Evening all, would any of you kind people know what the cause would be for my samsung 40 " tv to have sound but no picture? There's nothing there, the screen is just black. It was working quite happily yesterday but i've just got in and switched it on and this has happened.
 
Very good point bud, I have experienced the same problem too, and it was a scart not pushed in properly, but I would expect the OP writer to have checked that??? surely haha
Assume nothing where i'm concerned :D i once broke down on the motorway so i rang my old man to come out with a tow rope and loads of tools when all i needed was a gallon of diesel :D i'm not the most observant of people but this time yes the scart and other leads are fine, i think the problem lies deeper :(
 
Sounds like a power supply fault, and would agree caps are the usual caurse....suggest from the power input follow circuit back any see if any of the caps have there tops distorted or basically swollon,
 
only ever bought one samsung TV... had it a week before returning it !

kept turning itself on during the night scaring the living daylights out of you, plus the volume was crap !

only ever bought LG since then, never had an issue with LG stuff either. always been good !
 
Too hard for me, my probe tips are about 5x bigger than the components.
Zapped myself on the input caps on an Apple power supply earlier that I've been given to fix!
Discharge the buggers next time.

post me it and I will fix it.....or I can advise from a photo of the circuit board and a short description of the issue...
 
Ok seems to be a common fault, no back light and picture but sometimes sound. which is supposed to be invertor psu, Now i`m no expert on tvs, but have used this company before to buy repair kits for sky etc, with no problems, but your gonna have to be good at soldering, because these are small components.
