I bought one of those cheap VGA to RCA converters for my TV (like this: https://www.amazon.com/Lenkeng-1047...LBW&linkCode=xm2&psc=1&tag=duckduckgo-ffsb-20). It worked well for about a year of very frequent usage, then all of a sudden it started showing a bunch of white, red, yellow, green, blue, etc. vertical lines on the TV. I bought another one, it works fine. I'm just curious what could have happened. The capacitors look okay, the whole circuit doesn't have anything visibly wrong with it. Tried different cables and it did the same thing. My only guess is a heating problem, since the case hardly has any ventilation. I would like to know what happened so I can hopefully prevent it from happening to my current one.
"RCA" is a type of connector. The composite video is a signal that can be connected with RCA, BNC, TNC, PL, banana, RJ, UHF, D, barrel, scart, and many other connectors.
The description on the website mentions that thie device can be configured for either PAL or NTSC via switches....perhaps one of those switches is becoming intermittent?
When it's switched to PAL it shows the desktop picture, but in black and white and it flickers up and down really fast. It's never done this. Also, it doesn't have any physical switches for it, despite saying so. Some pictures even show them, but they're not there. The holes in the board for it are empty. It sounds like it's that way with all of them. Don't know what's up with that.
