Television and Home Theater

I recently inherited a zenith #ra46m84d OR  I read that #a50m84d is the same and I'm trying to clean and service the cooling liquid for the crts. I just bought the fluid on line and I was looking for a service manual to help me in the realigning of the system. The only ones I've found on pdf is the one that cost $. I've pulled the circuit board and crts out and just waiting on the fluids to come in. Anyone can help me with this?

I have an issue that just popped up 2 days ago. I have a Mits WD-55511 and at the top of the screen I have a black bar that is about an inch and a half wide. Don't know why this suddenly happened or what would cause it. I am hoping it is something simple. Never had any issues with this Tv amd was just telling that to a friend last weekend.

Thank you

Any help very appreciated

Hi all,

I have a relatively old school RCA Color Trax (F35672MB) 36" TV. The problem that I am having is that all too often the cable signal will become really "bad" and get fuzzy. This will affect both the sound and the picture. One swift punch, kick, chop, knee, or thrown object will almost immediately fix this problem (and let me get out my anger lol). The TV will have no problem at all for a day or two, than once it messes up the first time...it seems to happen every 2 minutes.
