Samsung TV no display but has sound

[Rodville]

I can not find a model number on the back panel but inside there is the model s50hw-xb03 on a sticker on the screen.

I got this free because I was told there is a "bad fuse or something" and it should be an "easy fix". That said I have tested the fuses on the board and none are bad. When first plugged in there is a blue light by the power button. The light flashes with any remote signal. I plugged in a DVD player and got nothing. I happened to press the power button and the blue light went off and there was audio from the DVD but only in the right channel. The volume works and the source button stop the audio until I press COMP on the remote. I have the DVD plugged into the composite connector. With the blue light off there are two green LEDs on the one board that are lit up. I can not find anything on the model number s50hw-xb03 but a link back to this forum. So I am not sure if this is the TV model number or what. I was told it was a 55" TV but I don't think it is with the 50 in the model number.

I took a pic of the back and a vid if what happens when on.

Owners saying a fix is easy fix is never an easy fix lets get that clear for a start lol. In a dark room with the Tv on does the screen appear to glow like a lit up grey ?

I will be able to check that later it's currently in a room that has a sliding glass door and I can't move it alone.

Do you have all the voltages given, as written on the label attached to the panel?

Common issue with these is the Ymain 8 small Zener didoes tend to blow causing no picture. Start off by checking the Vs voltage from the Psu. Then the voltage on both sides of the fuses on the Sus boards.
