Sounds like a bad panel. Did you do a short check for the driver ics on the flat flex?

SOURCE: Have Samsung led replaced Tcon board now have dark screen and vert-horizontal lines no picture but have sound

Check both ends of the ribbon cables for proper seating. Also make sure you didn't cross them up. You will melt a trace if you did.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board

Have Vizio E60-c3 LED TV. Picture not working, Backlights on, Audio works. Ordered Complete repair kit from Shop Jimmy.


About 99% of the boards from shipjimmy are good, unfortunately lI think you have a bad panel and its destroying the tcon board, did you check the fuse on the tcon board?

Can you help me troubleshoot my TV? It has audio but no picture.


Use a voltmeter to confirm all the voltages are present when the TV is powered on. If they are all correct then replace the led driver.

The backlights aren't working on my Samsung UN32ES6500FXZA TV. I performed the flashlight test and can see a picture and the audio works. Can you please let me know what part needs to be replaced?


You have at least one shorted LED in the panel, reason it works with the main disconnected is your removing shutdown circuitry, don't run it this way for any longer than necessary when looking for the faulty lamps..Also be really gentle with the panel and flat cables going to the TCON board, they can be damaged quite easily and if that happens the set is junk..good luck!!

My samsung led tv, when i turn on red light blinks 6 times. no display, no sound. Tried replacing power board, main board and tcon board, all of them seems to be fine. What else could be the problem.


You have at least one bad LED in the panel and its shutting down the power supply...for future reference a bad Tcon will not cause loss of sound only affects picture

Samsung SUHD UN65JS9500FXZA. The screen is black but also you can barely see a picture of you're up close. With the screen black there is good sound. Is this a tcon board issue?

I replaced the t con board and the main board in my Samsung led tv and I still do not have a picture


Hi Tony,
If the backlight is there and still there is no picture, what is left is the main board. But before that please see that the Tcon board is receiving necessary voltage from the main board. Please also check the power supply board for producing all the necessary voltages.
Good Luck.
