than from the sides. There may also be an issue with the pioncushion circuit that causes the bowing. Try the automatic convergence adjustment first. If that fails to resolve the problem, then resoldering the convergence ICs would be next followed by replacing the ICs should the resoldering fail.

If you wish to attempt the repair, please update this and confirm the model number to be VS-60607 and I'll provide additional details.

Thanks,
Dan

3d picture and looks like bow tie

Bad STK ICs replace both ICs will have part number on them STK392-110s if this is what you have upgrade to 150s! ICs are Big black ICs also ck 2.7 ohm resistors near ics.

RCA mm52100

Ok thanks for the info Now this is an indication of convergence issues(3d effect) the bowing issue idicates a complete loss of convergence power. which possible could be the convergence ic or the actual power feeding them. im feeling like it might be the ic overheating these get very hot. now the bad news. this is a set that is very difficult to work on. Rca has compiled a long list of problems with this set. getting to the chips is a chore. i cannot recommend repairing this set. I know no one likes to hear this.

there are several rca issued suggestions. the top one isChange C19542 on the Digital Convergence PCB from a 10uF 63WVDC capacitor (214698) to a
470uF, 25WVDC capacitor part number 214746.
Also change the 24V zener diode CR19720 (226446) on the Convergence Power Supply board to a
30V 500 milliwatt zener diode, part number 231211 this
but as i said this may or may not be the best solution

The Model# is 53UWX10ba - Colors off in upper left part of screen

The problem is with the convergence circuit. If you can solder, try resoldering the pins on the convrgence ICs. If that fails to resolve the problem, replace the ICs. These ICs will be large and black, attached to a heatsink and be marked STKxxx.

Update this with your progress.

multicolored 3d effect is a problem with what is known as convegence... ussally there are two large chips (ic) that blow. gennerally they have to be replaced mabe some fuses and resistors..

Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Convergance/bowing

most like tes thats all your going to have to replace + the silicon as if you dont thet wil not last as long as they should. Also you may have blow fuseable resistors next to the ICs make sure you check them as well.
