I have a mitsubishi WS55819 and every time i turn it on the top and bottom center colapse and the picture is distorted but if i hit the tv it pops back to normal however the problem is starting to get worse what can i do

I suspect what you are describing is a convergence problem---when it acts up go into the customer menu and select convergence--then advanced--it will bring up a grid of lines---if red, or blue is skewed this is your problem.

I have repaired hundreds of these sets--this model uses two of the STK-392-570 convergence chips and I have seen many where the convergence comes and goes--what happens in these sets is not a soldering problem but the pins inside the chips come loose--Each chip has about 16 pins--I have had ones that when I removed the solder pins fell out of the chip.

The pair of chips can be bought on Ebay for about 12 dollars plus shipping (I know the best seller there) and if you or someone you know can do it you can save the set and a lot of money.

Most shops are going to charge at LEAST 300 for this repair--and some will not do it in your home--it can be easily done in the home and takes about 1 hour.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL.

Your tv has three piture tub guns in there. Your convergence board that controlls them to be in align is acting up.
