The diodes that you are saying are +12 and +24 volts when you remove the socket to the solid motherboardComment

Re: vestel smart 40 pf7070 led tv is not working
With the television switched off use your multimeter set to diode mode and check any of the diodes mentioned above to see if any of them are short circuit.

The 0 ohms smd is a zero ohm resistor which looks as though it is being used as a fuse.Willing to help but I'm no expert.Comment

You need to unsolder them carefully and check them for short circuit. Do not lose them.

Dear friends,
i do have a VESTEL 17MB82S not working. Here is the story:
First, when i give power on tv, red led lights after some blinkings and i've noticed that picture apears but no backligt at all (i use a small light to see it).
Then i do flash with a FAT32 USB stick, the upgrade_loader.pkg file with the known OK button method. After that, the TV stops and when i press the ON-OFF button from remote control, the red led goes on but no backlight no picture at all.

Laptop is HP Envy x360 13-bf0013dx, hp website link, it's an i7-1250U with 8 gig onboard ram.

Originally you'd plug power supply into it and it would take up to 1.2 amps and then drop to 200 milliamps and then go back up again to 1.2, staying all the while at 5 volts. Pressing power button would results in power LED blinking amber 3 times. 3.3 volt rail, 5.1 volt rail present, main power rail 8.8 volts. Power button test pads near EC chip 2.7 volts.

Apologies if this is the wrong forum, but I'm not looking for a specific BIOS file, I'm trying to understand how one makes a clean BIOS file. So here's the background. I have 2 HP EliteDesk 800 g2 mini 35w pcs. One is working fine; the other doesn't have display out or working USB's nor does it have any flashing error lights. The CPU does get worm enough to cause the fan to spin up, so I think it's posting, but I just don't know.
