by Willem01Hi all,
Error – TV not powering on - with standby red –led flashing
Model- LEDTV – 39T3500
Power boarD - shg3206a-101h
I have read through the Basic LCD TV and Monitor troubleshooting guides.
https://www.badcaps.net/forum/showthr...956#post305956, I am no ELEC engineer but can use a multi meter and soldering iron
In the meantime I could not see any damage to any caps on the cold side of the power board, so I have replaced all of them.
Unplugged the power connector on the board, I plugged the power cable in waited... -
by STKR123As 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,... -
by rabbitukI have got a Sony HCD-BX7700dbi that isn't worth a lot but I'm keen to learn how to repair and would appreciate some help with my train of thought. The protection circuit is kicking in and the standby light is blinking. It goes into protection mode within a second of powering it on.
So far the relay on the power board that enables the main transformer clicks on and then off when powering on the unit. Looking at the schematics, the permanently enabled power rail called 'unreg sub' provides about 13.5VDC. Where the power comes into the main board on connector CN303, there is a diode...-

by BloopetaHave a Samsung UE43KU6400U that will not turn on, just continuous flashing red standby light.
Power button does nothing
Have unplugged the mainboard, and backlights illuminate.
Have tried removing panel ribbon cables one at a time, and that makes no change.
With mainboard unplugged, all voltages from powerboard seem ok, but with mainboard connected, they never quite reach full voltage, and drop and raise in a constant loop (in time with click noise from mainboard.
Using backlight tester, I get 63.6v on both sides, so seems like no bulbs... -
by 7onyThe TV is a 2013 Samsung plasma, model # PN60F5300AFXZA.
Snagged it up in non-working condition a couple years ago. Previous owner said that sometimes he could get it to come on after repeated tries but other than that he couldn't get it to turn on.
Personally I haven't been able to get it to turn on at all. The standby light comes on solid when plugged in, but pressing the power button results in the standby light flashing once every 4 or so seconds. No "click" noises, no light from the panel at all. Just the flashing standby light.
