Hi Experts,
my projection tv problem is can't adjust the color convergence. on the screen picture come out are: on top potion there are many lines stake up. on the bottem part is ok. when the screen is on blue background then i can see many curve line at the middle of the screen. curve line is from the left to right of screen. we go to convergence stage try to adjust the color but fail. we adjust the blue color n it can move up/down only, left/right can not mov. for red color, it can move up/down n left/right. we already replaced the conrgence module, problem still unchange. and what else we need to look at. pls help.
best regards.

i had replaced the module part no. is MDCC11.can you let me know the convergence ic no?
to what i understand this MDCC11 is the convergence module accoding to the technician informationed. n i will try to check the resistors first then i will give the comment. thank again for the support.

Terryfic thank for the good responce n helpful. there is no STK part# on my set. there are 12 pcs transistor on the big heatsinks. thier no. are A1049 n C2028., six pcs each. n already comfirmed good.
thanks n best regards.

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 www.TvRepairKits.com
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.
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.

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:
This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.
Make this adjustment only after the TV as been on for at least 30 minutes.
Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)
TO ADJUST IT MANUALLY:
Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu
There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.
Your set is definatly Toshiba 43A9UE has Chassis A9PJ the parts may be hard to find give Toshiba the Chassis number that should be waht they need. Hope this helps. If you need some part in paticular such as a Green CRT let me know I will try to locate one for you, just would need the tube type and number off the tag on the tube.

What is the STK part # on convergence amps on large heatsinks
What is the part # of the DCU replaced ?
Did you replace the convergence amp IC's ?
