Hi all. This is my 1st new thread. I have the above tv with the said problem. I can confirm the power supply board (mip390hw) is working properly, with all the correct voltages at it's outputs.So I guess the problem is with the main board ( t.msd306.68a). Now there is an old thread on here with a couple of members offering some help. I was hoping those members ( newtothis,steviewonder and Andrew F.Ali) are still on here and will help me please. Also obviously anyone else who can help. here is the link to the original thread, https://www.badcaps.net/forum/showthread.php?t=45888 I have put a reply at the bottom but no response. Many thanks in advance to any help.

Re: BUSH LC39GL12L - Stuck on standby light
Corrupt firmware, remove the flash Ic snd send it into ohm supplies to recover and restore it (more reliable) or replace the motherboard.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

U10 is the firmware Ic, call ohm supplies and see how much they will charge for data recovery on the Ic.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

No you need the firmware for the Tv to be written to the Ic before replacing it.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only. Anyone Doing So Will Be Banned Instantly !

Re: BUSH LC39GL12L - Stuck on standby light
Ok thanks for that Reecey. Are you certain that will be the problem? I forgot to mention, although I get all the correct voltages at psu output when pson is bridged, they do stay for about 20 seconds when main board is connected but then drop away. Just thought I'd explain this in case it sheds new light on the problem.Comment

Re: BUSH LC39GL12L - Stuck on standby light

Re: BUSH LC39GL12L - Stuck on standby light
sorry i thought i had found the link on ohms website for a pre programmed ic but it was for a diffrent model hence please ignore my post, personally ive had a good service from ohms supplies in the past if i was you give them a ring and see what they advise they may ask you for the panel number of the lcd used in your set this is usually on a white sticker on the metal tv chassis.
this is what i had found but please note the model number does not match!

Bush LC39GL12F not switching on
Hi. I have the above tv that has stopped working.When I turn it on there are no lights on, not even the red standby and obviously no screen. I have checked the power supply board and all the correct voltages are present at the output. On the main board ( t.msd306.68a 12023 ) I am getting output voltages at the terminals that lead to the LEDs, (but like I say no lights on).They read brown 5v, red 1.7v, yellow3.5v. I don't have voltages however at the terminals which lead to the cluster to the standby, volume, channel etc buttons.Any help will be much appreciated.
Just in case any one has noticed I did put a very similar post on here before, but that was after I put a 2nd hand main board in which was also faulty.With that one the voltages of the power board were dropping off after 20 seconds.when I connect the main board THIS NEW POST IS WITH THE ORIGINAL BOARD IN, WITH THE ORIGINAL PROBLEM AND THE VOLTAGES STAY STEADY. hope this hasn't confused anyone.Comment

I think you posted in the wrong section, this is the "Announcements & Related News". try posting in "Troubleshooting TVs and Video Sources"Last edited by R_J; 09-20-2016, 11:14 AM.Comment

Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power... -
The problem with my TV is very similar to an earlier post but there was no final solution posted.
When the TV is first turned on from cold it will not turn on. The red standby light begins pulsing and a high pitch whine is heard. The back light remains off. If the TV is left trying to boot like this and then turned off and on again a few times then eventually it will turn on and sit there working all day long.
I initially suspected the PSU after spotting this kit for sale,

TV: Samsung QLED QE65Q7FNAT
PSU: BN4400940A
MB: BN94-12832K
I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r... -
picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board...12-01-2023, 09:55 PM -
Hey Everyone,
So I've got this Samsung and the reported issue is that when powered on the backlight comes on, but no picture, no sound, it will flicker, the standby light will flash red twice and repeat the whole process...each loop lasts about 15 seconds.
I've googled the issue and understand it is likely a panel/driver board issue, but was hoping the "tape method" could be successful. Before I did that though, I disconnected the left LVDS cable and powered the TV on. This time I got sound, no picture and the two blink standby light stopped. Did the same...03-27-2023, 07:01 PM
