Re: samsung syncmaster 715v
Please update your profile with country and mains voltage.
We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back (in the same orientation) and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.
Please do not post inline and offsite as they slow down the loading of pages.
Examples of what is needed

Re: samsung syncmaster 715v

Re: samsung syncmaster 715v
You can just Edit your post within 1hr of creating - but dont change anything substantial in case someone has read it - they wont go back and see the correction.

Hi folks,
I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:
Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about... -
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... -
Hello,
I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.
I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere.... -

5) "A13V" terminals have 12.9v
6) Stand-by test jumper on Power Supply has 12.9V
7) Optical audio jack on Main Board illuminates
8) With stand-by...
