Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

Re: Lg 50pk790

I believe you need a new power supply cause if u see a screen briefly upon turn tv on then your inverter is working

Hey. It may sound funny but try resetting your TV by turning it off,unplugging it, and holding the on/off button on the tv itself WHILE the tv is still unplugged for thirty seconds.

Picture was perfect before. I literally turned it on one morning and there was no picture and the sound was what I can only describe as satanic (lol) for a few seconds then nothing. No picture or sound. I cannot find a psu anywhere, they all seem to be out of stock. I take it LG's are rubbish lol

Re: Lg 50pk790

Is there a label on the rear screen panel giving the voltages and have you measured those voltages?

Re: Lg 50pk790

Ok changed the little main board but the problem still persists. Please help as I can do without buying a new tv just before Xmas.

Are we talking psu board fault?

Did you do what hamie said on the test patterns ?
because i noticed on your posts he advised you how to test but you replied you tried another main board ?
