I have a Mitsubishi WS-55819 and the screen is curved and looks 3d. The colors are also blurry. When it warms up it looks better. Any suggestions?

It could just be the solder on the convergence ICs which needs to be reflowed. If that doesnt help then the ICs will need replacement. Your model uses 2 of the STK392-570 ICs. If you need further assistance please let me know.
Thanks

Ws-55819 has code 22. It will power off within seconds.

Error code 22 on this model is most freguently a problem with convergence. Error code 21 is usualy the DM module.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Convergece problem - Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some images of convergence problems.

Picture is double and colors are out of focus looks like 3d without the glasses

This is a common problem that would require 2 Convergence output IC's to fix . The part # STK392-560 replace with STK 392-570. a repair shop would charge between $200-$300 (parts cost $60.00)

Mitsubishi WS-55819 power issue

No, that'll do it. Once you've changed em you'll know right away if somethin isn't right. But take faith and fire that puppy up. If the pix is good you did good. If something is amiss. I'd be happy to walk you through it. My money is on you though.

Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.
