Good Day, bigjim;

No inner tube. The tube may light up but it no video bias to turn the tube on, or the tube is so gassy that it doesn't emit properly.

It sounds like you will be in the market for another TV, because it sounds like like the CRT may be bad.

Hope this was helpful and not tooo late.

Good Luck, big IRISH.

Mitsubishi VS-50603 Wont Turn on

The power supply will need to be changed. The capacitors inside the power supply are not sending the correct amount of power to tv and will need to be changed.

I would highly suspect that the TV's signal board has CRT Coolant (fluid) on it. Check closely and remove/clean with acetone. Good Luck, big IRISH.

I have a Mitsubishi VS-50603 that will not turn on.

Good Day, jessayala;
It sounds like you may have Ethylene Glycol on the boards, leakage from the TV's CRT's. The Glycol is a fluid that help's the tube cool. If you are not handy, very, very handy, I would call an Authorized Service Center to come out and give you an estimate before the repair is performed.

Good Luck, big IRISH......PS..... If can handle your self ..... come back here.

1998 mitsubishi big screen model VS-50603

this model is famous for fluid leaks. each projector tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
Once you
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.

We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.

You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.

Clean the boards carefully and repair any corrosion damage. The coolant is
ethylene glycol and glycerine which is water soluable.
