I am starting to get static on the screen. The picture is generally pretty good but the screen will be will start to scramble and looks like there is some type of static causing it. If I hit the top of the TV, it clears up. It?s very random; sometimes we have to hit it several times in an hour. The picture is still good but I have noticed there is a slight darkening in two of the corners.
Do you know what is causing this is is it worthwhile to fix?

Re: Static on picture
The more you hit the set and wait to get this problem fixed ,the more its gonna cost ya. Your problem is a very common one for RCA. Whats happening is theres several grounds around the tuner sheilds and tuner covers that are intrmittanly going bad because of the differant types of materials they used for the sheilds and covers , so the metals are all reacting differantly to the solder ing in the set. This set if not fixed right away will cause the eeprom to go bad and or the vertical swwep Ic to fail. The repair shouldnt cost more then 125 to 175 bucks or your getting ripped off!! Happens all the time . Good Luck

Sounds like a high voltage power supply problem. With the TV on, check to see if CRT has a static charge on face of screen by placing back side of hand in front of it and feel for static charge. Also you could hold a piece of tissue paper in front of the screen to see if static electricity from the CRT attracts it. If no static charge is present, the problem is more than likely in the high voltage power supply. Unless it is something simple, like a loose connection, it would probably be cheaper to replace the TV. Do not probe around in the HV power supply while the TV is on--it could prove deadly.
The horizontal line indicates failure of vertical section, checkout the output capacitor of vertical-section connecting to the yoke (vertical) for any loose contact, dry solder, capacitor wear-out.
Need to check the register and filter capacitor that powers the vertical-section.
You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.
Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.
Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...
It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck
The problem you're describing sounds like a tuner problem. BUT you say that you have the
same problem with A-V input too. That's weird!!!
Possibly the electronic TV-AV switching circuit is messed up and stuck in the TV (tuner) position. If this is the case you DO have a tuner problem and a switching problem too.
