pingooo said:Hello to all, I am a french student so please excuse me for my bad english. (it’s the first time I post here).A few months ago I get a Sony CPD E500E 21'' monitor from a friend and it had the over brightness problem. After reading about the DAS solution on this forum I build a TTL <-> RS232 cable and used an old DOS version of DAS. This version of DAS gave some error message each time I tried to save the EPROM into a file (errors in reading the data). The problem is that I still performed the 'white balance procedur' without knowing anything of the values asked to set. So I adjusted the G2 but get a monitor showing incorrect colours and becoming slightly darker when displaying a white screen.Yesterday I found the howto from P991 DELL SONY (many thanks to him for this great work) and I get to install winDAS and to save my (now bad) EPROM into a file. I tried a second time the white balance with winDAS and the monitor now looks better but still have this problem of becoming darker when showing something white and colours could be better.I want to use this monitor for graphics and video editing and so I want to adjust the white balance exactly. I can get a colorimeter from a friend but I don’t know how to use it with winDAS and what I should do with all this setting winDAS is asking for during the white balance procedure.Perhaps someone (P991 DELL SONY, you said you had performed it for your monitor) can explain to me each step of the 'white balance procedure' from winDAS, how I should set the parameters and what I should measure with the colorimeter. That would be a great help for me.Many many thanks in advance for your help.
P991 DELL SONY said:If you're ready for a complete education, I'd try the navy's NEETS modules. They cover CRTs and other vacume tubes, how caps,resistors,diodes etc. work. After reading it all, you should be more qualified than a repair guy. I've only read the part on CRTs in general.Do you have the service manual for those monitors? That could probably make finding the right things easier.I doubt the G2 can cause a problem, the more resistance, the brighter your screen gets, so it's actually got less voltage on it when it's brighter. Atleast, for that resistor people keep changing. I haven't actually studied the G2 circuit that much. It does seem to be connected to the FBT somehow, in adition to be connected to an IC which is probably controlled by DAS.If you find any specific monitor/tv/CRT repair stuff, let us know.Thanks.
sholodak said:Hi... Many many thanks for everyone's help on the color settings. I picked up the cable from the hobby place, fixed the pinout, and got Windas to lower the G2 voltage on my Sony CPD-E400. The retrace lines are gone and I have a color black again! Two questions though... First, I have 2 Sony CPD-E400's.. one was washed out, the other wasn't. Ideally, the color would match on the two... It's not as easy as loading the data file from the good one onto the bad one by any chance, is it?Also, I'm still having some color issues that I'm trying to work out. The color is excessively blue, not red enough. The Sony Color Test app shows red as having a purplish tone to it. I lowered B_DRV, raised R_DRV... same with the R_CO_MIN and R_CO_MAX and B_CO_MIN and B_CO_MAX... It's still really blue. Whites & grays come out blue, etc. Any idea what settings I should be playing with?Thanks, Scott
gorbash said:hey guys.... i have a Sony E400 with the classic "too bright" problem. I got myself a cable and configured WINDAS as instructed... yet when i when i run WINDAS the error message "No mdl Files" comes up. Also when clicking "model sel" no screen comes up. any ideas?
onebyside said:My 21" inch trinitron has 2 lines across. This is what makes it a "Trinitron".
onebyside said:The no mdl files is normal...I had same prob with the model select not finding anything till I switched to a diff pc, for some reason my main box wouldn't recognize the monitor/com port.rule out what you can, what ever is left is the prob
gorbash said:by "normal" did you mean "common"?? so simply using another computer is the only solution for this "no mdl files" problem??
