Don't think dm board will solve your issue, might want to check power board for buldging caps.

SOURCE: Bad Video Board

In my opinion, if you replace the board you still have a leakage issue. These sets run around $300-$400 in my area. It may make more sense to spend the money on another used TV, or save up and purchase a new TV.

Your symptom sounds like a damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets (I think that this appies to yours)only have one. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

My mitsubishi medallion hd 1080 doesn't show content from component cable

Some of the older Mitsubishi with HD 1080 have only one component input for HD---it is marked on rear as DTV----also a model number may allow me to give another suggestion--Some of these sets (ws, wt, vs models) will on occasion lock out or disable the input/s.

Depending on model number most also have 3 hidden menus---one is the option menu----it allows with the Mitsubishi remote via a 4 digit number (by model number) to enter there and do a hard reset of the set----sets every setting back to factory original---seen it "cure" all kinds of odd problems from missing rear inputs, no sound, odd video issues---you name it.

Get me the model number and I will see if can find the code for yours--you can also try hooking first direct a 1080 blue ray or Dvd if you want to see if the input is active or not first.

Mitsubishi WS55315 rear-projection has gone dark

Yes, they have other than convergence circuit problems----very few issues or troubles.

You should test the shops by asking if they have the 4 digit code number for this model for the OPTION MENU---set has 3 hidden menus and OPTION menu will allow a hard reset of entire set---the other two menus are adjustment and convergence menus.

If some shop has no idea what the option menu is----pass them.

Mitsubishi 65 inch rear projector TV with remote. Model WS65807. HD ready, but not HD. Has failed circuit board, part number 930B866001. This board regulates audio and video. Part no longer available...

Short answer: No.

The board and install will cost you more than an LCD/LED flat screen TV.

Sorry for the bad news, but you will save space and electricity with the new TV.

Next problem: Trashing the projection TV.

RF connector broke from board....looks like part number is 1519592K, but nothing appears when I enter that part do I get new board?


You can't buy the RF connector parts from a TV component supplier as they are already soldered to the main board. A friend who can solder PCBs or a TV repair shop should be able to re-solder the original for you. If it's damaged, a TV repair shop might also be able to find another that will fit as they are fairly standard components. This will be far cheaper than buying a new main board and it's probably going to be difficult to get one.

I had a look for a new main board, but the TV is fairly old and I couldn't find one or a part number. It's easier to find components by part number rather than by TV model, so your best bet is to find the part number on the main board and try searching for that on Google or similar.

If you want to post back with the model number, I don't mind having a search for a replacement main board, but my advice would be to get the existing repaired, if possible.

Hope this helps.

How do i change from 480i to 1080i on my mitsubishi ws55315

You can't. Depending on what the output device is sending and what input you are using ion the back, it chooses for you.

ie - if you have a DVD player sending out 480 the TV will only allow different versions of 480.
