Hello,
Here I have the mentioned tablet with motherboard s6000-mb-h401. The tablet won't turn on, no display, charging normally. I manage to connect to UART port and got this output when I try to start it:
...Code:[PWRAP] pwrap_init_preloader [PWRAP] pwrap_init [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=0 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=1 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=2 rdata=5AA5 [PWRAP] _pwrap_init_sidly [Read Test] pass,SIDLY=3 rdata=5AA5 [PMIC_WRAP]wrap_init pass,the return

I bought 6 second hands odd $5 at a flea market and I found that 2 odd(GCC-4521B,TS-H192) won't read any disk.
But I measured all ESR value of SMD capacitor which is located on the TS-H192's PCB and replaced two capacitor which has higher ESR value.
And To My joy,this TS-H192 odd finally recognized burned CD as well as pressed CD.😂
But there was no more good fortune for GCC-4521B..In order to dead GCC-4521B back to life, I replaced three capacitor which has higher ESR value and I rubbed silicon grease on the every glides.I even brushed lens with cotton swab which was soaked...02-13-2024, 07:31 AM -
a friend of mine brought me a Karaoke Machine that was somehow damaged in shipping and will no longer read the Burned DVD that was in it when it was shipped. they swear up and down that it used to read that DVD just fine. The drive was making all kinds of horrible noises and wouldn't read any discs when i started working on it. after cleaning the lens and adjusting the spindle it will read regular CDS now but still wont read any burned CDS or DVDS or even regular DVDs. is this the proper place to ask about this?
cause its a video karaoke machine... not strictly "audio equipment"... -
Hi.
I have a laptop Dell Vostro 3501 which did not POST. When connected to power supply and turn it on, the keyboard backlight would turn on but nothing else. Sometimes there was 1 BEEP code indicating problems with BIOS.
Then I disassembled it to read the BIOS chips. It had 2 - 64mbit and 128mbit. I connected CH341A (with 3.3v mod) to both of the chips (still soldered on main board) and read them.
After I reassembled laptop back and tried to turn it on. Now there is no sign of life. Not even keyboard backlight.
Then I took the motherboard out... -
Hello Everyone,
I will be really grateful if someone shares schematics and if possible the boardview of the old Asus Nexus 7 (2012) Tablet. The motherboard is ME370T Rev. 2.4. Now I can find schematics for the Rev. 1.0 but I could not find the schematics for the Rev 2.4. I tried to look for similarities in the Rev. 1 but there are somethings missing, plus the board i have has nearly no component names printed on it which as a newbie makes pretty hard for me to locate things. Any assistance will be appreciated. Thank you.
