Hi guys,
I am new to this forum and have some questions regards wiring leds,
but first I have just made up a lead to connect my lcd tv to a 12 volt supply in my motor home but got it wrong (+ to - - to +) hence the title of this thread. The tv will now not work, i have had the back off and can't see any fuses or resets, have i wrecked it or what? and is it worth taking it to a repair shop or is it a skip job? any advice please.
thanks dennis
The chances are it's just the power supply that's ruined but it still is hard to repair. You'll need to replace all the semiconductors and polarised capacitors.
I agree, it's NOT designed to be connected to an external 12V source, only it's currect power supply - so it probably doesn't have any reverse polarity protection.
