SOURCE: Convergence problem on a Toshiba 57h81

A service manual won't help you on this and yes it's most likely the convergence amps. That unit takes two stk392-110 Sanyo amps. You can substitue with stk392-150's or 180's also... Personally I'd get them from acme sales in florida along with any solder, de-soldering braid, heat sink compound and other supplies you'll need for the job. Acme, because you are assured of getting originals not some chineese knock-offs.
I'd suggest a package of 1.8 ohm/2w resistors, looks like that's what this unit uses in the yoke return circuit and they commonly have failed, and likely the cause for the amp failure. You might also take a meter to any picos in the circuit. F850, 851, 852 and see if any of them are open. If the amp opened you're okay, but if it went to ground it may have opened a fuse.
I will send the manual via Pando - so if you don't already have Pando go there first and download their free program.

SOURCE: I have a blue shadow that outlines every image.

The problem is in the convergence system which can also cause the tv to not power up or intermittently turn on and off. About 50% of them are bad connections on the convergence power pacs. The convergence power pacs are easily located by the large heat syncs associated with them. The digital control board is located very close to the power pacs. Remove the circuit board housing the heat syncs and using high magnification look for rings around the pins of the convergence power pacs on the foil side of the board. Re-soldering up all the cracked solder joints in the convergence system including the digital control board should solve the problem.

If there are no cracked solder joints in the convergence system, or if repairing the connections does not restore the unit, the power pacs will have to be replaced. Ensure that you apply heat sync compound on the backs of power pacs or they won't last.

After replacing the power pacs, check all of the precision resistors for burn marks or detolerancing and replace as necessary. Next, although rare check the fuse links to the power pacs. This should complete the repair process unless there is some other atypical problem which is beyond the scope of this discussion.

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

I have a Sony KDP-57WS550 TV that has a convergence problem. Based on the symptoms, I'm not sure whether to indict the convergence ICs. In the convergence mode, I can move the red (and blue) crosses,...


With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

Seeing a picture like double vision.Tried to adjust the red & green crosses and the blue. The crosses or plus ( ) signs are supposed to be ontop of each other I assume?. What seems to be the problem.


They have to be on top of each other, converging perfectly. If you are unable to align them - you have convergence issue. Two convergence IC's have to be replaced inside of your TV. I would strongly recommend to let it do by professional technician.

Unfortunately you will have to replace the convergence board in this unit. it has failed. this particular board regulates the alignment procedure that you are having issues with. replacing this board will fix this issue.

Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.

43H70 Blue Convergence out of line and will not line back up


If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
