I was lucky enough to obtain a JVC VM-R200PSN for the low-low price of nothing. The only potential problem was it's unknown condition, as it had been stored in probably not the best conditions for the last few years. Opening it up revealed quite a surprising scene - there seems to be a colony of mildew (mold?) residing on various components inside. However, there is no other visible damage (apart from a small spot of rust on one heatsink), and all the electrolyte caps seem to be in a good condition. My question number one is, whether after a couple of days of drying (as there could possibly be leftover moisture), could I hope to expect a picture? Or if there was a sufficient amount of moisture for mildew to grow to begin with, the monitor is most likely already dead?
While I was at it, I also picked up 2m of RG59 cable, and 5 BNC connectors, which, as I was told, were 75 ohm ones, intended for the cable. However, later in the evening, some googling lead me to believe that they are actually 50 ohm ones, as suggested by the diaelectric present inside the connector. This poses the question number two, if the monitor expects 75 ohm input, could I use these connectors without risking killing it or the equipment or getting NOTICEABLE picture degradation?
The connectors were picked up with the intent of making a couple of cables (which I of course could've ordered form eBay, but I didn't. Eh. I tend to make many a bad decision about cables). From there, my third question arises - how would I go about connecting a 1) VGA source (one that can be made to output at 15 kHz and a 2) composite source outputting on RCA. I'm not worried about schematics, but rather things like: if on a normal BNC cable the impedance of connectors has to match each other, how is this insured in case of, say DB15 to BNC or RCA to BNC cables?
Sorry if this post is unintelligible, or has been answered before - I do not exactly posess good information processing capabilities at 5 in the morning.
