hp Pavilion 14 CE-1XXX
MB G7AD-2G DAG7ADMB8D0 REV D
Processor i5 8265U
AFAIK schematics or boardview are not available for this MB, but I used a similar board as a reference (G7AL-2G)
Laptop came in not booting with caps lock blinking 3 fast- 2 slow indicating RAM error. Charging works fine. Found bad soldering on the only ram socket present (2 outer left pins and 2 outer right pins).
Once soldered the laptop started fine and I was able to install Windows 11, upgrade BIOS to version F30 from Windows without a problem, BUT I found a strange and annoying...

It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.
The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help... -
Hello all,
As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere... -
Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Good morning... I'm new here and have a LOT to learn.
I'm a rescue-er. I live in NYC and I don't even want to get started on the amout of stuff that makes it onto the curb, to be crushed and in a land fill, simply because our repair shops have been sold out and because - well, it's a disposable society... Anywho
I have 1 motorcycle, 3 Jaguars and a Porsche that were all headed to the crusher due to a couple handfuls of needed parts and a Lil Love,,, I'm hooked on the rescue. A member of several forums and a huge fan of DIY environments such as this one. Hats off to you...
