The software was obtained with the help of a previous poster (deesto). The software needs a bit of reverse-engineering if you know what I mean, to get past the security key. If you use the software, be sure to install the ActiveX Flexgrid control and register it, or the mdl files will be inaccessable. The resistor in my monitor is 2.2M just as it should be. The feedback/reference resistors all check to be the proper values also. Rather than change this resistor as has been suggested, I can connect a resistor of 1.5M from the CRT G2 point to ground and the voltage lowers to an acceptable range and monitor looks great (except for the bit of covergence at the sides). At this point it is still a mystery as to why all of these monitors seem to have the same failure, but eeproms are not the most reliable components. They have been known as a high failure rate part. Many RCA televisions using adjustment data in eeproms have had a very high failure rate (if you had a newer "dead" RCA television chances were that the eeprom was bad). When (if) I get this working, it will be interesting to find if the eeprom has actually failed or the data has changed.
Yes I did. I can adjust all parameters available under digital control. I can adjust G2 voltage via setting the proper value to the PWM. Feel free to contact me for more information.
So nobody actually knows if the entire range manufactured from 1999 to 2002? have this problem, Im going to buy a post 2000 model but not if its gonna have this fault.
My Dell P1110 has EPROM date 9-2001, and it has the opposite problem (too dark)! Apparently I'm the only poster in this thread who is in this category.
If your screen is too dark, then maybe your G2 is too low. Do you have a way to measure it (100-600v)? Be aware input impedence of meter would affect the reading. How about your filament voltage? ...
Xweebie, are you going to post the schematics for the cable?
it seems the only resistor that i can find locally is a 10m ohm 1/4w from radio shack. is that ok for the fix?
They show 2 watt, 500V, 2% tolerance resistors on the following page:http://www.action-electronics.com/resist2w.htm
Only $1 per resistor, and USPS shipping for $3.90. They don't guarantee to have them all in stock, but the price can't be beat... and the 500V, 2W ratings beat the other resistors which I see in this thread.
Sizes shown for the 'replacement approach' include 4.7M, 5.1, 5.6, 6.2, and 6.8M.
I just put in an order for the 'put another in parallel on the top side' approach. My monitor is quite washed out, so I'm going with the 16M resistor (for a net resistance of slightly less than 6.2). I'll let you all know if/when it shows up, or if I have to switch to a different (in-stock) size.
For the resistor mod, should one be using 1/4w resistors or 1w ?
