Question about Mitsubishi WS-65809 65" Rear Projection Television

1 Answer

Have a mitsubishi ws 65809. Recently started flashing from color to black and white (the color is off with not a lot or any green). The volume also was at one setting even after adjusting it. We did take it apart to look and the screen went green after turning a nob.

Hi


Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. Also check the 5 amp fuses F9A04 and F9A05, they are near the power transformer, and are about the size of a grain of rice. They are soldered in; replace both of them (even if one checks well and the other is bad). There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

This is unusual for this model, can you tell me what source you use for signal? Cable? Sat? Direct TV? Also how are you connected----via the coax fitting or the rear AV jacks.

Image problem with WS-65809 65" Mitsubishi Projection TV


WS-65809?, if convergence is skewed and comes and goes, uses two of the STK-392-570 CONVERGENCE IC chips.

I have seen a lot of the Mitsubishi sets that use these two chips where the convergence jumps in and out. You need to replace both chips and adjust the set.

You can buy a pair of the chips on EBAY for less than 13 dollars plus shipping.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THE SETS THAT USE THESE TWO CHIPS.

If you or someone you know can do the repair you can save the set and a lot of money--most shops are going to get at least 300 for this kind of repair--I know as I have done hundreds of them here.

The instructions tell you everything you will need and how to do the repair. I have helped many people here do this based on my instructions.

If you want the instructions let me know and I will either post them here or send them to you.

If this information has helped you, rate this solution as I do this here for FREE.

65" Mitsubishi projection tv, my colors are not matching up.


If red or blue will not adjust in some direction--you have a Convergence circuit problem---

This model (WS-65809) uses two of the STK-392-570 Convergence IC's---

Green for a good reason is not adjustable in the customer mode---it is only adjusted for the Geometry or straightness of the picture and then red and blue are adjusted to it.

If you are able to do this repair yourself you can save the set and a lot of money---most shops charge 300-400 for this type of repair in this set.

You can buy both chips for about 14 dollars on Ebay- and I have step by step---start to finish instructions for this repair in this set--they tell also everything you will need to do and what you need.

If you want the instructions let me know---I am not allowed to post MY email here.....but you.....

Not everyone can do this repair---Let me know if you have any questions or need advice----

If you get someone else to do the repair make sure BOTH chips get replaced or the set will have the same problem again in a few months.

We would need to know the model number. you have indicated that it is ws-65809 but i don think this is your model because what you are describing is a bad dm module and the ws-65809 doesn't have one in it. Let me know and I can help your further!

MITSUBISHI 65" WIDESCREEN MODEL WS 65809 (GREEN GONE, SMALL RED LINES)


in the front cover turn up screens on all colors till you see retrace lines, then back them down to where dissappear. enless you know the correct voltage to set it. as for the green. i would try the red crt on the green and see if it looks ok. if so then replace crt circuit or check transistors on crt circuit may also need to change the driver on the heat sync.
