Monitors powers on to a white screen and makes a hissing and then static noise until it goes into standby mode. All caps look visually okay but are su'scon brand. Do you think recapping will fix? I am not so sure. Any other ideas? I have reseated the ribbon cables.

Check reading of voltages.
Check the unit connected to a good computer so it can get signal and don't have to go into standby.
Check also if the hiss comes from the top or bottom of the LCD. It might be a broken/arcing CCFL.There are 10 kind of people in this world: those that understand binary, and those who don't.- ASUS ROG Maximus IX Code

Re: Emachines le1938
Did you check if the noise was produced on the top or bottom of the LCD panel? Again, I think you have an arcing CCFL in that panel.Originally posted by IRShiftyThere are 10 kind of people in this world: those that understand binary, and those who don't.- ASUS ROG Maximus IX Code

Re: Emachines le1938
I observed the noise while the panel was apart, but I was listening from the top of the panel.Originally posted by eguevaraeComment

Re: Emachines le1938
I don't know if this applies to your case, but here I go .....Originally posted by IRShifty
I just repaired a Sony VAIO Laptop that had the following problem: It sometimes didn't have any problem, but sometimes it just turned off (backlight only). After further inspection I found out that a noise came from the bottom of the panel. It turned out that the CCFL was loose and the noise was producing by voltage arcing to the metal rail/shield that normally protects the lamp and reflect the light. The guy didn't allow me to change only the CCFL (why, I don't know...) and in the end changed the panel. But the problem could be your case too. Again, if the panel is apart, check if the sound come from the bottom or the top parts. If a CCFL arcs, the inverter will shut off.
If you want to test if the lamps are the problem, take the panel from your Samsung on the other thread and connect it (lamps) to this inverter. If the boards are OK the panel should light without the noise.
As for the all white screen, it may be the fuse at the input of the LCD panel.There are 10 kind of people in this world: those that understand binary, and those who don't.- ASUS ROG Maximus IX Code

Hello,
I know that this is probably a long shot, but I figured if anyone could find this BIOS, it would be you guys.
I am working on an (old) eMachines T6520 desktop PC that might have a corrupt BIOS.
Model:
eMachines T6520
Motherboard markings:
MS-7145B0505068731
RS480M
7145 v2.1 RS480-A21+SB400-A23
Symptoms:
The computer does power on, CPU fan spins, but does not POST. No display.
Troubleshooting steps so far:
Replaced the CMOS battery (which was in need of replacing)
Re-seating... -

I've been using this monitor for last few years.
Symptom started by OSD menu popping on and off randomly by itself. So i tried to clean the touch control area with some cloth but it didn't help.
After 20 minutes monitor started hissing from the back. And then 30-40 seconds later screen started fade off/on like as if i was turning down the brightness that's when i turned it off by power button (hissing stops) and replaced it with spare monitor.
Today i opened up the monitor, excited to repair my first monitor (or big electronics) hoping it's a bad... -
I decided to see what kind of "sleeper" build I could do on the Emachines T3104 from cheep/free thread with the "random junk" I had laying around (with the exception of a SATA to IDE adaptor I bought to make the original Emachines optical drive to work).
Before:
Specs:
Motherboard: FIC K8M-800M
CPU: AMD Sempron 3100+
RAM: 512MB DDR-400 (2x256MB)
GPU: Integrated VIA Unichrome Pro
PSU: HiPro HP-P3527F3 300W
HDD: None/removed (case sticker indicates it originally had a 100GB IDE HDD)
ODD: Lite-On DVD-ROM/CD-RW...
