ok got it off the board just need to solder some tails onto it and have a drink before I try it. never know i could be nil by mouth within the next ten minutes lol.
What is the part codes on q202 and q203 ?? and what condition do they seem to be in cosmetically ? looks like something is pulling the voltage down when you apply the enable 3v, and they are the most likely suspects.
the resistor i have just fitted? if so, without, it reads 14v, with it ranges between 5 and 9 volts when i flick the power on the backlights flash then it dies again and the board just ticks, do you think there is a short somewhere causing it to shut down?
14V is low for 22" monitor. Please see attached picture for some testing you need to see, the soldering works on the caps look pretty bad also. I expect the lamps to flash ON for seconds at least with 14V.
The 8-pin chips on the bottom side are Dual MOSFET's
"244.6 ohms
439.8k
0.1 ohms
5.4 ohms"
Are these the resistance reading that I asked to check by leave one probe on any one of the pins on the right side of the chip (pins on the right are connected together) as shown in my redlined picture, then another probe on each pin top read the resistance? If that's the case, then you have bad chip (shorted).
Can you read the numbers on them?
