            Samsung QE55Q60TAUXXU - flashing backlight and flashing standy light--no image
            by learnmore
            Hello Community!

            CASE DETAILS

            Promblem Signs: Backlight on 1 sec off 7sec > repeat && Red standby light: 1blink, off 3 sec, 2 blinks, off 5 secs, 2 blinks, off 3 sec, restart cycle

            13V present on powerboard output. Backlight continues flashing after removing cables to pannel one at a time and even with both disconnected. NOTE: backlight STOPs flashing and remains on when connector between powerboard and mainboard (note Tcon built in) is disconnected.

            Tried inserting firmware on USB and left it in for a few hours, but no change

            Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
            by HTR-Informatique
            Hello,

            YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

            I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

            On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

            I also changed the screen because the PC fell and the screen was broken.

            I changed the battery with a new and original battery.

            I also had corrosion/oxidation on the...

            UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
            by triplefour
            this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
            i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
            unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
            according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

            Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
            by STKR123
            As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
            I wonder if re-flashing the BIOS might be of any use here.

            As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

            There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

            Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
            by DanPoka
            I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
            Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
            This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...
