Re: Samsung UN32EH4000 with colour problem.
First, unplug one of the ribbon cables that goes from the TCon board to the LCD screen, test, then do the other ribbon cable. You end up hopefully with a half of a good screen. Anyway... clean the bad ribbon cable and also try to put a little pressure on it, maybe there is a bad pin on the ribbon / slot.
If that is the case, some folks make the ribbon cable thicker, by putting some scotch tape on the backside to increase pressure when the ribbon cable is snapped in. -
Re: Samsung UN32EH4000 with colour problem.
Oyyyy, that sucks. Only thing you can do is to clean the ribbon cable on both ends and check the tab bonds and the LCD.Last edited by CapLeaker; 02-21-2016, 04:53 PM.Comment

Hello dear friends. I have problem with a Samsung UE32EH4000W. The tv starts with good Colour quality and after a while the colour changes. Anyone can help me please -
Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.
This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable... -

Hi I need help with a Samsung un43nu7100 BN94-13191C/BN41-02635A with boot loop problem even with tcon jumper.
I've already try tape method and same happen, if I disconnect both flex from mainboard to panel tv boots normal even I hear Samsung sound.
When I solder jumper to make t-con work with or without panel or panel cables connected it still reboot or power cycling.
What I noticed is that there's no voltage in VHG, HAVDD, PANEL_3.3V, AVDD_17V or 12v near dc-dc chip.
I check capacitors and diodes and didn't find any short IN MAINBOARD.
Measured all power supply... -
Hello,
I'm experiencing an issue with my Samsung LN52A550P3FXZA. Upon powering it up, I initially see a ghosting effect in the background along with some slight red pixelation in certain areas. This then shifts to green pixelation in the black areas. The picture quality fluctuates with noise for about the first thirty minutes before it eventually clears up. I suspect the T-con board might be the culprit, but I'm also concerned that there could be a problem related to my previous repair. When I turn it on, I hear a click, and the red LED light flashes three times before the screen comes on....
