Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
hi, KvnTM right now I'm in front of the card. could you tell me how to set up the tester to take measurements? should I set it to diode or ohm?Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
Depends on what you want to measure.
If you want to measure for shorts or resistance then set it to Ohm
If you want to measure voltage set it to VoltComment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
in the previous post I wrote that pr12 heated a lot and for this reason I removed it. you advised me to test pr12 without resistance to see if it was pc16 in short or the chip.Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
So my card shows up: pr12 Missing c26 Missing c20 missingAttached FilesComment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
Oh yeah I remember.. Put your meter in Ohm mode and put your red probe on the left pad of pr12 and the black probe on either one of those screw holes.Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
nothing ... it gives me some value if I put the red probe on the right ... I put the tester at 200kComment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
I put the tester at 2000 and put the black probe where the screws go and Red probe both to the right and to the left of pr12 but no valueAttached FilesComment

Resistance could be out of range. Measure with 2000k rangeComment

I don't know if it could be strange to me from 480 and slowly it increasesLast edited by antony.ag; 12-03-2019, 08:47 AM.Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
do I have to remove pc16?Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
Could you put the readings and where you probe in the photo? I'm not sure if you are measuring correctly..
My question was if you did anything to the board when the resistor was heating up. I know you removed the resistor but anything else?Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
measured at 2000k and brings me 480 and goes up ... the components removed are only those mentioned before c26 and c20 ... when I removed the resistance I did not remove any other component ... the first component that I had removed was c26 then I removed c20 and afterwards I realized that pr12 burned and I took it off ... I didn't take anything anymoreAttached FilesComment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
how can i proceed? Please :-(Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
ok perfect I will try to do it immediately ... how can I measure the capacitors I need with the tester?Comment

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...
yes thank you very much very kind ... but I had to take them in another motherboard how can I measure if they can go well? because on the cards the value is not marked ... with the tester how can I measure the value of the capacitor that I would like to take from another motherboard?Comment

Hi, This model has bottom mounted leds . Got it with right ride 1/3 of the display black. So I checked the 6 + and - wire that powers 6 different zones and found that the 5th zone was open, which opens 6th zone too makes the right 1/3 of the display dark. Opened it and found one blown led on the 5th zone and shorted that path using solder. So now all the zones works when I check it using the bl tester , but when I put everything back together there is no backlight! The voltage I am getting when neg to chassis is 387v. How does that happen? Still individual zones working with bl tester .

Hello , for some time I was studying Quanta U9x/8x schematics and the option to use both type of screen (LVDS 40 pin / eDP 30 pin).
In some cases to use LVDS screen PCB use converter IC RTD2132/6
Now I found an HP 15 F series U99 mainboard with RTD chip not populated and LVDS 40 pin lcd touch screen
at the same time I have another HP 15 N series with Quanta U92 mainboard and RTD2136 with eDP 30 pin lcd screen (no touch).
Maybe someone more experienced in the subject can clarify if is posible to change type of screen used with some resistors / bios options change.

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.
When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it... -
Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM
