Anyone familiar with this?

I have a problem that has struck both of my Master Systems (both the first model) at the same time: Even though there's an open feed to the T.V., neither console sends a signal through. No matter what T.V. I try them on, whether with A/V connection or R/F, there's no improvement.

Though I can just get another one, if it's just a simple problem I would prefer to fix it.

Anyone got an idea of what the cause could be?

If only video is missing, the video encoder could be fried. If audio is gone as well, it could be a bunch of things (power supply, CPU, VDP, glue logic...).
