If geeks love it, we’re on it
You found the friendliest gaming & tech geeks around. Say hello!
Some differences are normal depending on the age of the parts. One thing's for sure though: With the drift correct circuit removed, both monitors are going to start up at exactly the same brightness. Taking a few minutes to warm up and stabilize is normal, and it's inherent to all CRT displays.With my P1110 for instance, if it's been really cold (i've been out all day today), black appears slightly green at startup and hence the picture appears brighter. This normalizes in less than 10 minutes - that's lots better than having brightness drift for 2 hours.For the second monitor, you may have a problem with the power supply but it's likely something simple like a cold solder joint. I'd try and touch up the soldering, specifically all the joints around the CRT neck, all big semiconductors and relays.Since you will have to up G2 quite a bit after eliminating the drift correct circuit, make sure you adjust it so optimal picture is at 50% brightness or below. I've talked about it sometime earlier, these monitors are wired to automatically lower the contrast when you up the brightness past 50%, to keep focus in check. Trouble is, this also shifts the color balance a bit, which is annoying. Better avoid it by setting G2 so that picture is bright enough before you reach 50% brightness in the menu.Also i'm not sure anyone has mentioned this before: Always remove the ECS cable from the monitor when you're done with WinDAS. Keeping it in causes interference with the 5v rail which shows as slight wobbles in horizontal size.
Ya'll should fix my P1130. Still works, but you can see jittering in text and small lines.
(Was for running classic games on, but I can't look at CRTs anymore, too much eye damage done, strain is too much now.)
Don't think you asked about location... it might just happen that i live on the other side of the world and shipping would be thru the roof. I live in Bucharest, Romania.
the screen blinks bright blue and then the image becomes yellow (like the color temperature was set to "low") for a few minutes. Probably some bad connection (or a short) somewhere,
Another problem is that if it is colder in the room then the monitor takes about a minute to warm up and show picture. On the other hand, if the room temperature is 36 degrees C, the monitor displays picture almost immediately
1. Abnormal G2 voltage, usually 100V~ higher than its original spec at 522V. The G2 voltage can be bring down by modifying relevant value with WINDAS, and after the tweaking, overall brightness level can indeed be lowered. The cause of this phenomenon is still unclear – some people believe it’s caused by EEPROM data corruption, which I seriously doubt: data corruption in ROM is usually random, so why it’s always the G2 value suffer the loss?
2. The picture is over-bright, a little greenish on black at startup and after a while (15-20 minutes or so) the picture become darker, its color more saturated and able to maintain correct black & white balance. Some people claim that brings down G2 back to normal will cure everything, but it’s not true. Although after proper adjustment (for my unit, the G2 value was tweaked from 157 to 126, set at 30 in OSD for brightness) the monitor’s brightness level may be in normal range even the moment after a cold start, but the tendency (darker and deeper over time) is still the same, while the G2 is actually stable all the time.
