(TLDR: It was capacitor C6519 [Koshin KZH 50V22uF] and C6515 [Koshin KZH 25V47uF] on the power supply. I have questions at the end)

Always use caution when working around mains power and high voltage capacitors!
Hey guys, I'm repairing a Denon AVR X6400h for my brother. It quit powering on after a power outage. It acted like this last time there was an outage, but after letting it sit overnight it started working again for a few years. This time letting it sit did not bring it back.
SYMPTOMS:
-No display...

So I got this Sony and purchased it working.. got it home and it was 4 blinks red. Seller actually refunded me thankfully. Now it's massive to take apart and I know 4 blink can be the panel sometimes but not always..

But I found a method through other ways with grounding out the bl error pin on the LD driver board. Now the tv turns on and works.

Pin is number 27. It was either remove the resistor right next to the solder pad or solder the pad to ground. I soldered the pad.

Now what is this going to do to the tv? Is it just going to die shortly down the road?...

Dear friends,
I’m currently looking for the schematics of the ASRock C3558D4I‑4L motherboard. If anyone has a copy or knows where I can find it, I would really appreciate it if you could share it with me.

Thanks in advance for your help!...

Hello Guys

I'm currently fixing two different Dell latitudes,
I need a E5550 BIOS - SERVICE TAG is: FSFB262

So far I flashed about 6 BIOS from this forum already,
none worked,
only fan spin ~3s, LCD black, keyboard LED on/off ok,
I tried manual extraction with scripts for ages so to speak. VM is untried yet.
This laptop is not burnt, it seems to just have a corrupted BIOS.
I extra baught ram. This has to work friends.

Do you generate it this way in Windows in CMD?:

E5550A24.exe /writeromfile C:\bios.fd

Hi, I have a MacBook that won't start at all, no sign of life, no display but the trackpad reacts., it's the A1932 820-01521-02 model with T2 chip, I tried to flash it in dfu mode it's detected on my mac, but it gives error 9 when I want to restart the chip, and error 4010 and 75 when I want to restore it, yet the icloud was removed on the icloud site the mac was deleted, anyway it was a little oxidized slightly so I cleaned everything, now I took all the voltages here they are:

pp3V3_UPC_XB_LDO : 3V27
PPVBAT_G3H_FUSE : 12V6 UNSTABLE FALLS to 0V187 every 4 seconds
