Bent Image Where is the convergance amplifier IC located on my panasonic PT-53WX42. How much is it and what adjustments need to be made. I dont want to pay someone to fix it when I am perfectly capable. Please help

your convergence ic is going bad. remove front and adjust the level of blue.

Blue background lines with colors otherwise OK may be a loose or dirty blur drive potentiometer on small circuit board behind front grille and beneath front imerboard cover. These are hot-glued in place from factory but may be the cause f the problem. They're VERY sensitive.

If you have bowed blue lines instead of properly aligned colors, you probably have a blown convergence amplifier IC. These boards are no longer available so yours will have to be repaired. Some shops repair them but many send them out for 6-10 weeks. Fairly expensive too considering the amplifier chips are about $35 each (x2).

It can be fixed, I have someone coming out tomorrow. You you stay turned, I will post an update as to the fix tomorrow.

Need to replace the convergence amps and any 2.2 ohm resistors in the return. That unit takes two STK392-110 Sanyo amps - but for greater reliability use STK392-150's and get them, from some place like ACME to be insured their not chineese knock-offs..

convergence IC bad

Your TV most likely has a Convergence Chip Failure ( common problem )

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.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Change both STK convergence IC's for reliability. They amplify/control both horiz and vertical. re-align after replacement.Locate them on the largest heat sink in your set!

if you can remove the rear panel assy. look for the convergence ic's they start with stk--- and you got the part number you need a source panasonic is 814 source and the number on the ic's stk 390 ----/

You need new convergence amps, and if you dont know what you are doing in the tech menu you could ruing the set. Call a Repairman Delicate soldering is required.

Excelent description,whats happening is your set starts to show a blue convergence problem and is only correctable by replacing the blue convergence amplifier IC,the set has 3,one for each color,not all of them develope problems but they all develope loose conections,after the IC has been replaced there are adjustments to do.If you are familiar with tv service this information will give a place to start but if you are not too familar be safe and call a servicer to help you.Lets US know how it goes.
