LCD tv display turns on and off immediately but sound ok

The tv is acoustic solution brand and immediately you turn it on the display just flash and goes off while the sound is ok.


Thougth that the problem is with the inverter board but I detect fault on the power supply board

 Capacitors 220uf400v and 100uf50v bad and replaced.Fault cleared

It is your leds. You get a flash on the screen when you power it on but then goes to black screen. You have a couple of leds that are not working behind the panel. I have replaced many of these on many tvs. It's a total breakdown to replace the strips of LED. Get some ideas from here TV Repair
