Re: samsung ue55ju6800 problem with brightness

I would replace the whole set of LED strips.
Once it is finished you should turn down the backlights level on all input setting to as low as possible to extend the LED's life.

by THXFX

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...

Samsung UN55JU650DF network/streaming problem

by howardc64

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...

Samsung UN55MU6103F video problem; has colored stripes on the display

by alro7779

Hello, everyone!

A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,...
