What is the part number of that 4 legged chip next to c66 on the backside?

Re: WestingHouse L2210NW Will not power.
Most inverter boards that I have seen have at least 2 transformers driving the CCFLs. Yours only has the 1.Leave a comment:

Re: WestingHouse L2210NW Will not power.
It is best to get the same because I'm not sure how a 17 inch length CCFL tube will react in a 22 inch monitor. If the connector, voltage, and current are the same, it shouldn't be a problem.Leave a comment:

Re: WestingHouse L2210NW Will not power.
also there is another transformer on the board as well should i get the readings from that one as well?Leave a comment:

Re: WestingHouse L2210NW Will not power.
would any monitor work or does it have to be the same one? cus i have a 17 inch hp monitor just saying aroundLeave a comment:

I just realized that no one including myself asked if you can still see the video/image if you shine a flashlight on the screen? Please answer.Leave a comment:

Re: WestingHouse L2210NW Will not power.
Do you have another monitor where you can do the CCFL test?Leave a comment:

Re: WestingHouse L2210NW Will not power.
Hi sorry to butt in but this board apart from maybe the pins that connect to the logic board
is the same as the board they use in the acer 1916 maybe another to look at for spares or comparisonLeave a comment:

Re: WestingHouse L2210NW Will not power.
The 1 should show up on the left hand side of the multimeter display.
Many newbies seem to confuse 1.0 ohms (on the right hand side of the display) with 1 (on the left to indicate out of range). My meter says 0L to let you know it is out of range. So if you interpreted 1 (on the left) has 1.0 ohms, I can see how you thought this transistor was shorted.
stpf1020ct measurements:
1) red on pin 1, black on pin 2. -1.
2) black on pin 1, red on pin 2. -1.
3) red on pin 3, black on pin 2. -1.
4) black on pin 3, red on pin 2. 1.
I suggest if you still have 1 second to black that you move onto checking the CCFLs and tranformers.Leave a comment:

with the mastech
SET TO 200 .7 when touched red and black probes together

Re: WestingHouse L2210NW Will not power.
I'm sure the mastech will be way better. I hate to ask, but please redo ALL your measurements again. I have no faith in the DT-830b readings (I have one and it is busted).
It shouldn't take you more than 5 minutes to remeasure. Please post results including the reading when you touch the two probes together (this is your baseline/calibration).Leave a comment:

Re: WestingHouse L2210NW Will not power.
See that arrow symbol (in the red box) just right of the 200 ohm? That is your diode test function. Please retest the diodes with that function. Or are the results in post #32 done with the diode test?
BTW, I have that exact same multimeter. It is absolute crap. I got a different one.
Question: After you test the diode in diode setting functionality, switch it back to 200 ohms and touch the red and black probe together. What reading do you get?Last edited by retiredcaps; 08-21-2010, 05:31 PM.Leave a comment:

Re: WestingHouse L2210NW Will not power.
ok i retested the transistor com 1 and red 3 and it came back 1 at 200ohms
sbf1060ct measurements:
1) red on pin 1, black on pin 2. 130
2) black on pin 1, red on pin 2. numbers seem to keeps going up with out stop
3) red on pin 3, black on pin 2. 129
4) black on pin 3, red on pin 2. numbers seem to keeps going up with out stop
stpf1020ct measurements:
1) red on pin 1, black on pin 2. 419
2) black on pin 1, red on pin 2. numbers seem to keeps going up with out stop
3) red on pin 3, black on pin 2. numbers seem to keeps going up with out stop
4) black on pin 3, red on pin 2. just shows a 1 on the left sideLeave a comment:

Re: WestingHouse L2210NW Will not power.
What is the make and model number of your multimeter? For example, you might answer Craftsman model 34555.
For the transistor test, just choose the 200 ohm setting and leave it there. Retest pin 1 to pin 3. If it reads 1 on the left hand side, the multimeter is telling you the resistance is > 200 ohms. If it really reads 10.2 ohms, it is shorted.
For the diode tests, choose the diode setting on your multimeter. It will look like an arrow pointing to the right. Once you find it, retest the diodes.Leave a comment:

Re: WestingHouse L2210NW Will not power.
sbf1060ct and stpf1020ct measurements look good. The reason you get a resistance that constantly goes up is because your meter is charging the electrolytic capacitors.
Also, if your meter doesn't have a diode/continuity test, use the 2000 Ohm scale only to test diodes. Out of circuit, a good diode will test between 100 and 1000 Ohms one way and appear open circuit the other way. A bad diode will show close to 0 ohms (short circuit) in both directions.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.

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... -
