As a matter of fact, I tend to read posts aloud to practice my English (2nd language) and see where punctuation can be inserted and such,so I can both try to help, learn and also improve my language.... you should try to read it....There are 10 kind of people in this world: those that understand binary, and those who don't.- ASUS ROG Maximus IX Code

Re: Issue with Westinghouse 19" LCD Monitor (large pics)
Hello,although this post was started several years ago, it still keeps alive, so, after reading the whole tread, I think I can help a little.
When trying to fix an ACER 2017, I used this dac-19m005 datasheet I found on the web.
http://www.megaupload.com/?d=YJWEDABQ
Here you can see schematics and components. Although it is a different LCD model, is has the same power board: DAC-19M005 CF REV: 00A, (plus it has just DUB conector, no DVI, but still the same board too), so: same problems and same fixes, I guest.
After recapping all (same 2 bulged caps as every faulty board), I can see images on the screen but no backlight. You only can see it taking a light close to the screen ( I didn´t read anybody in this situation, everybody has no light but nobody has mentioned about dark images with no backlight)
All the fuses on the backside are OK but I can see a damage transistor: Q204, on the backside, right close to the F200 4A fuse, so probably this is what I need to fix.
According to Kahless (on post #299 and # 301) and billy 66 ( #320) I can see Q2004 burnt ( probably that´s because F200 fuse didn´t blew up), but I checked R210 and I got about 11 Ohm, so I think it´s Ok. Anyway, I ordered replacements for the whole components:Q204,Q208 and R210.
I´ll post the results when I get it working here or in a new thread refering ACER 2017 (only DUB, no DVI conector)
ThanksLast edited by blackrider1; 05-12-2011, 11:34 AM.Comment

by CuboyHello,
I am currently trying to help a ONG by volunteering to help repair laptops, it's something that i have been into since 2017, always watching videos, on discords, forums etc...
I have an HP ProBook 4510s laptop that does not power on and has no indicator lights, which suggests an issue with the power supply or the motherboard.
I started by verifying that there is voltage at the input of the motherboard, confirming that the power adapter is working correctly. However, when I checked the voltage at the output of the first MOSFET (Q1032), I found 19V at... -
by ebyte64Good day everyone.
I have been scratching my head with a Lenovo laptop I got in today.
The laptop had no power and taking no amps from the power supply. Checking voltage showed 20v only on one side of the first mosfet. Took it off and replaced it and then same story. Took off second mosfet and then the first mosfet had the right voltages as well as 25v on gate is it should. Replacing the second mosfet the problem started again.
Even using a wire to bypass the second mosfet does the same interference with the first mosfet.
Would anyone... -
by JaneI tried to use this method:
Testing an N-channel MOSFET:
Step 1: Discharge the Gate (turn off the MOSFET)
Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.
Step 2: Charge the Gate (turn on the MOSFET)
Now, place the red probe on the Gate (G) and the black probe on the...09-27-2024, 03:31 AM -
by momakaHere's another LCD monitor repair: Westinghouse L2210NW.
Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)
I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

by NooyHello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:
I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet... - Loading...
