It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

HI there,

Check for any bad solder on the mainboard of the TV, and also check for any burn fuse on the powersupply area... BAd solder was very common problem on Mitsubishi TV..

Bad STK ICs they will have PN# on them STK392-570
Mats has them 1-800-628-1118
Replace Both ICs.

1997 model, have you tried the hard reset?

Try - MCMelectronics.com and also Encompassparts.com.

could just be a convergence issue. there should be an auto-convergence feature in the menu. outside of that, you'll have to manually converge the colors seperately (also a feature in the menu).

Seems to be the power button is stuck on the tv itself

I have the same problem have ypu figured it out yet?

you can do a self-diagnosis test by pressing the menu and input/device button on set for 5 sec and see what error code it gives you. Count the blinks followed by a short pause then more blinks. This is the error code.

I had the same problem, it had a couple of bad condensors. I took it to a local shop and total repair bill was $180.00 Well worth it. TV works great now. Glad I had it fixed. ( your cost may be cheaper I live in Po-Dunk USA)
