Re: Gateway LP2407 Power Board.
The fuse is bad. measurung over 200 ohms, about 391 - 600 ohms. I tried 200ohms but out of range.
The bridge rectifier pins 2-3 has no reading at all. just the other pins that works.
would this mean I have to replace every component that is shorted and burnt out.
The 2 burnt resistors, I don't know the color of them as they just look burnt.

Re: Gateway LP2407 Power Board.
The power mosfet is getting about 8.30 ohms on each pin resistance.
The Fuse,I cannot test the fuse in ohms. not showing value.
The brodge rectfier is showing with diode test
pins 1-4 =1595
pins 2-4 = 717
pins 3-4 = 713
pins 2-3 = no value
looks like somehow, just not powering the whole board.
Those blue resistor are working too.

Re: Gateway LP2407 Power Board.
The resistors (yellow) does not show any value. The outside resistors on the board are working. I don't know how to test blue ones with color code.
I don't know what the resistor value for the pink resistor circled in yellow. looks toasted really. can't tell what color band it is.
The bridge rectifier is showing 0.10 - 0.12 on 20v DC test.
The power mosfet also doesn't show value.
Yes, I need to replace that C854 Cap.
The fuse is showing 0.89 - 0.90 amps

Re: Gateway LP2407 Power Board.
I bent the cap straight to show you the burn mark damage on the board. The cap is the right value. I'm guessing its the transformer that looks burnt. I couldn't clean the burn marks off. I tried using Isopropyl alcohol to clean it. Only managed to clean off a bit. Still showing shiny burn mark on board.
I used my samsung phone to take pics....

Re: Gateway LP2407 Power Board.
Yes, I do have some experience using a multimeter. I don't know the history of the monitor. I bought the monitor off someone who says it may work or be sold as parts. I guess they used it for some time and the power board started to burn out and stop working. I'll upload the pic a bit later.
Is the board still repairable?? By the looks of it, the power transformer and some resistors are burnt out.
If not what other alternative or similar power board that will work for a Gateway LP2407 monitor. I am in UK. Trying to find...

Re: Gateway LP2407 Power Board.
I have got 1 or so bulged caps. I'll replace them but there is burn marks on the power board itself. Burn Marks are circled in red. Although there is no power to the monitor. Please help....

Gateway LP2407 Power Board.
Hi, I have got a gateway LP2407 monitor and the power supply board is burnt and dead.
Are there any alternative power boards that will work in a gateway 24 inch monitor LP2407.

Re: New Members - please post your introductions here
Hello everyone. I started tinkering and repairing faulty electronics, hdds and monitors. I just got a Gateway 24 inch monitor that has a bad power supply, looking to replacing the swollen caps and the pink resistor that burnt out. I like fixing things, it's my hobby.
This site is cool, Its got everything I need to find out.
Thanks
