Convergance Module Can you tell me where the convergence module is . Also I know what a capacitor is and I know what a resistor is. i also know that capacitors hold charges. What I don't know is how to discharge the capacitor so I don't electrocute myself. I used one of the links on this web page and purhcased the training manual but I have yet to find the service manual. Do you know where I can find it? Thanx again

Click HERE for a detailed explanation of how to discharge a capacitor.
Also, the convergence modules will be located on the heat sinks on the main board. Here is a pic of the modules on the heatsink:

But once again , be VERY careful there is enough charge in a tv capacitor to kill you and will probably kill the capacitor (if it has a high enough capacity) due to the extremely high current flowing through it if you do that. The normal procedure is to connect both lead with an appropriate resistance. And not only once, because large capacitors can spontaneously rebuild some residual charge after being discharged (still enough to give you a serious shock). Normally both leads are connected through a fixed capacitor discharge bridge, which stays on the leads while working on the system. Once ready for testing, the bridges are removed.

I would still recommend getting a TV technician to repair this.

My toshiba 57" tv is always fuzzy looking and i do not know how to fix it. any suggestions?


This tv have a problems call CONVERGENCE,it dead.The tv convergence board have the 2 STK convergence ICS and some or all it resistors are dead.These parts on the convergence board must be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Image on screen looks concave(middle of screen looks farther away than left or right side.)


Roseannmace,
Your TV is out of convergance. You'll probably noticed that there are red, green, and blue images. You'll need to determine if the problem is in the power supply or the convergance board. Usually, the convergance amps go bad and opens resistors. Do you know how to read a schematic and use a multimeter? You will also need to know how to remove the old parts and solder the new parts into the circuit board.

Ken.

Hi i have a RCA P52937SG with the bowing of the screen


The problem may still be on the power supply board (one of the supplies may be missing and) when you unplug the supply both supplies go missing check the supply voltages and repost

Toshiba 65H82 Projection TV; location of Convergence resistors


The caps will bleed off within a few minutes of being unplugged. I don't know which caps and resistors he was telling you about but here goes.
Typically along with the convergence IC's the output resistors under the heat sink are at least checked with a multimeter. They are large resistors and should match their color code markings. The caps are probably the caps in the hyper module (hyper board)
Here is a very good tutorial to do this repair or get it done: http://www.dshosu.com/how-to-fix-toshiba-rear-projection-hdtv-wavy-lines/

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergance borard


the convergance is located on the ssb board part #313503712271 but it might be cheaper to replace the convegance amplifiers and the resistors. the amps are STK392-120 the resistors are 6.8 ohm 2watt and 10 ohm 5watt. there are 8 of each starting with location 3149 to 3166. check them with an ohm meter to see which ones are open. there may be visible scorching of the bad resistor.
