SOURCE: My Mitsubishi 65 inch DLP will not turn on.
Hi,
looked up owners manual that was a waste of time, hmm the number one issue on this type of set is issues with the lamp. How old is it? Has it ever been replaced? Sometimes a visual inspection of lamp can fool you, but typically as they age a milky haze develops on the lamps glass or if it popped the lamp will be shatttered inside. Can't hurt to check it. make sure set is unplugged first just to be safe.

let it start up you will here things happening, engine will start first then a buzz to start the lamp if you here all of this you have a bad lamp.You should have a error code let the tv try to start leave it alone and see if you have an error. As soon as you reset the tv you loose the error.

Your symptom sounds like at least one damaged convergence IC.
On Mitsubishi's you can sometimes rework the solder connections on each of these IC’s, although, if the convergence does not fix itself from time to time, you most likely do not have a bad solder connection. You will have a faulty IC. Since you now have an error code of 22 (which indicates a short on one of the power supply lines) I recommend replacing them both at the same time because the chips legs can fall off due to the heat of the IC. If you have a good low wattage soldering iron ~ 45W (available at radio shack) you can perform the repair yourself, and this will most likely take care of the entire issue.
I like to remove the board that the IC’s are on so that I can unsolder the connections and clean then up using solder wick (this is also available from radio shack). Removing the board is not a real issue as the connectors are all labeled with an alpha number, so that you can connect them back real easy. There are three in the middle towards the front that I like to mark with a sharpie as they are the red green and blue convergence coil connections (they are all the same size in a row). Just mark them with slashes, like I, II, III, or something like that. If you mix them up it is not a big issue, you can test swapping them around until the picture lines up.
Please be sure to remove the entire white heat sink compound on the heat sink and apply an even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.
There are two very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. I think that the IC numbers will be IC8001, 80002.
The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.
This repair from a good technician will normally run from $250.00 - $300.00, and sometimes more depending on your area.
There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10.00 ones, they are better and more reliable.
I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
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.
You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.
I hope this information allows you to resolve this issue.

SOURCE: Mitsubishi ws-65809 powers on for 2 seconds.
2,2 error code is short protection---98% of the time it means one of the two soldered in pico fuses this set uses is blown----there are several---but your problem means if it is ws-65809 one of the two stk-392-570 convergence chips has failed.
I will attach a photo---they are on the middle circuit board and the two to the right are for convergence--both are green and 5 amp--with the set unplugged check both of them like any fuse--no reading means bad.
If you find this--I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--SHOPS WILL GET 300 or more but you if you can do it yourself buy everything you need for under 40 dollars--I can tell you the best place to get the chips, fuses, etc.
If you want the instructions let me know and I will post them here for you---they are based on my own actual experience doing this repair in this kind of set hundreds of times.

Here is a photo of what the two chips look like--The one in the picture says 392-560 but yours uses two that look just like it--STK-392-570.

Only one of two reasons for your problem--either the DM is bad OR:
These sets sometimes develop a problem with the front keyboard---micro switches in back of the plastic buttons can fail (reset one is common).
Remove front speaker grill and inspection plate behind it and follow the group of wires coming down from the front keyboard to the right top edge of the opening.
About 8 inches to the right you will find two plugs that are inline--they go to the keyboard--disconnect both and turn set on with REMOTE (remote receiver is behind the screen).
If the set now functions you have a bad micro switch on the keyboard (most likely the reset) and two choices---either leave the keyboard unplugged and just use the remote or remove entire screen and get at the circuit board and locate and replace defective micro switch.
Lots of people miss this as a possible choice--easy to do to either know it is the keyboard or not.
If set does not operate this way DM is bad regardless of how caps look.
