Samsung LA32R81BD over saturation of white
I picked this one of the curb thinking it would be an easy fix. No such luck at the moment and as my days off have disappeared I thought I'd post here for suggestions on what to try next time I retreat to the shed.
It is powering on fine and the SMPS BN4400155A appears to be working fine.
It manages to power up tune in and do everyting else just fine it just looks like some one cranked the back light up to eleven. That said there is slight discoloration across the panel

but mostly just over dosing on the back light.... -
Re: Samsung LA40A550P1FXXY Backlight Working but no Picture
Wow talk about a long time between drinks. I ordered a new Tcon and replaced it, Same result. I tested the fuse on both old and new Tcons and found them both open. I dont know if the one on the new board was good before i installed it though.
How hard is it to find and fit a replacement fuse?Leave a comment:

Samsung LA40A550P1FXXY Backlight Working but no Picture
This one was working fine after a PS capacitor fix until now, it is booting up OK but no picture on screen. Sound is good and so is the backlight. Where should I be looking next?
Oh and I know the pictures show the TCon unplugged but this is not the fault

Re: Samsung LA40F81BDX problem
OK there is four ribbon cables between the TCon and the panel. On removing them each in turn I get very similar results to the existing problem although the vertical patterns are slightly different and in one instance the half the panel is all white.Leave a comment:

Samsung LA40F81BDX problem
Ive got a curious one here. I have a LA40F81BDX it was a great TV until it has suddenly developed a screen problem. I have checked the PS for the regular problems (bad caps) but to no avail, I have also changed out the T-Con board and had no luck. It appears everything is working fine (sound, etc) and on pressing the menu button the screen does change to a different image.
I just need to know what else to try or if I am wasting my time. Thanks!
