Question about Toshiba TP55H60 55" Rear Projection Television

3 Answers

Red is way out of convergence/alignment

I just picked up a 55H60 for free from a relative for my basement. Unfortunately the red is way off in comparison to the blue and green CRTs (mainly on the left side). I went through the convergence process in the user menu but can't get the red to adjust far enough. I was considering going into the service menu to see if I could pull it in from there. I don't have service menu experience with a Toshiba but have made many adjustments on my Sony RPTV. Is it possible to fix the red alignment via the service menu?

    Thanks Hardrocko. Before I got your reply I wnet into the service menu and adjusted the red in pretty well. After about 5 minutes the red then popped way out from where I had adjusted it. The horizontal linearity bowed out big time. That leads me to believe that it's component related. Does it still sound like the convergence IC is bad?

    Hey Hardrocko,
    I finally found thhe 2 ICs you were talking about. I must have laid there on the ground about 6 different times looking for the ICs. I was looking for IC chips not those honkin' things. Doh!! From behind the set I had to use the reflection of the shield on the back of the digital convergence board to see the ICs. STK396-110 They run about $17 a piece at Do I have to pull the entire PCB out to get them out or can I cheat and access the soldering from beneath the set by removing the vent screen? I'm comfortable with soldering and safety but without a service manual I may not remember all the connections on the board once removed. Also, the plastic parts within the chassis are extremely brittle and I'm sure a standff or two may break.

    If I decide to go with a pro, what's your guess-timate on the labor for the repair?

    I made a mistake on my previous post. The part number is actually STK392-110T. Can't edit a post, bugger!!

    I have a Panasonic HDTV and there's a blue shadow. I tried to align with convergence but blue goes so much and doesn't converge to the "plus" signs. I opened up the TV and unscrewed the (green) concave lens and some fluid came out, closed up immediately but when I turned the TV, I see green blur. Is there any way to ad more (green) fluid back in AND converge the blue?

    Micmay, I have the exact problem with the red on my TV. Did you replace the convergence ICs and did it fix the problem?

  • Anonymous May 05, 2008

    PT47wx42 Panasonic just had both convergence IC chips replaces as well at the resistors replaces, can not get red to converge. Top of tv picture is bowed!

    i have the same problem the red shows offset to everything is there a special part i need?

If the convergence adjustment is not moving the beam chances are the convergence IC(s) are defective. If you know how to solder and understand TV safety you may be able to fix it. With power disconnected remove the back. You should see two large heat sinks with large ICs (3 by 6 inches) with about 30 leads going through the circuit board. Numbers on the ICs should usually be something like STKxxx-xxx or some variation with x being a number. These ICs control the position of the three beams. If they go bad you can't adjust one or more beams. Replace them both as you don't want to get in there again in 3 months. Cost is not that much. or should have them at a reasonable price. Before replaceing the ICs look at the circuit board closly for cracked solder joints. Resoldering any bad joints might just solve your problems and avoid replacing the ICs. Good luck and remember safety.

    Certainly if you have adjusted it and it moved again it has to be a component problem. Sounds like the problem I talked about. If you are not capable of this repair you will need to have a tech look at it. Good Luck.

I would concur with the other solutions. My green convergence went way out and could not be adjusted in the service menu. I replaced the STK392-110 ICs ($5.99 apiece from and it fixed the problem. I have a follow up question though: some other forums have said that I should have replaced all of the resistors connected to the ICs or my solution will be short lived. Others have said that I might have to replace the resistors if they had been burned by the failed chip. Should I open it back up and replace the resistors as well? You can read about my fix here:

Maybe it's just me.. am I doing something wrong? How come discussions like this are around topics not related to the heading???? This is clearly a 'troubleshooting' topic under SONY GRAND WEGA KDF-60WF655!

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

If the tin can module you are referring to is the hyper module, it is common to replace all 11 caps because the factory caps ****. Check for bridged solder connections at STK's search the forum at electromaniacs for 50h81 :)

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

My screen looks like its 3D.

Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

It looks like the bulbs are not aligned. The upper half of the picture is fine. The lower half has the red above the blue to there is double picture. I just picked up the TV for free. Any suggestions?

This tv have a problems known as a convergence problems,it dead.The tv colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have 2 dead STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.

What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Hello, I've got red wavy lines across screen

There are two common problems with these sets.

Problem #1) Convergence

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

You can see some examples and find a fix here...


Picture is very red and slightly distorted

A very red picture is usually related to the Red CRT or red CRT drive board being defective. The convergence will only mess the alignment up and cause the picture to appear 3D it wont make the Picture take on alot of red tint.

When tring to use the red convergence it seems to be twisting.

Go to this Blog. It "should " solve the problem.
Really, Really simple, do it your self solution !!
Instructions and pictures included :D

Ken , the poster of that Blog writes........

"The problem is with the convergence via the voltage on the
color ray gun tubes that get out of adjustment.
They are also known as retrace lines."............

This blog covers many makes and models with many
issues solved, just with that one solution

Give it a try, it's FREE and SIMPLE :D

Hope the blog helps you also :)


Pioneer SD-641HD5 red convergence - not chip problem!

Replace Both of your STKs if they are STK392-110s do not go back with them use STK392-180s better ICs, The 110s fall apart and do not hold up.

Red convergence

You ned to replace both convergence ICs they are Both STK392-570 You can get replacement ICs at the following link with free instalation instructions with pictures. Heres the link.

Panasonic PT-53WX42

convergence IC bad

Red convergence wont move

if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........

convergence STK have nothing to do with the red being blurry
