Samsung GQ65Q60 QLED

[marillo]

Dear all,

I m new to this forum. I tried to sell my broken TV, which reboots constantly. And a guy told me that i could fix it somehow by taping some ports. I have no clue sadly how to do it and I am hoping someone can help me.
My TV has the issue, when I turn it on it just keeps going off and on. I dont see any Samsung logo.I just see the LED backlights on and off. When I disconnect the ribbon cable, which connects the mainboard to the TV panel. The LED backlights stay on.
Is there someone who can help with this particular TV. I can post pictures, and videos later?

Thanks in advance!

let start to agree on correct name of parts to avoid any mistake... the cable you disconnected between the Main Boards and the panel module called LVDS. yours LED BL come on it mean there are issue on the panel..

take out the speaker and if there metal plate cover the panel buffer boards take it out too... you will be able to see U ribbon cable ( flat cable connect 2 half of panel side together one on the the left side and one on the right side.... LVDS keep them connected.... and just disconnect one of these U ribbon one a time on the right side and turn on... take look on the screen if it display some things.... do the same test on the other side..

you can upload photos of the buffer boards over here too and the screen result too.

Thanks Diah. Attached a video. This is the situation when the LVDS is connected to the main board. It just goes on and off. The other two U ribbon cables are disconnected!

and when i disconnect the LVDS cable the backlight stays on

post clear photos on the panel buffer boards the left and right... so you will have 4 pieces

here are the pics. ihope thats what you mean? the lvds cable is currently disconnected. and also the two, U ribbon cables as well. with this configuration the led backlight stays on.

but once i connect the lvds cable from panel to main boardit goes on and off, despite the u ribbon cables disconnected

post very clear close and focused photo on this area

[marillo]

thats the left side

the middle panel board

right panel board

Man, not all,,, just one are now important this part... still i cant read the label of the parts, focus it with light. ( ich brauche nur diese Teile um Ihre Label zulassen )

[marillo]

ah here we go... sorry i thought you need all

[marillo]

here a better quality one

[Diah]

okay, now you disconnect the LVDS , and keep the U ribbon at this time all disconnected
first test with yours DM in Diode mode the MOSFET Q001, between the middle and A G
with OHM test C 621
with diode mode test D007 D008 ( between the three 123 against 456 and in reserve way

Install the jumper first, then experiment with U-loops.

i will upload some videos tomorrow... i measured everything today and recorded it. i hope i did it correctly, just dont laugh at me please... also i dont know how to interpret the readings... so i hope you csn help me with these results

i hope you can read something from these videos...

lift the 2 LEGS carefully from the board , put all cable back in place and turn on see if there are no boot loop, if no more reboot test in diode mode the Q again and compare to yours first reading

you mean with a soldering device to remove the two legs?
