Re: 42lg5000
hi thanks for reply, they are fixed patches and dont move, and they are there no matter the screen shade or colour, yes you can see the patches over the osd.
when you say main board, do you mean the lcd panel ?

Re: 42lg5000
as you look at the pic..... the spark / pop came from the right hand yellow block (bottom right of pic) each time i replaced fuse in plug. but the fuse in the psu (not present in pic) top right, did not blow even though when i first opened up tv it was blown. sorry if sounds confusing ??Leave a comment:

Re: 42lg5000

Re: 42lg5000
yes i do have a multimeter. i did this twice and then thought i had better ask about it. if you can give me a list of checks and instructions, i can strip tv down again to perform checks.Leave a comment:

Re: 42lg5000
hi, i dont know much to be honest, i have repaired 3 of these tvs by replacing blown caps. but this one, the small fuse on psu next to power input was blown, so i fitted new fuse, as i put the mains cord in, i got the spark from what i think is one of the transformers ?? and it blown fuse in the mains plug, but it did not blow fuse on psu, thanks.Leave a comment:
