Chosen Solution
I have a Philips 55” Smart tv Model:55PFL5402/F7. The picture started flickering one day while I was watching tv and the picture hasn’t come back on since then. The backlights are all lighting up and the tv is definitely coming on and the sound is still working. What is causing this? What part of the tv needs replaced??
Because you mentioned flickering, my first suspect is the T-Con board. Make sure the number on the replacement T-Con board you get(e.g. 6870C-0584A) is exactly the same as the number labeled PN on your current board(you can find the number by the LG logo).
@victoriaashley you got two candidates left. One is the main board because of the flickering snd still having audio, the other one is the actual panel. You could check the connections from the t-con board to the LCD driver board and see what the voltages are. We would need to get the info of the driver board to see if there is a datasheet so we would know if it works etc. That is worst case scenario.
Hi @victoriaashley , Here’s an image of the no picture troubleshooting flow chart #10 from the service manual that may help to find the problem.
