Just got a RFM and it's acting strange. Anytime a coil pulses I get red lines on the monitor. Plus colors go in and out.

Just curious how to fix this.

Just to be clear, we are talking about the main board under the PF? I secured the monitor board in the head.

Okay,

I cleaned everything and it got worse. I am assuming I need to take the 4 screws off the back and remove the board.

I did see this ground wire floating around. Should that be connected to something?

Any help is appreciated.

Well can someone tell me what I should touch to discharge? Plus do I just remove the four screws on the backyard to pull it off. Someone has wedged paper in between a gap. Really wish I had more experience on RFM . I started to take it apart and all of this stuff fell down. Curious why a switch was jammed in there.

Quoted from LTG:

Nothing.
Google how to discharge a picture tube. Follow carefully. Don't kill yourself.
LTG : )

Thanks. Does anyone know why that paper would have been shoved in there?

Quoted from tonyhoff1:

I had the same problem, but was getting only blurry red and not even enough red like it should be, Rebuilt the chassis still the same way. Did everything I could with the chassis. So decided to install a LCD, Did not think I would like it. But I have to say I do. It puts everything where it should be. Sad part is I have less in all the parts to do the LCD then I put into the monitor itself!

How do you do a LCD? Do you use a converter kit or just run a new Vega cable to the LCD? I am assuming a lot comes out which is never used again.

Where did you get the converter card? I may go this route. Im guessing a 4:3 monitor and not a 16:9 is needed. I wish someone still had the mounting kits.

This is awsome. Anyone have suggestions on monitors?

Quoted from tonyhoff1:

I have a 20inch in mine. 4.3 if interested I can sell you my other lcd

I ordered the kit to have as they may get harder to find in the future. I may be interested in the 20 inch monitor. I need to check around as we may have one at work or somewhere else. I guess you need a 20 inch monitor only.

I fixed the board and ran a continuity check.

Can someone tell me if the last 2-3 pins far too on the connector in this picture go to ground as I get continuity to the chassis bar and I cannot find out if they should or should not have continuity.

Afraid to turn on till i can confirm.

Here's a better pic. Cannot find the schematic to tell me if these lines should far left of this connector should be tied to ground.
