Hi There!
I have a TV set (model TD Systems K32DLV1H) which doesn't power up.
During power off, the stby red led is on, as it should, then I press power button on remote and the led starts blinking, endlessly.
Sounds to me like a PS problem. TV is kinda alive as it stays in Stand-by, recognizes power up button from remote, etc, but can't really power up.
Internal PS is a 17IPS11. First inspection shows no damaged components, no swollen caps, and multimeter shows all diodes are good. Also there's a dual diode transistor shaped component on a heatsink that measures ok, and also a (probably) mosfet on another heatsink measuring no shorts on any pin
Being lead by other forums it makes me believe it could have to deal wih the backlight. Now the question is, how can I determine, without removing the LCD panel, if the issue is with the LED strips themselves, or the LED voltage generator in the PS? Or maybe you guys can provide any other hint on what to check?
Any help would be greatly appreciated!!
Thanks
