On my mitsubishi ws65909 I have a 2-2 power light error code, what does this mean? any suggestions, I tried to power it up and the power light comes on and then goes off after 15-20 sec's

the famous code error 2- 2 is for fault in power supply or faulty power supply board. this has to be checked.
and error 2-3 is fault in convergence both the error codes are near to each check out both options. i advise first replace the convergence ic on the board and check.the cost of each convergence stk ic is near to $15 .there are two such ic on the convergence board and both has to be replaced.then check out.if the problem is same go for power supply board replacement.

the ic which you have to remove and replace is stk 393-110 both the ic looks same anve same number .
you can get the required board and components at ----- -------- or from ------ ----
if you are not familiar with doing this you can get it done by local tv repair technician familiar with this model tv.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Hi!! my sony projection tv kp-51ws500 shows double picture. there is reddish outline & its out of focus. i need help to reapir this. please advise. thanks

This sounds like a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400

The Blue and Yellow colors on the left half of the screen(looking at TV) will not adjust correctly. Sony Rear Projection HDTV-Ready TV about 7 years old...

its the problem of convergence on your resolder convergence STK ic's. if that does not work, change (STK-ics).

they ar located on the main power supply board and there are two such ics on the board replace both the ics.and easily available in the local electrical shop.

I'm experiencing different colors on the tv when displaying an image.

If these colors appear to be like a 3-D image, the problem is in the convergence circuit. Please update this with the make and model and I will provide you with further information and instructions.

Green convergence, bad IC?

C8011 could definately cause the problem you are indicating as one side of that capacitor is tied to the postive feed for Red horizontal in IC8001 ( STK392-560) and the other is tied to the Green vertical return . I would replace that along with the IC as the IC is sure to be weakend if that capacitor has shorted. Let me know if you need further assistance.

Sony HS30 Convergance Issue

The STK ICs are located on the D board their locations are IC801 and IC 802 they are both STK392-560 and you will only have to remove the D board. Usually only 1 or 2 resistors go bad right next to the ICs heatsink. You can get replacements at the following link and they include installation instruction plus free tech support heres the link.
