Im trying to find a replacement screen for a Mitsubitshi VS-70707... is there anywhere I can find one or some sort of similar product that will work?

I know who answered the other question, do you want to attempt the hard reset for this model?

Very simple , you need to initialize you tv by pressing menu and input bottoms at the same time for 30 seconds until the picture coming up and select * intitialize* on the screen menu, and wait until is done and you done.

I know, me too! come on' people, help!:(

This board are no longer in the market.Try website like Tvrepairworld.com might have a rebuild one.It part main board parts of the power unit.

Good day, crsomers1;
The 'giggling' may be a horizontal problem, also known as pie crusting. Try this first: unplug TV from wall, reset or reboot. Secondly: CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 (9-VOLT REGULATOR) ON THE SIGNAL PCB.
I hope this was helpful, good luck, big IRISH.
