k3114 measurements:
com pin 1 red pin 2= meter doesnt change from 1 also cycled through different ohms 2000k -200
com pin 1 red pin 3= meter set to 20kohm reads 10.02
com pin 2 red pin 3= meter builds up and doesnt cap out even on 2000k ohms
sbf1060ct measurements:
1) red on pin 1, black on pin 2. meter set to 20k and numbers seem to keeps going up with out stop
2) black on pin 1, red on pin 2. meter set to 20k and numbers seem to keeps going up with out stop
3) red on pin 3, black on pin 2. meter set to 20k and numbers seem to keeps going up with out stop
4) black on pin 3, red on pin 2. meter set to 20k and numbers seem to keeps going up with out stop

Re: WestingHouse L2210NW Will not power.
To properly test them, do this. pin 2 is center pin.
Put your multimeter on diode test.
1) red on pin 1, black on pin 2. Record/report diode measurement.
2) black on pin 1, red on pin 2. Record/report diode measurement.
3) red on pin 3, black on pin 2. Record/report diode measurement.
4) black on pin 3, red on pin 2. Record/report diode measurement.
Do the same for the other diode.
Report measurements and we will tell you if they are bad or not.
Just to doublecheck, what ohm measurements did you get on the bad transisotr (k3113)?Leave a comment:

Re: WestingHouse L2210NW Will not power.
thanks! sorry im new this type of work. ive replaced 100's of caps but i have no clue how to find transistors and transformers ill remove those transistors asapLeave a comment:

Re: WestingHouse L2210NW Will not power.
Can you tell it is cracked or does it look cracked?
Well, IF it is actually cracked, this is the closest replacement I can find.
http://lcdparts.net/TransformerDetai...ProductID=2775
It is not an exact replacement, but you can email them and ask if they have unlisted stock or something?
Your best bet may be to replace the shorted transistors, try the monitor and if it still fails, try to find a new transformer.Leave a comment:

Re: WestingHouse L2210NW Will not power.
so after googling the numbers on the transformer i cant seem to find anything to replace it.
tk 430k 101-821061
--02
thats all the markings i could find on the transformer.Leave a comment:

Re: WestingHouse L2210NW Will not power.
Thats what i thought but didnt want to switch up the names. But as i look at it further that black line looks like a crack, im assuming that if it is it would cause some major problems correct?Leave a comment:

Re: WestingHouse L2210NW Will not power.
So while i was doing the tests it looks like two of the transistors are shorted out. I have the part numbers and ive been looking on the internet now how to find them but so far im at a loss the information on these transistors is:
nec k3113 82ks13
lt 8217 sbf1060ct
lt 8216 stpf1020ct
http://pdf1.alldatasheet.com/datashe.../2SK3113B.html
For the last 2, I'll need a close up picture to id them.
If you measured them in circuit and found them shorted, remove them and retest them out of circuit to confirm they are shorted. You will have to remove them anyways for the replacements. Just take a picture or mark up the board so you remember which way they are installed.Leave a comment:

Re: WestingHouse L2210NW Will not power.
Thank you so much for the link to the tutorial on how to test the board a little more then i knew how. So while i was doing the tests it looks like two of the transistors are shorted out. I have the part numbers and ive been looking on the internet now how to find them but so far im at a loss the information on these transistors is:
nec k3113 82ks13

Re: WestingHouse L2210NW Will not power.
Hi i have a L2210NW and it powers on and shows video for a second then the screen goes blank. ive taken it apart and looked at the caps and they all look fine. i havnt tested them with a volt meter or anything cus im not sure exactly how to do that. Does anyone know if perhaps the caps arnt the main cause for this issue?Leave a comment:

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.

TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

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... -
