Red convergence real distorted for mitsubishi ws-65807
I've read numerous articles online regarding this television set (mitsubishi ws-65807) for convergence problems, my tv red convergence is way out, will not align horizontaly and gets worse from the center to the sides of the television, mostly on the lower right, the red convergence on top of the picture is wavy, i've read about replacing the ic's or what have you but I need photos or parts descriptions so I know what im looking at. im very good with electronics especialy automotive. is it worth the repair that the tv is 5 yrs old and somthing else might happen soon or should i just get a new one with a waranty this time, I live in the bay area and they want $300 to $400 just to come to my house, who knows what the total would be. that would be a good down payment on a new one. any smple fixes or suggestions would be appreciated, sory about the spelling i make money with my hands. I have had the tv apart to search for anything obvious, all solder conections look good and everything else seems good other than the fact the inside was very dusty but thats been taken care of. thank you for youre time.

Re: red convergence real distorted for mitsubishi...
A man with your experience won't need photos.
1)locate center PCB--has large heat sink--
2)using a hook tool,gently lift board edge connectors.Go slow,be gentle.
3)remove all connectors to center board (unplug)
Don't worry about getting them mixed up--we
have a saying--they are idiot proof.
4)remove all center board hold-down screws,includes two in sister board shield and
three difficult to access in large heat sink shield.
5)gently lift PCB up and to the right while
releasing hold-down plastic tabs on the front e of PCB.Replace STK IC's.Throw it in reverse-done

Hello. There is no separate power supply in your TV. It is integrated into Deflection Board. I would recommend you have real professional diagnose your TV, power supply section is rarely goes bad, it could be convergence or some other issue. Regards. Russ.
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. You can get a repair kit with parts and instructions from www.TvRepairKits.com
yes the convergence Ics are what cause the two picos to be open they are both 5 amp picos. You can get the picos, the convergence ICs and the factory service manual for your model at the following link.your model is known as the V17 chassis for service manuals and you should require two STK392-570 Convergence ICs. Heres the link they provide free instalation instructions. http://servicemanuals.vstore.ca/
I replaced the pico fuses and the convergence IC's. fuses poped right away code 22 . Further inspection of the board showed the coolant had leaked out of the center projector and fried the board. Not willing to pay $300. Passed it on to someone else
go to this websight leave an e-mail with your model number and let them know you need a signal board and they should be able to help you plus there prices are very reasonable and they also offer free online tech support to their customers http://servicemanuals.vstore.ca/
This may sound crazy, but applying heat with a hair dryer to the center lower air holes in the back of the tv just above the power cord for anywhere from 3 to 10 minutes solves the problem. But it must be done everytime the TV is turned on
