New Net City screen turned blue

[chacal231077]

hi!


Small problem the screen of my terminal after a game change with a period of 4 hours the image has become blue.

I tested other system same result

The VGA Cable is new.

I tried a reset of the settings nothing changes even with the Extend menu

Thanks for your help

I dunno how to fix it, but looks like your GREEN went out.

My guess, the green color transistor/circuit went out. Let's hope it isn't your green gun.

Could be something simple too, like the new VGA cable is bad. Test it on another video setup.

Hi Here is the news Sorry for my english not very correct :/ I tried another VGA cable, it's the same problem .

I decided to redo a large part of the Neckboard & Toshiba PD1843 for the welds.Clean up any excess Flux originally.

I'm also going to change the RGB amp. I would do a Capkit at the same time.I

unsoldered this little PCB I do not know what it is for ?





I'm also on an Arcade Repair Group on Facebook.I talked about my configuration problem in memory of my settings.Because the PD1843 board no longer keeps the settings in memory with the original remote control .Only the Extended Menu Remote keeps these settings.I put a photo of an NEC chip that I did not know One of the members said that the chip was the AVR microcontrollers custom chip .Toshiba D29C051 Monitor manual/circuit diagram
