51PP9303H/17 convergence repair help

3d viewing. Red will not converge. Can you fill me in on the part #'s/location of the IC's and resistors that need replaced? I will be getting a schematic soon to assist me. Thanks!

I would change all convergence IC not just the one that holds the red. You will need the schematic to get the resistors location.

My magnavox HDTV model #51MP392H/17 the year on the back of the tv is 2004 the picture on the screen looks like its in 3D how can i fix it myself. I tried a new cable box it only worked for a few minutes...


The convergence ICs and resistors have failed. You will need to install a convergence repair kit. The Phillips DPTV305 chassis convergence repair kit is the correct one for your magnavox. Its available at www.tvrepairworld.com and the kit contains the 2 ICs and resistors and the CD with repair instructions.

Hitachi projection TV - video is in 3d rainbow


This sounds like a convergence circuit problem. Your set has two convergence IC chips (integrated circuit). One is for the red CRT, the other is for the blue CRT. This is a common issue with projection TVs. It is not a difficult repair if you have any experience with electronics and soldering. Both convergence ICs should be replaced at the same time. The part is IC (STK394-160E) and is available for around $36 or less. If you have a shop fix this they will likely charge $300-$400. If this information was helpful or if you would like to know how to do this repair in more detail post back on this thread. I would be happy to walk you through it.

Your symptom sounds like a intermitant or damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

What happens in the Panasonic set is that the convergence IC’s will short and cause the power supply to shut down from the overload of current. Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center.

Too much red!


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
