Try aligning them using the yoke control rings.
sometimes the alignment is so far out that you have to adjust the magnet rings instead.

I have a hitachi 53fdx01b projection tv. The colors are shifted and droop downward. the cross hairs don't move when I try the convergence adjustment. Will new chips fix the problem?


If trying to adjust the convergence doesn't work, then is the convergence ICs that are defective. I would suggest to inspect all the solder joints on the ICs and resistors for possible cold solder joints. If everything looks good then replace both ICs and also measure resistors that are connected to the convergence ICs.
Let me know if you require further assistance.

When adjusting the convergence, ended up with a concave screen, then it smoked. Is this a power supply, or worse? Is there any advice that you could give me on this...


Thats usually indicating the ICs have failed. Usually with that model its best to replace the board rather than try replacing the individual components as ther are several 3.9 ohm resistors that will need to be checked and possibly replaced along with both ICs. www.tvcircuitboards.com should have the replacement board for your model if you need one.

Don't have remote is there another way to line up colors I've already changed the convergence chips but not the resistors


Chances are the new ICs have failed since the 6.8 ohm resistors werent changed a phillips will almost always blow one or two of the 6.8 ohm resistors and if new ICs are installed without replaceing the resistors the new ICs are usually destroyed by the blown resistors. You will need the original remote or authorized replacement to adjust the convergence properly.

JVC AV56wp74 convergence. Resistor before ICs?


It's recommended to replace all the defective parts first because if you only replace the defective resistor, it might burnt again if the convergence IC is shorted internally. I would also suggest to measure the other low value resistors with multimeter.

Problems with convergence


the convergence Ics have failed. You can get the repair kit for your model which has both ICs and the 12 feed resistors plus step by step instructions on how to do the repair. Heres a link to the repair kit for your model.

Red and green double vision


This is a convergence problem that is either poor solder connections on the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are ptentially dangerous high voltages present even when unplugged, you can fix this yourself.

Please let me know if you wish to attempt the repair and I'll supply additional details and instructions.

Sony KP-51WS500 Rear Projection TV colors are distorted.


Here are some of the most common symptoms and example photos of a convergence problem

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

Here is a quick test....

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

Try to adjust the red and then the blue 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergence


If you cannot align, the ICs probably need to be replaced. You can check the input on feedback resistors in front of the ICs with an ohm meter. Some resistors may be bad causing your problem. Usually you would need to replace the ICs and bad resistors and do a full re-alignment to fix.

Panasonic ICs


On your model its usually will not blow the resistors unless the set has shutdown with 3 blink error. But if your set is still working except with bad convergence you should be ok with just getting new STK392-110 ICs , but change both convergence ICs.
