I found the board on shopjimmy.com for $29, but I question the legitimacy of the site.
WestingHouse L2210NW Will not power.

Re: WestingHouse L2210NW Will not power.
So, upon looking at the power board, it's just pretty much totally screwed. There are a couple of parts that are physically broken (snapped) and I'm just going to get a new power board off of eBay for $50.
Does anyone maybe have a better recommendation for where to get this power board?
It's a DAC-19M020 AF.
Thanks again.Leave a comment:

So, I have a multimeter, but I have no idea what settings to put it on to test the big cap (because I'm a noobie, I've just fixed some easy to solder components in the past). I also don't know what setting to use for the logic card connector pins.
As far as what I have tested: My patience in opening up this monitor (held together by tape instead of screws, I'm totally not joking) and that's about it =(
Sorry for my lack of knowledge, but thanks for the help =)

Originally posted by questionmark425Okay, here are some pictures. The discoloration appears to be minor, but that is just my opinion. you can see that there are two capacitors that are slightly swolen, and I was mistaken about the brand, it is Samxon.
Also, one of the capacitors solder points is about 1mm away from another trace, I'm worried I might mess that up with a solder job.
Let me know what you think.
It's late, I'm going to be lazy and just describe what I want tested. If I'm not clear, let me know and I'll mark up some pictures. I'd prefer you didn't electrocute yourself.
1. CAREFULLY measure the voltage across the very large cap with the AC connected. It should be about 1.4 x the AC voltage.
2. At the connector to the logic card, measure the voltage from each pin to ground.

Re: WestingHouse L2210NW Will not power.
Yeah, I'll pick up some caps and give that a shot. They are CapXon caps, so even if that wasn't the issue, since I already busted the monitor open I should probably replace all of those regardless.
I'm mostly just hoping that it isn't the "Touch Controls" that went out.
I'm probably not going to get much farther without pics, and I'll post those in about 4 hours. Just wanted to see if the thread could get a little attention =).
Thanks for the reply =)Leave a comment:

Originally posted by questionmark425So, there I have a Westinghouse L2210NW 22" Monitor that will not power on. It has the "Touch control" buttons, so all of the monitors controls (including power) are of a capacitive touch nature, so I'm hoping this didn't go out on me.
When plugging in the monitor, I can hear a high pitched noise emitting from it (had a similar symptom with a Gateway 22" monitor, turned out to be a bad cap).
I dissembled the unit and saw that the power board had 2 or 3 capacitors that were slightly swolen (the vent had not broken, they were just bowed out a millimeter or two). But the PCB was also discolored near the AC power jack (Not dark brown burned level discolored, just a little browned.) However, all of the solder points and traces on the board appear to be undamaged.
I don't have pictures to post right now, but I will be able to post them later today. I was just wondering if anyone had experience with a discolored power board, and if it was a cause of failure. And also to ask if a capacitor is silghtly swolen, and the vents are not broken, do you think that they have been struck by the plague? Or should they still function at that point.
Just seeing if it's worth throwing $10 in caps into it, or if I should buy a new power board entirely.
One point; sometimes the problem with the power jack isn't the solder joint to the circuit board. The standard assembly technique is to rivet the center post through the plastic housing and into the tab that gets soldered to the circuit board. If the plastic gets hot or shrinks the center post no longer makes good contact to the tab and you have an erratic connection.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

by PantherDaveHi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

by sam_sam_samI have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
