Megatouch Radion Force - Tatung C5GNEKC Monitor help
Hello all!
I need your help/advice....
I know nothing about fixing monitors but know my way around other electronic items and I am very comfortable with a soldering iron...
I have a Megatouch Radion Force that the Tatung C5GNEKC CRT monitor has stopped working. I have confirmed the issue is the monitor and not the Megatouch itself.
Symptoms: There is no picture on the monitor. The monitor is powering on and powering off. There is a green light on the remote control board that turns on and goes out as long as there is power. It cycles on/off/on/off/etc. There is a relay click sound when this happens on the main board. You can also here the normal "buzz" sound when the power comes on. Nothing displays on the screen at any time. Prior to this issue the monitor looked great and had no issues.
I looked at the main board and I can see there is a yellow square capacitor right next to the flyback transformer that the magic smoke escaped from and looks like it is melted and burned. I found a schematic on-line and I think it might be C480.
Might just replacing this capacitor fix the issue?
I know that some monitor issues can be fixed with a cap kit. I would be willing to give that a try. But if the costs/work get much higher than that, I would probably just pull the monitor out altogether and replace it with a LCD monitor.
I also happen to have a fully working identical Megatouch that I can use to test parts if need be...
How do I go about narrowing down the bad parts? I know I have a capacitor that is melted, do I just identify it, buy a new one and solder it in?
Pictures...
The first picture is what my Megatouch looks like.
The second picture is what the burnt capacitor looks like in my good machine.
The third and fourth picuture are the burnt capacitor.
The fourth picture is a schemtic I found.
Thanks!
Dan
