Horizontal grey lines on TV

I have a PT-56WXF95 and the convergence went out. That was fixed but now I have light grey horizontal lines on the TV. It is most noticable on normal tv and light backgrounds. The lines are on all inputs (vcr, DVD) too. They are tall and appear not to move. There are white lines in between the grey.

Sound like you have to turn down the G2 (screen)controls. They are turned up too high.

I own a PT-56WXF95 and the convergence is out of whack the further you get from the center (ghosting around letters). I understand that there is a 64 point convergence in the Service Menu but I can not...

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Horizontal Green Convergence line on PT-47WX49 is offset to the left 1-2" and can not be ajusted back. The center of the TV viewing picture is the only portion that appears normal.

you will need to replace the convergence ICs and feed resistors. You can get the convergence repair kit for your model at the following link. The kit contains the parts and a CD with the instructions on how to do the repair.

What is STK ICs?

STK-series integrated circuits are amplifier IC's that are most often used in projection TV sets as convergence output amplifiers. When these or other convergence parts fail, the three color images no longer line up correctly on the screen.

Convergence problem not fixed after replacing STKs

I found the chips easy to replace, but time-comsuming due to the number of pins involved. I woudn't want to try it if I'd not had prior experience with soldering.

Still no response to the original question though. With 2 replaced STK392s, red is still not moving in horizontal alignment. What gives?

Hitachi 51SWX20B Convergence problem


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 The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Panasonic PT-53WX53 fast horizontal scroll

Replace Ic7001 and Ic7002 the convergence amps in this unit. Both are STK392-110 Sanyo built Ic's and fairly inexpensive. If you're not at all sure how to replace these take it to a qualified shop. And when you're calling around shopping ask what they charge to replace the convergence amps in these units.
Also take the unit to them rather than pay the pickup and delivery charge, that will save a few bucks.
Have a great day!
