So I purchased my Sony XBR55X930D used for around $700 a few months ago and now I am having a really strange issue. I plan on fixing it myself if I can figure out what the correct part is. Anyway I power the TV on and it comes on, android logo comes on, TV boots and sometimes has a signal for HDMI and sometimes doesn't. After a few minutes if a signal is displayed the TV just goes all black (no backlight) and flashes a red light 7 times. I have to unplug the TV to restart and it does it every time now and the TV is not useable anymore. I love this TV, it even does it when I access the settings and it will just go black (no backlight) and flashes a red light 7 times. Now my Sony 4K BD player there is no signal anymore. I would have to point to the Mainboard or LED Driver board or power supply. Anyone with knowledge of this model please lmk what part this could point to and I'll start from there. I'd like to fix it myself since I have no warranty and it was purchased used. Thankyou for reading my post! So the problem is there is no signal with HDMI or signal dropping for HDMI and sometimes freezing, TV goes all black (no backlight) and flashes a red light 7 times and sometimes does not respond to pressing power button on either remote or TV itself.
