LG E2360 - LED Monitor

[JoeyJoe]

Hi,

I bought this monitor on the cheap. It's just over a year old and has had a fault where the screen started to go blank after an hour or so. Now it doesn't turn on at all.

It has an external 12V power supply that is running at around 13-14v. It seems to be dropping in voltage slowly, not entirely sure why.

Does this look to be a power supply problem? and has this damaged the logic board?

Thanks

Joe

I am no expert but Power supply may have bad caps try another power supply. Sounds like it' over heating lower led bulb intensity. open up case and check caps on mainboard.
I hope you have an ESR meter.

I use a normal multi-meter and do the ohms test on them. The caps are tiny, not seen those types fail before.

But since there is no power at all, nothing! no LED lights, just some high pitched buzzing. I'm guessing it is dead?

Why would the 12V supply give 14V? is this normal?

Might be a good time to post some good focused photos of the entire main board.

That power supply should be regulated 12V switching power supply, it should not be putting out 13~14V.
