Re: is this a NCP1014AP065G ?
from the datasheet - yes.
all variants are AP,
ending values are 06, 10 or 13.
clearly this is 06. -
Re: is this a NCP1014AP065G ?
nice one . just needed confirmation ... its from my tv power supply . main capacitor open circuit . suppose thats what killed it ? quick check of diodes etc nothing else appears shorted .Comment

Re: is this a NCP1014AP065G ?
Getting a bit o/t, but if your TV PSU has Active PFC (APFC), you might want to make sure that circuit is running as it should be and not overshooting. Main capacitor going open-circuit can be attribute to either bad part (crap cap brand) or APFC overshooting and killing the cap over time. Usually it's #1, but I've seen the latter wreck even good quality brands too. Something to keep in mind after replacing the main capacitor and that NCP1014 chip.Comment

Re: is this a NCP1014AP065G ?
there are 2 bulged caps on the board i am replacing as well .
bit of history .tv always worked well but would sometimes forget what source was selected when coming out of standby .. i had been away a week and on my return i plugged the tv back in and no standby . grabbed the hair dryer and warmed it up .stand by light come on and switched on fine .left it on and ok for first night . next night it was off when i woke up . no standby light . so far found this ic blown up . 2 bulged 4700uf 6.3v caps and main 150uf 450v cap open . plus a blackened open fuse .
open cap is a capxonLast edited by petehall347; 09-28-2018, 04:27 AM.Comment

Re: is this a NCP1014AP065G ?
well its up and running . replaced 4 caps in all plus the ic . tv starts up in 4 seconds .
main filter cap replaced with 150uF 450v SNAP-IN, Rubycon (JAPAN) HXG 105C, ripple:1.51A! LIFE 3000HrsComment

Re: is this a NCP1014AP065G ?
Glad to hear you got it running again.
By the way, do you have a picture of the PSU board? I'm just curious if this TV has APFC or not, given the 450V primary input cap. Thanks.

Re: is this a NCP1014AP065G ?
sorry its back together .. tv is an odd one locally built . evesham computers was one of their company names . think they are out of business now . hold on might have got a pic will check the phone .
edit ..sorry only a pic of chip . i did have a tab open with same one but long closed it . will see if in historyLast edited by petehall347; 10-07-2018, 05:35 PM.Comment

Hi folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
HP Modelnumber: 14-dh0061nb
This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
All these 3 batteries are charging... -
Hey everyone,
I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components... -
Hey everyone,
I just went ahead and unscrewed a faulty GTX 980 TI from Gigabyte. What I found beneath the cooler was, as it seems, a common issue of that card. Two blown fuses on the bottom right corner of the card next to a MOSFET.
Now my question would be if there is any schematics of that card available to figure out which are the blown components so I can try and replace them together with the mosfet if needed.
Find some pictures of the actual GPU together with a picture of how it should look like.
I also wonder whther it might be a problem that there... -
This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...