onebyside said:everytime I start windas I see the "no mdl" files.....the program works
Rilou said:Hi everyone,I received a Sony G500 today. It has the same ugly bright picture described in this thread. Further, the picture seams to be out of focus towards centre. Whenever I change a window to full screen, the monitor picture resizes itself. It scales up and back to normal size as if it is pulsing.My question: Is it worth the money and trouble to make DAS working for my monitor? Can I solve all mentioned issues with that tool?Thanks
SCAR said:are we even TRYING to fix his problem anymore? anyway mine is also too bright. It is really really rich in color though. the white hurts my eyes and the black feels sooooooooo good. i have to turn up the brightness while playing counter-strike and turn it down to trype a document in word or surf the web.EDIT: it's a hyvision 17''
stay said:Need to raise a couple of points.On windows XP SP2 here, so regsvr32.exe resides in the %systemroot%\system32 folder. It's in the path, so "copy msflxgrd.ocx %systemroot%\system32" and "regsvr32 %systemroot%\system32\msflxgrd.ocx" are more appropriate. "%systemroot%\system" isn't in the path on XP by default.After running windas and selecting the appropriate monitor and serial port/mode, windas bombs when attemping to select "Save Data to File".Thankfully, it still remembers the settings you have chosen, and simply restarting windas and going straight to the "Save Data to File" option works fine.Should mention that my E400 shuts the CRT down whilst EPROM reading/writing operations are in progress, usually for 15-30secs, and fires up again once complete.The first time I performed a read operation on the display, i noticed afterwards that the Monitors external controls had ceased to operate!Running windas again and performing another download operation restored the external controls.Anyway, my E400's G2 setting was 106. I dropped it by 4-6 notches each time, testing in-between, and finally settled on 90 as a reasonable figure that gives pretty much a pure black screen in a black room at the user brightness setting of around 30. Much better than the constant 0 setting it had needed before whilst still displaying scanline-retrace during warm-up.
onebyside said:hiHaving a prob getting any response from my dell trin 1130 in Windas. Am I correct thinking that pin 1 is the top pin on the rear port?

Mortalkind said:Thanks to everyone who has contributed to this forum. I have now fixed over 30 Dell P1110 monitors with the Windas solution! Now I was wondering if anyone has a fix for slow warmup times on these monitors? Roughly 1 out of every 5 of these monitors take as long as 85 seconds before a picture is displayed. The warmup time does not seem to be related to the brightness problem since the warmup problem remains after the brightness fix.Has anyone else run into this problem? If there is a lot of interest, then I should probably start a new thread.
Rilou said:If I'd know what 4 pin connector I have to use... and there are certainly a few connectors in that monitor. Thanks for your help!
dellp1130 said:There wasn't a 4 pin connector visible at the back of the monitor but after removing the monitor casing I see a connector that looks like the old floppy drive power connector type connections which is probably what I need to use.
despotic said:Thanks a lot for the detailed info and instructions, P991 DELL SONY!!! I finally managed to fix the brightness issue of my sony G500 without a workaround such as the resistor fix :):):)I'd like to add a note to running WinDAS on WinXP. Make sure to run it as Administrator as I found that I wasn't able to communicate with the monitor as a regular user.Here are a few pics of my kickass cable :) ... was easy to make, thanks gain p991 ... used 1uf 50V capacitors, small breadboard, female db9 connector with an easy clamp, 4-pin connector, and a bunch of wire ... all were purchased @ supremetronic located in downtown toronto, canada: Google Maps Link for under $12CAD (tax included) ... (this price actually included a bunch of resistors in case the windas fix didnt work ...glad I didn;t have to use them since I don't have a soldering iron here).Ok ... here are the pics:Just to add another comment ... I had to edit the .dat file with a hex editor since it couldn't be opened by a text editor properly. Here are screenshots of b4 and after ... (compare light with light stripe and dark with dark stripes ... amazing :)):
mike171562 said:I just did the mod on my Dell P1110. I could on find a 10Mohm 1/4 watt, resister from my local radio shack. So i soldered it in parallel with the existing one. I turned the monitor back on and after about 20 min the color got good and dark. the only problem is when I turn it off for the night and come back in the morning It is bright again and doesnt get dark until it warms up for about 20 min also, it intermintently switches back to bright and then dark again. Does this mean i didnt solder it good enough?
dscharlie said:Hi P991 DELL SONY, I have been going through the instructions on your webpage (thanks!!!), however I am having trouble with the installation of WINDAS.The step where I need to get TransDll.dll RegDll.dll and LimitDll.dll does not appear to work. (I installed astro SG, but it does not dump those files into the windows/system folder).Is there any other place to get these file?Thanks for all the help
