Hi
Would be greatful for some help regarding this problem.
Tv turns on , Hitachi logo appears with no problems , then depending on how lucky i am i either get a fully working tv for around 5/10 seconds and then the left side of the screen dims down (not dark just dimmer than the right) or sometimes it will just go past the boot logo and go straight to the dimmed left hand side straight away.
Sometimes turning the tv off and then on again will make it fully bright again but it will then dim on the left shortly after.
It is a vestel setup with a 17ips71 (190814R4) psu board.
When the tv starts and the lights are fully working i get a low buzz from the psu board and when the lights dim down on the left the buzz goes,i'm not sure if this is relevant, the only other visable thing i can see is on the back of the psu board at Q17 is a component that has made a brown mark on the plastic backing sheet (maybe got hot?)
Any suggestions would be most welcomed
Thank you
