Re: Lg 50pk790
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
Ok I turn it on either by the tv button or the remote and it turns on, clicks as normal and lights up like it's going to go to the logo page But then goes black. The standby button lights up blue as if on and fades in and and out then goes black. If I turn it off it does go red to standby....Leave a comment:

Re: Lg 50pk790
Ok think someone on another site told me the wrong boards. I was told to replace main board and he showed me the little one with the square surface mounted chip. But now I'm thinking he meant the one with the hdmi ports on yes???Leave a comment:

It lights up brighter, like it's turning on then it goes dark again but the tv is still on. I then press the standby button and it clicks ok like its going off.Leave a comment:

My tv (model in thread title) has all of a sudden lost picture and sound. I'm quite compitant fixing pcb's etc as I worked in electronics but I have no testing equipment 😔😔. There are no sign signs of blown caps or resistors etc.
It was fine last night, there she been no signs of anything suspicious building up problems. It literally turned on and there's was no picture, the sound could only Be described as satanic talking (lol) for a few seconds then nothing.
I can turn the tv on and the standby light goes from red to blue, it goes bright like it's... -
