HELP!! I have TRON upright that was working great until I plugged it in this evening. It appears that everything is working but the monitor. The sound is good and all other op, but all I have on the screen is green horizontal lines. Is it a chip on the I/O board or something else? Any suggestions? Thanks.
 
Try a cap kit, if that does not fix it the you will have to look for other problems in your monitor.

Cap kit? I was electronics tech many moons ago in the Navy, but am now getting back into the game. Thanks for the reply.
 
do you have any other games with working monitors, that you could swap in or link up?

I would make sure (while the game is unplugged or turned off) that all the connectors appear to be good.

I don't have any other games. My TRON is a very well re-furbished game. I've spent a long time looking for the right TRON upright. Like I said in my earlier post - it was working perfectly fine until this evening. Plugged it in and no video - only green horizontal lines on the monitor. If I was blind - I could still play the game, because it appears to working fine except for the vid. Evidently, the sound board is working. Is there an IC on the CPU or I/O board that might be the culprit, or is the monitor the "bad guy"? Thanks.

Just a thought - the interconnect wiring harnesses on the boards appear to be a bit "brittle". Could that cause the problem?

As a matter of fact - I sent him an email today in regards to the ribbon cables. I figured it would be a good idea to have replacements on hand in case I had problems in the future. I didn't expect it to happen the same day I sent the email. What is the link to order the replacement ribbons? I don't know if that's it or not, but I would rather deal with that than the monitor. If you have any other suggestions regarding my problem, I would appreciate it. I can fix it, if I have the right info. Thanks.

Thanks. I have the original ribbons, so it definitely wouldn't hurt to replace them. I don't have the feeling that's the problem, though.

Before this happend did you move the game or anything that may have caused something to come loose? The most common monitor in Trons are the Wells 4900. With no video signal they have a green hue on the screen with lines sometimes. Can you post a picture of the screen when the game is on and the back of the monitor so we can see what kind of monitor it is and if everything is hooked up? That would be a big help. Be careful of going on an Easter egg hunt just randomly changing parts with out actualy diagnosing anything. Might cause you more problems.

Thanks for the information. The screen does have a green hue with lines, so you're probably correct that there is no video signal. The game was moved when I purchased it, so something might have come loose in transit and finally decided completely disconnect. I will post a pic as soon as the battery charges in my camera. Again, thanks.

Pic of monitor screen. Doesn't appear to be anything loose in back, but will send a pic asap - camera battery went kaput!

That is a 4900. And it looks like it does not have a video signal. Check the brown cable going from the PCB stack to the left side of the monitor for a good connection.
