Hi, this is my first post!
I have a Techwood 40AO2USB TV which when turned on flashes a blue led and then steadies this. I assume this is a Standby Mode. I can not make the TV do anything else (other than switch off - blue light flashes again and then goes off). I assume the TV goes through it's checks, then finds something that is not right and goes into Standby. Can someone please suggest what I should check/test to narrow down whether it is the PSU Board (markings: Vestel 17IPS20, 23250360) or the Main Board (markings 10099021) or the Backlight Assembly, OR something else. I have a Fluke Meter and I am competent in using it, and I am electrically-aware on safety. I am not after component identification & replacement, rather to know what replacement board to change without spending money unnecessarily. I can provide photos if helpful.
Thank you!
