Looking to up my game a little bit, but these programmers seem a bit daunting.
Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.
Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.
My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.
I may do eeprom as well. Can someone point...

Hey. I've read plenty of discussion on AVforums, reddit, LTT, and etc.
Has anyone succeeded with VRR? Anyone managed to use a different TCON board for possible VRR?
My B7 has 16K hours and basically no burnin still, very slight on yellow, unnoticable in regular use.
The bummer with it that it's HDMI 2.0b, so can't even fully utilize the panel, at it looks pretty much identical to the C3 that I've recently fixed by replacing liquid damaged components (Besides T-Con board, as the replacement one gave me vertical banding.

Hello,
I have this Thinkpad T15p Gen 3 laptop. It starts normally with keyboard lighting up, I can hear the fan starts spinning, amps quickly reach about 1.7A without the battery, CPU gets hot. However, it is not posting.
I suspect the BIOS is corrupted. I am providing 2 BIOS files as I see 2 BIOS 256Mb chips. I am also providing a photo of the chips' location on the motherboard.
Model: Thinkpad T15p Gen 3
S/N: PF-45G6VM
Type: 21DA-000PUS
Motherboard: NM-E221
Thank you....04-24-2024, 10:40 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 -
I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...04-18-2024, 03:50 PM

I have a ThinkPad T460p that keeps restarting instead of shutting down. The culprit is the LAN: if it is disabled in the BIOS, the problem is solved. I have already replaced the LAN chip (WGI219LM) twice, done CleanME, flashed another BIOS. Unfortunately all without success. What else can I check?Today, 12:26 PM

Hi, I have bought a non working PS4 pro. The seller said that the PS4 was working, he changed thermal paste and now BLOD for 5-10sec.
While inspecting the board (NVA-001) I found this component that was damaged (see photos).
I was wondering if someone knows what component it is…
Thanks

Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

Hi
I try to repair a asus Asus X571GT (DA0XKTMB8C0) no power no lights.
I saw a burned (small hole in it) chip (JW10F) proberly a TPS22976DPUR, I removed it, now with power connected the laptop turns on and direct off again, power led and fn will light up.

Result is still the same, turns on and direct off again, first attempt is with backlight on all other direct attempts are only the power and fn led.
Could it be the chip is to diffrent to make the laptop work again ?

Having this very weird issue.
The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.
I swapped with a working screen from an A2141 waiting for parts.
The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.
The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...Yesterday, 01:37 PM
