            Yeah, I swapped out the mainboard. Was very hard to find one and when I did, it was almost 300 bucks. Found one for $100 on ebay!

                Hey guys. I sen this main board to PTS to have it repair and tv is now working. Found that parts they replaced on it are: IC203 and IC503. The description on IC503 is IDT6V100-12PGG. Do you guys know what this IC does? I been looking for specs but can't really find much info.

                Thanks and Hope soon we can get the fix for this board as this is becoming almost impossible to find a replacement.

                    Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
                    by Nairolf
                    Hello,

                    I have a Samsung DM32D display.
                    When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

                    Here’s what I have tried so far:
                    1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
                    2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
                    3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

                    From these tests, I suspect the problem might be on the mainboard. Could anyone...

                    Samsung Series 9 - BIOS issue
                    by Kjell
                    After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).

                    Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...

                    Samsung HG49EE690 Hospitality TV reboot issue Mainboard BN94-11086A
                    by alltvrepairs
                    Hi,

                    I have 3 of these TVs for repair with same problem of going to standby after around 10minutes and start again continuously. I have tried a new SPI 25Q40 but fault remains. Am suspecting a CPU problem as it gets a bit hotter than I expect.
                    This seems to be a common problem in these models. I am 100% sure it is a mainboard issue as I have fitted a spare from a normal TV from a UE40K5607 and stays on (diplay inverted but I managed to rotate in SM using a different display).


                    Any help appreciated!...

                    Samsung SyncMaster 740n Phase Control Issue
                    by vincentedel
                    Hello,
                    I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

                    I'm using the Samsung 740n monitor drivers instead of the default plug-and-play...
