I've had this [URL="https://www.panasonic.com/global/energy/products/eneloop/en/lineup/charger-bq-cc63.html"]Eneloop charger [/URL]from new, and it works fine but has always made a really irritating ticking sound roughly once per second when more than one battery was inserted. I found the noise to be coming from the OB5222AG PWM DIP-8 IC. I tried replacing it with an identical part - the problem persists but rather than a ticking, it now sounds like a squeal. The problem is there are no spec sheets for this IC [I]anywhere[/I] and no information besides it being a PWM IC, so I have no...Yesterday, 10:08 AM

Samsung UE55JU6800K with no image on screen.
I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.
Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.

Hi Folks
I got an ASUS ROG MAXIMUS Z690 HERO mainboard with missing components on the backside near the HDMI output.
Unfortunately there is no documentation available nowhere for that board, I did also not find any similar ASUS board design. Even Russians nor Chines have anything available here (nor BV, nor schematics), so only way to discover the parts is from a real physical board.
On the picture left the area where the missing componets are is shown.
On the right picture the detaileed view is shown.
It seems that a double mosfet is missing, probably...04-26-2024, 04:46 PM -
Hello,
im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...
Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...04-24-2024, 09:01 AM -

Hi I have a touch screen monitor. It work fine for many years, but now It shows its age!
When I turn on the monitor, white lines appear on the display. They jump for a few seconds and then the display goes off.
Can you give me some pointers on where to start with the diagnostics.
There was a trail of dried light brown liquid on the board that the display connects to, as if a capacitor had leaked, but I couldn't find one. I cleaned the circuit board and resoldered the legs where this liquid was, but to no avail....Yesterday, 03:52 PM -

my laptop has a weird power-on issue.
Once the laptop has been powered on, it can restart/ wake just fine on battery power or Adapter, ONLY If i have not closed the LCD.
If i am running on battery and have closed the LCD (even momentarily). it will not power-on/ wake-up on battery power no matter the battery percentage.
but once i open the LCD and connect it to the adapter (even momentarily) it will wake up gain and I wont experience any issues till i close the LCD.
i do not know where to look for repair.
thank you all for any advice.04-30-2024, 04:36 PM

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...Yesterday, 03:25 AM -

Good morning
I am encountering a problem on an Asus X421EA card which no longer starts; I checked the voltages, the 5v and 3vd are missing, has anyone encountered this problem, I have been looking for several hours without finding the source of the problem. Thank you!Yesterday, 02:27 AM -
Hi there,
I have a Mac on the bench that wouldn't turn on, it didn't have PPBUS_G3H voltage.
I replaced the IC U7000, ISL6259 and the green light came on, the cooler turned on and showed the video, but I noticed that PPBUS_G3H is at 9.45V and the U7000 is heating up a lot.
I took resistance measurements for the earth and did not find a short circuit.
I measured the resistors connected to the U7000 and found no different value.
I searched the Forum and didn't find anything like this.
Can anyone give me any advice about this problem?
Thanks in advance.Yesterday, 02:00 PM -

Hi all,
I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.
After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.
I hope someone can help me out. Attached is my [B]ORIGINAL...05-02-2024, 12:18 PM -
