The covergence the tv has a auto convergence, which isn't functioning properly. The colours aren't coming together to make one the red is sticking out. As a result the picture quality is very poor.

    I have Auto convergence, but the Colors do not converge correctly on the the corners and bottom. Is there a way to get in there and manually adjust the colored cameras by aligning the different crosses around the screen? My KP-61V80 rear projection only gives me the flash focus option, is there a way to get into the other program, to manually adjust? If so, how can I get in?

This can be as simple as poor connections on the convergence ICs or defective ICs. If you can solder you should be able to repair this yourself. Please let me know if you wish to attempt the repair and I will provide additional details and instructions.

Thanks,
Dan

I thought i might need a lamp for my mitsubishi tv--model VS 60607 when my tv is fuzzy when turned on.should i simply replace the lamp or is there something else i should try? thank you!


This TV is a rear projection television and does not have a lamp. It has three CRT color guns (Red, Blue, and Green). You have a convergence issue (the red, blue and green color guns aren't aligned properly) and it doesn't sound like a very big one. You should be able to adjust this through the CONVERGENCE Menu in ADVANCED SETTINGS.
More details can be found in your manual, here. The model number isn't exactly the same but I'm sure the process is identical or really close. The other option would be a bad IC (integrated circuit) for the convergence control. This is unlikely unless your picture looks something like this: captainhawk1_15.jpg

The problems ur tv having is also parts of the tv Convergence board are dead,but it is totally dead to causes this problems,if convergence board it still have some functions left.Tv will only have colors R,G,B will mis alignments,have colors shadows pictures and 3D pictures look alike,but convergence board are not getting any voltages at all that why u just hearing faint chirping noises that it.The tv convergence board,must require to changes 2 STK convergence ICS and some or all of it resistors too.For the covergence board have fully functions again to solved this problems.The shop will cost u like $300-350 for parts and labors.

Convergence module


That 's actually a very reasonable price for a convergence board replacement in that TV. You can expect elsewhere to be double that or more. Unless you know electronics in TVs I don't advise trying to repair it yourself.

Three colours don't converge


Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider

Three colours don't converge


Sounds like your convergence power supply board is bad if it is a ctc or ptk 195 chassis. Located above the main board on the left and dynamic convergence board on right. Has two plugs and held down with quarter inch screws. Most problems on the board is the IC on the metal heat sink which is stk 730-010. whatever you can see the part number on it. Unsolder with solder wick and solder in new. If this doesn't fix a new complete board will do.
