Hello guys, I went to reball this one (yes it has been reworked by someone who was not careful with removing of the black epoxy).
So here is the picture is this a dummy pad or not?
The pad is destroyed not fixed. Since he destroyed the mask whole dummy pad (yea its dummy) is lifted and it looks like its fixed .
Today everyone tries to do reworks ^^.
Hi friends, I have a Lenovo E14 Gen 2 Type 20TA laptop with serial number MJ-0GWZSZ TYPE 20TA-002CUS. Intel Core ™ i5-1135G7. It has Winbond 25R256JVEQ BIOS which has black epoxy resin. I have 2 questions. What method do you use to remove the epoxy? and the second, what chip do you use to program it if you have the TL866 II Plus programmer? Thanks in advance.
Hi, I got this Fujitsu Siemens Amilo Xa 3530 Model: MS2244. from a friend and it is powering On, but only functional keys lights up, fan spins and nothing else, screen is black no backlight, and it's staying like that forever. I tried other memory that I know is working, I tried to empty capacitors by holding power button without battery but still nothing. I didn't try new cmos battery, need to disassemble it first to try that. But I don't think even if cmos battery is dead it would give some backlight and picture...I kind of think it's chipset or gpu dead.
I read something on google that...
Following a short circuit on the controller board of my heat pump, I'm looking to replace the components shown in the photos. All I know is that they are diodes (but I'm not sure what type), and I haven't been able to find their equivalents.
The one on the left says: 15A 5BA
The one on the right says: DTZ S47 or DTZ 547
Does anyone know how to identify them?
Foremost, I am not an ecu specialist. This ECU: Siemens S11868502 D SIM24 (Ford KA 1.3 Petrol) ended on my bench. It was previously worked on by an unknown technician. The only information I have at hand, is that the owner replaced the ignition coil as the latter caused one of the IGBT's in the ECU to short. The IGBT I can source and replace, but it seems that the previous technician removed 2 components (most probably resistors in a mini-melf package): see attached photo. It seems that schematics and/or board view files does not exist. If there are any ECU specialists that can assist in identifying...
