Hello to everyone in this wonderful forum.
I have this SONY LCD TV KDL_46R473a
PSU GL5 APS350 :1-888-122- 12
MAINBOARD FY13_EU IP-012C101-4010
black screen ,no STB no life almost death.
on PS all the required volts are present 394V on the main cap and those on cold side 12.41V,3.45 and 3.45 are on
Also 3,5,and 12v are on.
nothing happens if i disconnect the PSU from the mainboard as on Samsung because here i think the mainboard gives the signal to the ps.
don't know what to do next all suggestions and advice are very welcome...

Hello all.
Not very familiar with transformers and did not find the datasheet for this one.
Would these resistance values from Pimary and secondary normal? (check photo in red)
Maybe someone with more experience can help me here

Hi there, I'm hoping for some help. I did a bios update a while back, and have had problems since - laptop taking 30-60 seconds to post during boot, unable to correctly go in and out of sleep mode, causing battery issues. I tried to redo the BIOS update but it fails each time. I googled around, and there's lots of similar symptoms on the same model as mine, where people say the ME Region is corrupted. When I boot to my BIOS, alongside ME is blank. I've tried to follow a few guides but am struggling and hoping someone can help me.

Hope someone can help me, this is the second time I have killed one of these and I wasn't able to fix the last one. This is a portable Farad capacitor-based welder: [URL]https://www.aliexpress.com/item/1005004682391629.html[/URL] it has worked very well for me, but the DC jack failed. I replaced the DC jack, but did not wait for the capacitors to discharge, and in the process accidentally shorted the green COM wire (that joins the middle of the capacitors) to the -12V terminal. After that there was a burning smell. Now the machine turns on and runs but the capacitors do not charge up.

Hey everyone!
My KORG iS50 has a volume issue where the internal speakers are only acceptable above ~50% on the master slider. What's worse is that the headphone (phones out) and line outputs are extremely quiet, even at max volume. Both left and right channels are equally affected.
Here's what I've checked:
Voltages: Vcc to DAC section measures ~5V, MUSB (mute pin on the DAC) measures ~4.xxv, and the 2 op-amps show ~9V
Master Volume Slider: Resistance ranges from single-digit Ω to ~11kΩ (seems functional).
Visual Inspection: Capacitors on the main/speaker...04-23-2025, 12:25 PM -
I picked this up and it had picture but no backlight. I was somewhat familiar with his TV as the LED driver fails a lot on this model. But when I tested the LED driver it had all the voltages necessary. I even had a spare one to try out just in case and that one did not solve the problem either.
I tested all the LEDs before pulling the screen apart but ended up pulling the screen apart anyways to further test them. Every one of them tests at 90 volts with the tester. They all light up. I replaced a couple as seen in the picture because I had extra and I accidentally popped the cap...04-23-2025, 06:15 PM

Hey guys,
so my half-year out of warranty Dell Latitiude 5320 (19817-1 SOUTH PEAK 13 10L) w/ i5-1145G7 and 16GB just started to act weirdly...
The first/upper USB-C/TB port suddenly didn't accepted the charger every time and sometimes only a different one... or with a different cable but so far, the self-diagnostics didn't noticed anything so I suspected a dirty port.
Today however... it stopped completely to accept a charger, the second/bottom one however does and after a half an hour, I notice something getting hot under there... blazing hot!
