Re: Dell E228WFPC goes dim after 10 minutes, not 2 seconds
Wow...I'd almost forgotten about this. Glad someone else could make some use of it!

Re: Dell E228WFPC goes dim after 10 minutes, not 2 seconds
Ugh, problems though.. Monitor was working great after the C806 reflow.. then I put it all back together and now the lower 2/3rds of the monitor aren't working
They are lighter than the top 3rd which makes me think the LCD row drivers now have an issue? What the hell could I have done wrong? I've disassembled the whole thing again and now I'm to my wits end, this monitor is about ready to go to the trash can

You say you shoved the IC around, Have you created any bridges etc?Ugh, problems though.. Monitor was working great after the C806 reflow.. then I put it all back together and now the lower 2/3rds of the monitor aren't working

Just adding flux and reflow without moving it around is enough btwComment

Hi 1supertech,
Would you please give a little more detail on c706. I can't locate it on the main board of my E228WFPC (yes,"C").
Has the matter of c706 in relation to this unit already been discussed? I was unsuccessful with a forum search.
Thanks much,

Re: Dell E228WFPC goes dim after 10 minutes, not 2 seconds
I just found one of these monitors in the trash yesterday and it had this same issue. I removed C806 and tacked on a 1uf 50V electrolytic (neg on the pad that connects to D812) since that is what I had. The monitor is working now. Thanks for the help.Comment

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi all,
I have recently picked up this Dell OEM Nvidia GTX 750Ti 2GB Video card. Its an old card I know but still wanted to get it working if possible. The problem is the following:
- Put the card in my testing motherboard and start running Heaven benchmark
- Benchmarks seems to run smoothly up until half way then the motherboard completely shuts off immediately
- Try to start it again and I get a slight move from the PSU fan - a clear short
- A little troubleshooting later I find one shorted Mosfet - Replace them both - short is gone
- Put the... -
Hello everyone!
Motherboard model: FDI55 LA-J081P
Today a customer delivered this laptop completely dead, with the original power supply shorting when plugged into the connector.
I found and replaced a shorted MOSFET (PQZ3).
Now the laptop turns on (fan runs fine but no video signal) and after 5 seconds it turns off.
BIOS has already been updated (both 64MB and 128MB IC)
+3VALW and +5VALW are still present.
+VCCIN = 1.8V stable (measured on PLZ1 at power up)
Abnormal readings:
PLZ1 to GND = 0 Ohm
PLZ2 to GND = 0 Ohm

Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
Hi all need some help, I've got a Dell insprion 15 3542 that turns on works for about 30 seconds or sometimes a minute or two and then turns off and wont turn on again until I remove and replug the power connector
Not heat related, everything is ok regarding to that.
All voltages are present.
Wondering if this as anything to do with one wire circuit, the charger is not original, but it was working fine
Motherboard is Cedar 13269-1 F3XMC Rev A00...
