Hello,
would someone kindly tell me if the TV panel has dead pixels problem?
I attached the photo, if you zoom it you can see the several dots...
Thanks in advance

I think not, because I read with the digital multimeter between anode/catode 0.217v

Hi William1967,
thanks for your reply.
I have done some readings, please see the attached pic
I think the primarie power supply is working....Leave a comment:

Philips TV 37pfl5604h/12 no standby voltage
[ATTACH=JSON]{"data-align":"none","data-size":"medium","data-attachmentid":3503186}[/ATTACH]
Hello,
I have a problem with this TV, the standby voltage is not present. I have checked the components around the IC fsq510's area and they seem to work, also replaced this IC but the problem persists.
These are the voltages in some pins of IC fsq510:
Vcc=18v
D=320v
Vstr=154v
Unfortunately, I couldn't find the schematic
What else could I check?
Is it possible to provide standby voltage from an... -
Re: Acer V5-551G no power on
I've noticed that on power switch there aren't 3.3v and i think the switch have some problem.
Can't find on motherboard R124 o C156 that are connected with power switch... Jumpered CN10 pin 24 (NBSWON#) to ground and the laptop starts on
, but the PL6 and PL7 and GPU chip becomes very hot. After 15 minutes the display goes off 
Is it possible there is a GPU problem?
Injected 1v to PL6 it absorb 1.4A...Last edited by Bad_IC; 11-19-2022, 04:57 AM.Leave a comment:

Re: Acer V5-551G no power on
i've Checked caps:
PC52→ 3,3v
PC46→ 5V
thanks...Leave a comment:

Re: Acer V5-551G no power on
Thanks for your reply,
On pin 1 of PQ25 there are 0V and it is connected with BIOS pin 8.
On Pin 3 of PQ25 there are 3.3v...
I've found only
PQ33 drain 3.3v source 0V
PQ23 drain 5.10V source 0V
PQ24 drain 5.10V source 0V
PQ13/14/15 all pins 2 to 9.2v all pins 1 and 3 to ground
PQ16 pin 0?→ 9.2v and continuity to ground ? When check continuity to ground the motherboard led 1 switches on. Is there a problem on PQ16, can be shorted?
Thanks...Last edited by Bad_IC; 11-18-2022, 05:24 AM.Leave a comment:

Acer V5-551G no power on
Hello,
I have an Acer V5-551G that not powering on, motherboard DA0ZRPMB6C0
PU6:
Pin 16 VIN→19.4V
Pin 11→ 3.3V Pin 20→ 5V
Pin 23 (pgood)→ 0.036V
I've checked 3.3v always on on PL5 and it's ok, and 5v on PL4 ok.
No 3.3V on the power on button...
On the BIOS chip (25Q32Q8SIG) pin 8 no volt.
Checked continuity between bios pin 8 and 3.3V (PL5 inductor) but no continuity...
How is it possible?
Can someone give me some help?
Can i check something else?
Thanks in advance....Last edited by Bad_IC; 11-17-2022, 05:19 AM. -
Re: HP pavilion 17-e101sl motherboard no turning on
Thank you so much for your time and your valuable advice. I'm very busy now, if i get the chance to replace the SIO, i'll let you know.Thanks.Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
pin37 ECRST→3.35V
pin76 AC_IN→3V
pin95 RSMRST→0V
pin93 EC_PWROK→0V
pin14 HWPG→0V
When power switch button is pressed:
NBSWON→from 3.36V to 0.00V
DNBSWON→remains to 0V nothing happens
Power supply consumption:
from 0.02A to 0.04A when power switch button is pressed.Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
LIDSW→3.35V (please see attached pic)
Removed the power switch board, EMU_LID (pin25 SIO)→0V (see pic)...Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
pin25 EMU_LID→0V
pin127 LID_EC#→3.37V
J1→2.36V
J2→0V
I've Checked capacitor c905 on RTC section and it is short to ground; checked the same cap on the spare motherboard and it is no short.
I think that c905 is damaged and i have to replace it.
ok, replaced c905, now the readings are:
J1→2.64v
j2→2.64v
but the motherboard doesn't power on.Last edited by Bad_IC; 09-02-2021, 10:30 AM.Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
Sorry, but i can't locate LIDSW pin on SIO.
Dc jack is stable and glowing. On off state the consumption is 0.02 Amps, when I try to turn on it is 0.04 Amps. How can i check the RTC circuit?
I've attached some pics....Last edited by Bad_IC; 09-01-2021, 04:32 AM.Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
Hi mcplslg123,
I've replaced PU6 with a new one, but the motherboard doesn't power on.
Checked PU6 pins but the voltages are as the previous:
PU6
pin20 →19.5v
pin15 →0v
pin13 →12.3v
PU5
pin20 →19.7v
pin4 → 25.4v
pin5 → 3v
pin16 →6v

Re: HP pavilion 17-e101sl motherboard no turning on
Ok.
I've bought the new pu6 (g5934).I'll let you know as soon as I get and replace it.
Thanks.Leave a comment:

Re: HP pavilion 17-e101sl motherboard no turning on
I've another identical motherboard just for spare parts that powers on and checked:
PU6
pin15 →0v
PU5
pin5 → 3v
pin16 →6.05v
Those voltages are the same on the motherboard that won't power on.
Have I to replace PU6?Last edited by Bad_IC; 08-07-2021, 08:31 AM.Leave a comment:

HP pavilion 17-e101sl motherboard no turning on
Laptop Hp: 17-e101sl
motherboard: DA0R63MB6F1
REV: F
Hi everyone,
I've a problem with this motherboard. At first, I have replaced the diode on the input of board because was shorted and now it's possible to have 19.5v. I've checked the entire rail of 19.5v and is it ok, checked the 3.3v on the bios chip and it's present as well as on the SIO chip and on the power on button. When I press that button, the voltage goes from 3.3v to 0 but the motherboard won't start. ACDET pin on PU5 BQ738 is 2.7v.The laptop doesn't have the battery.
Can it be a bios...Last edited by Bad_IC; 08-05-2021, 02:19 PM.
