Logik tv lcx27wn2 sound but no picture

The backlight led is burnt out, time to replace with new one. Most of the time it’s only 1-2 led are burnt. You need an electronic technician though. I may guide you if you want further assistance.

hi could be bad capacitors in the psu board,thanks

It is not with the problem to any capacitors. It is the problem with its main board itself. There should be shorted component/s at it. The short circuit protection function activates, and that why you're seeing a flash on the screen. Contact any service technician to troubleshoot. This is not a user repairable fault.

I have a UA40EH5000M samsung led tv. Suddenly the screen went blank. only sound is there, no display. Which part may have the problem..please suggest..

your cable is split into two different connections for your tv... the red green and blue cables are for HD only. They are their own little set. the yellow cable is your video cable for normal tv's. the red and white cables are sound cables, also for normal tv's. I would unplug the red, green, and blue cables, and use the yellow, red (right sound), and white (left sound).

Good luck!

Power supply board is dead,replaced the power supply board will get power.

found user manual

Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.

WHEN I TURN ON MY TV THE LED IS RED THEN GREEN AND GOES BACK TO RED AND NO IMAGE. WHAT COULD IT BE, i ALSO DID A HARD RESET BY REMOVING THE WIRES AS THE TECH HAD SAID AND NOTHING.
