Hi,

It fixed it for me.
Cheers!

Hello, Thanks to REpairAT I was able to boot an LM94Q/34UM95/EAX65360303 (1.0).

Does anyone have version LM94Q/34UM95/EAX65360303 (1.0) here? I don't know if the EAX65360306 version causes any problems to my EAX65360303 monitor, thanks

Hi there, new user here!

Just wanted to say that I also got my monitor working by flashing ROM file posted here!
I downloaded the file, hooked up CH341a directly on to the chip on the board without desoldering it, flashed, and it is working now!

Thanks!

Could you describe/provide a diagram of how you connected CH341a to IC205 (mx25l8006em2i-12g) ?

Does anyone have a dump file for the LG34UM88-P? Or advice on where to find it? I tried flashing with the UM95 at the top of this thread but no luck restoring the monitor yet. On my board it appears that IC202 is the EEPROM. Thanks for any insight!

Does anybody have a clue what could be the problem, left and right side of the monitor sometimes are not syncronised, and it is only noticed on moving picture. I 've repaired this monitor with flash dump couple months ago, and it works, but sometimes i get asyncronised left and right side.

Video at youtube I uploaded in slow motion: https://www.youtube.com/watch?v=fgUwzhhSpKQ

Dose anyone have an idea about what is going on in the video that this person posted because I curious about what could cause this particular issue

This dump helped me get my monitor turned on. Now I have the issue of everything except for the OSD looking garbled. I even get these lines with no signal.

Is it possible that having the wrong firmware (I don't have thunderbolt) is causing this, or is this a problem with something else like the scaler chip?

To answer my own question my problem was with the ic700 voltage regulator. That tiny thing was a struggle and it took me three tries to get a replacement soldered in correctly.

I shorted the original with my multimeter probes. The second put out 1.9v when monitor was off but dropped to 1.3v on. Third I cooked soldering in place. 4th finally worked

I'm not sure why I'm so astounded that the internet is helpful, but this is the best thing that's happened to me in awhile. I never realized how much I like this monitor before it wouldn't turn on.

I had a bit of trouble getting the clip to attach. It took me 5 or 6 worrisome tries before the MX25L8006E was detected. I used the binary from the zip in post #3.

FWIW, the SPI EEPROM on my board wasn't completely dead and flashrom (under Ubuntu 20.04) was able to read the contents. There was enough info to notice that the original binary contained source code files from July 30, 2014 while the binary in post #3 contained source code files from Jan 17, 2014, so it's not the latest version. Not a big deal. My monitor is back working.

Thanks all!
