I've looked for a schemative for the main board (715G1423) and have found nothing. Any assisatance you can offer me in respect troubleshooting the main board would be greatly apreciated. Thank you!

Three things to look for in service with LCD monitors,
1 bad capacitors
2 Bad transistors for the back light feeds
3 bad ic pulse chips for the Non function circuit
you will not find schematics unless you peruse the patent office records, reverse engineer the circuits and you will have a schematic
when the main chip fails on the vga board its time to buy a new vga video board,
sounds like your board may be suffering a bad IC telling the main chip the power is OK

let me know how it goes.

Battery on my 2010 sonata reads 12v. but car will not start


First put a full charge in the battery...It takes about 13.5 volts to properly start you car due to starter load..Your 12 volt battery will show 12 volt no matter the state of charge..you must have it load tested...meaning how many volts the battery is putting out under load " starter engaged " a weak cell will cause failure of this test.. any of tne auto parts stores will test it for you...good luck

Samsung plasma TV cooling fan didn't turn on and the TV overheated. Tried replacing with a new fan, but that fan will not turn on either. TV works just fine with back cover removed and a 12" desk fan...


the is a fuse on the board if you follow the power line on the board back to the main power board you will find it. also test the volts with a meter just make sure you have volts. some of these models also have a thermal switch that then the tv hit a surtan temp the fan kicks in.

Honda EU3000is. 2 year old unit used by electric start at least 5 days a week. My gen has recently stopped staring by the electric start, it turns over but just not as strong as when new, what i mean by...


I have a 5 year old EU300is that would not start with or without the battery. I went through all the usual such as gas, plug, oil, etc. The battery showed 12 volts, however, when tested further it would not hold a load. I bought a new American made battery and now the unit runs fine.

Pontiac G5 only starts when jumped. Battery tested out fine, Alternator tested out fine. Not running any codes...Now what?


Was the battery "load tested"? lotso f auto parts stores just test for 12 Volts across the terminals. You ned to have it load tested. Thats where a load simulating the starter is put on the battery. I have a carbon pile tester that places 500 Amps on the battery. many times I have seen a battery show 12 Volts and fail the load test due to a dead cell.

If it's a side terminal battery, it's really hard to get a good clean connection.
