Re: Asus vg248qe purple light problem

This is the eeprom EDID, most likely the spi and eeprom are on the back side.

On the back side there is one 24C16RP

Added pics of the other side aswell.

I suppose the EPROM ones are the 2x 24C02RP chips on the last pic?

Added some pics, the C420 and C433 (red circle around) were the ones that were short circuit / missing.

Of course, first you need to check the compliance of the voltages 5/3, 3/1, 8. Well, show a photo of the damage site

You need to have a programmer, firmware, unsolder the chips ( possibly replace them with new ones ) , and update the firmware using the programmer

Alright. Is it possible that it happened because there was a short circuit ? Previous owner of the monitor tried to fix something on the main board. (the part where the power board connector is). One SMD capacitors was short circuited and other one just fell off when I opened up the monitor. So I measured and resoldered them correctly.

So I gotta get a programmer then. any suggestion of which one?

Hi!
We need to update the firmware flash and eprom

How to update the flash the firmware and eprom? I suppose it is not the same as driver update.

Hi

I have a faulty Asus vg248qe monitor which when powered on has no OSD or picture from any of the ports. I see that Windows identifys the display, but thats it. Power button/led is purple, not sure what that means, never seen on other displays.

I opened up and dont see any capacitors being bad or any other visible defects.

Heard it is a common problem with this model, but have not seen any solutions. Anyone dealt with this issue?
