Compatibility of Dell 1800FP and LG Flatron 1810B

[MrD]

I've read a number of threads about the Dell 1800FP on this forum... seems that they'll all taken the opportunity to die in the same way at the same time. (Controller board, power board, the stuff near the heatsinks on the power board)

I remember reading that the Dell 1800FP and the LG Flatron 1810B have compatible power board sections, but does anybody know if they have compatible controller boards and connectors?

I've got a Dell 1800FP that won't turn on (I don't have the equipment necessary to test it) and a LG 1810B with an ugly LCD panel (looks like somebody stuck a sticker to it and then tried to prise it off with a screwdriver or something...) I'd like to fix the Dell at the expense of the LG if possible.

Thanks.

It is impossible to know if two monitors contain identical electronics. Manufacturers may use several different LCD panels, logic boards, and power supplies to build the monitors with the same model number. In extreme cases, two monitors with the same model number will have only the plastic case in common. In other cases you will find two monitors with different brand names and model numbers that have identical electronics inside.

I do know that the dell 1800fp was plagued with a power supply problem where the PWM chip went bad due to poor transformer solder joints. Also, a potentially bad inverter (power supply and inverter are separate boards on the 1800FP) if it used an inverter made by a certain company. Maybe all you need to do is replace the power supply? Hard to tell since you don't have any test equiptment. Like PlainBill said, even for the same model, manufacturers used different combos of power supplies, lcd panels, etc. Have you tried opening them up to compare power supplies, etc? If not, open them up and post some photos of the boards per the link below:

You may not need any test equipment. If you open up the Dell and see bad caps, recap with good low ESR ones and that may fix the power problem.

If you don't have a multimeter and you live in the USA, you can pickup good ones for about $15 off ebay. I'm talking name brand ones like Meterman.
