My 50707 just went to the shop after it would go into protection mode, worked over a weekend, and then totally died. My technician said that Misubishi may have overfilled the coolant gel in the CRTs when they were first made, and that the gel dripped right on a board where it caused problems. Mitsubishi is looking at my board now to see if it can be fixed. Not all the components on the boards are available anymore. The technician also said that Mitsubishi is recommending that non-flammable drop cloths be added in the cabinet so that any drips will hit the cloth and then be directed to drip off into the bottom of the cabinet where it won't do any damage.

You said you checked the convergence ICs and they're okay - WHAT did you check? Check temperature. Also, try rapping on the heat sink they're mounted on, see if that shuts it down or causes flickers in picture. If those provide no further insight, your problem is bad capacitors on the power supply/waveform generator/deflection board, you will need ESR equipment to check them and good soldering skills to replace. Unit will require in-shop service. A repair bill over $250 is a swindle - we did one for half of that last week.

I have audio but picture blacks out

You may have a bad ground on your vertical IC to begin with! Other repairs would include a bad ground on a coil or the horizontal transformer. The biggest problem is, Yes you have some bad grounds. Repair will be, to find the cracked rings underneath the boards and resolder. Take this note to your local TV Tech, this is your best defense in keeping the the repair cost down! Knowledge, in this case, is on your side now. Good Luck in your search!

MITSUBISHI VS-50801 50" TV

Bad convergence IC possible - It's cheap if you do it your self, expensive if you take it to a repair shop. My Toshiba finally came on and stayed on after the IC's burned completely up and smoke poured out the back. Then mine stayed on with a distorted image.
