Tested continuity on all the solder points and all wiring back-in place only powers up for 3 sec. then off
How did you get at the part/s? remove chassis or just the center board? I suspect something happened when you repaired the set.
Does the self check which even if set does not come on, power light comes on for a few seconds and goes off, do the self check (let me know if you need to know how) and see what blink code the power light gives.
SOURCE: powers on for three seconds then goes off
The first thing to do is to try to determine why the set is not turning on. It is equipped with a self diagnostic feature. On the front of the set push the MENU and DEVICE button at the same time and hold until the LED starts flashing a two sequence code. That will narrow things down for us.
SOURCE: how to reset convergence? on mitsubishi ws 55511,
There is an option in the user menu on the tv. Using either the remote or control panel on the front of the tv, press MENU then select SETUP. After you choose SETUP go to the 3rd column with the 3 icons. Here you can adjust the red or blue color or reset the convergence back to factory default.
After a few years the set will begin to show increasing problems with the convergence settings. When you can no longer adjust either red or blue horizontally or vertically an IC replacement will be needed. Your set uses (1) SANYO stk393-110 and you want to make sure it's SANYO and not a knock off brand as those usually fail prematurely.
SOURCE: Mitsubishi WS-55511 convergence problem?
No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.

Easy fix, pull the DM board ( box with the digital audio orange plug to the left of the patch bay)
this box has several multi cable plugs , but all are labeled with a two letter system and so is the board where they go this makes it easy to put back together
Pull out and open the box ( about 12 screws and then pull the cover off) you will see a small board with 3 cables attached, pull this board by removing the 4 screws and then replace the 7 capasitors with a 25v 1000mf or 35v 1000mf either will work, the 25 volt fit a bit easier. make sure to put the longer leg in the + position on the board! ~ now replace everything and enjoy your set!

Rear Projection HD set, Mitsubishi WS-55511
Nature of problem: Blinking green light of death. Upon plugging the set back in after vacation, the green LED on the front of the set would blink continuously and the set would not turn on. I ordered the blinking green light kit from tvrepairkits.com after seeing this link on a tech forum, suggesting the capacitors were bad on the DM board inside the DM module. The kit arrived within days of ordering. The online instuctions were very detailed and could be followed even by a layman such as myself. Very detailed with lots of photos. My DM module was simpler to remove than the instructions indicated. It simply slid out after about five cables were disconnected from other boards. The module itself is the silver box all the way to the left when looking into the rear of the TV (from the rear of course). There is a plastic guard that surround all the input connections (coaxial connections, home theater control inputs, etc). This is removed with 3 screws. After all the cables to this module are unplugged from other circuit boards, the module will slide out towards you. Then you take the cover off (including the clamp where all the cables are routed into the module) and you can see the DM board (it is labled as such and has 7 capacitors. None of the capacitors were bulged or otherwise defective looking as other posters have reported. Changed them all anyway. Buckled everything up and plugged the set back in. The blinking light started as it always had. It should normally go out in about a minute after plugging in to wall. I really didn't hold out a lot of hope that it would go out....and then....it went out! I pushed the power button and she fired right up! What a thrill! Including shipping, it cost me $45.90 to fix a set I paid about 3000 bucks for 7 years ago and was loathe to just throw away. I certainly wasn't going to pay nearly a thousand bucks to fix this set. It may be a little bulky, but the picture is beautiful as well as the sound system. You guys are great. A very reasonably priced gamble that worked. Watching a movie in HD while I type this, good to have my TV back after almost two weeks without it. I actually can't believe I did it!
