I just fixed a similar problem, except my screen was red, not green. Follow your cord directly right of the tube up to the ground wire. My ground wire was a little loose. when i retightened it the screen returned to normal. the sporadicness of your problem sounds the same as mine was. I hope this fixes your problem.

What I usually find on sets like that is that there is a loose solder joint on the CRT board itslef. You must get to the bottom of the picture tubes, pull off the CRT board from the red CRT and examine all solder joints on that board. Chances are one or more will be cracked, and resoldering all joints on the board should clear up your problem.

Add hdmi port to mitsubishi ws-65807

I doubt it as it was never designed for that kind of input, Component works best on this set and it should have only one HD input for a box marked in the menu as DTV.

Mitsubishi ws-65807 series ... convergence going bad? i tried fixing it several times on menu: advance, the convergence red and blue ...it looks well for only about 3mins or so then goes out of sync...

It is very common on these and other sets. Your ws65807 is a V17 chassis that uses two of the Stk-392-570 convergence chips.

These are especially prone to being flaky or intermittant.

I am available here in the Market Place on Fixya to answer this and can provide in that area start to finish step by step instructions for this repair.

Parts cost would be under 30 dollars.

Let me know if you have any questions. SD TECH

MITSUBISHI WS 65807 RED CRT OUT

It' sound like you have a bad crt, to make shure, just disconect the red crt baord and green crt board next to it and move then so you can try the red crt board on the green crt. If it does the same problem in witch I realy thought it's your video or hight voltage sounce on that board. If you get no problem well it's your crt.
I can almost garranty it's your crt.
