Good afternoon! I have this TV with a Chinese combo plate. The symptom is that you turn it on and the standby LED goes on for a while, alternating red and green. In the end it remains green, but without image and without backlighting. I have measured voltages and they are fine, even the TCON has its correct reference voltages. I think it must be a firmware problem. What do you think?

Hi !
I got laptop that won't show image on screen, but looks it working.
Have all powers.Bootable usb flash memory is blinking and looks booting. Capslock is responding.Fans is spinnig.
But no image on screen and green led is always blinking.
Seems to me this is "Modern Stanby" mode advertised on Razors website and laptop is stuck in this mode.
I did remove battery and CMOS. no luck.
I reflash bios from Razors page but still no changes, still blinking and no image.
Is there any else I could check, any ideas?

There is no backlight flash, nor image on screen. No audio with HDMI source plugged in, nor does my laptop detect another monitor plugged in. T-con board makes a clicking sound with or without LVDS cables hookup or off.
My first thought was that it had a faulty PSU. Reading voltages, I was getting a swinging voltages from the DC output from the... -
