My Mitsubishi.WS65857 started with the picture bowing in at the top/bottom, and both sides. Also the color is stretching (hard to explain) with it..After it warms for 5-10 mins it strightens out, but is starting to take longer before the pix is normal.. Any suggestions ? We love this set and its been good for 12-15 years for us.. I'd like to fix it myself..
Thanks, Ted O.
Your TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your conpicture bows in at top,bottom and sides. - 2c07611.pngips are bad and should be replaced. This is a common problem. 
Solution #1
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Solution #2
What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
Usually consumer described bowing is bad solder connects
on pins of convergence IC's. If the effort is made to pull the center PC board out,then replace both Stk392-570 IC's for
durability.
Note: V-Pin amp and pin out relates to left/right side bowed-in
issues,a problem not usually found on your model.
