Hello,
I own a Samsung LCD tv model le40b530p7wxxc and sometimes when I turn it on there is no image, only sound, I turn it off, wait a moment and when I turn it on again everything is OK. It will only happen when I turn it on.
I manage to check that there is image (with dark room and a flashlight) and the backlight is off.
I opened the tv, checked all caps from power supply/inverter board and they all look good, took out all boards to do a visual inpection and there is no signs of problems.
The problem is pretty random and I couldn't find any pattern, when I was ready to make sure that there is image(dark) while no backlight, I had to turn on and off several times until it happened again.
There is an attached picture of the power supply/inverter.
Any help will be welcome! Thanks in advance!
