Question about Mitsubishi VS-50705 50" Rear Projection Television
Need some help with this one. Had this set for around 8 years and no problems until now. Lost video while watching tv, sound and channels change fine. Would like to see if I can repair the problem. I checked the set inside for leaking crts and checked the four fuses and they are good. Need a little help where to go from here. I just ordered a service manual on CD, not sure if this will help but will at least be a good reference I hope. Thanks for any help with this set. Dennis
Good Day, FamilyGuycruzer;
OKAY! Some way / how your TV started working all of sudden for at least 3-4 weeks then developed a different concern.
Well, let's think about this?????????????????? Still thinking
....................................., OH, maybe the HIGH VOLTAGE Cables are loose they are the right side of chassis (looking back) towards the rear of chassis. Check to make sure that they secure and any other connection are secure and seated properly.

Good Day, Dennis,
I'm glad it's working for the time being, which leads me to ask you to check this out, since the problem seems to come and go. Please remove front speaker cover, it just pops off, then remove the small black panel in the center TV front.
You want to look for fluid on PCB's, this 1999 model was known for this. The spots are very small, sometimes the size of a dime. They could be clear, or greenish with blackish type mold (corrision). Use bright light it's hard to see.
This fluid comes the TV's picture tubes, they use ethylene
glycol to cool the tubes. It's easy to clean with power off, unplug for safety reasons, use acid-tone, Finger nail remover, with paper towels & brush (tooth) to remove fluid.
Put heavy plastic or thick card board over affected areas.
Good Luck, big IRISH.
