The first place to start is with the Main bd. The second cause would be the T-con bd. Have a trained Samsung tech troubleshoot to find out and repair the set.
If its Dead Dead ,that mean no power is getting past the fuse :> then it needs a fuse
.30 vs 300.00-400.00
Ok there is a way of telling if its posibley
just a fuse . First no blinking lights ,good
no clicking sound from the set when you
try to turn it on .good
now unplug the set for about 30min
the plug it back in slowley if you
see and or hear sparks coming from
the plug , this is normal but bad news
for it being just a fuse , if you dont
see or hear a spark its likley just a
5-8 amp fuse blew inside the set. :>
check to see if a flower appears on the screen. If it does then the camera is set to macro and all your pictures except close up will be fuzzy. To switch macro off, move the ring on the front of the camera till the arrow is pointed straight down. I was having the same problem. Wasted a whole day of vacation pictures. That was what fixed my problem and I hope it fixes yours too,
hello .this does sound like bad solder joints .all printed circuit boards do this after a while due to heating and cooling .is not advisable to try to repair yourself .possible electric shock and spiking .will do a lot of damage .take to a shop to have repaired
Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears
.if your tv is very old than it might be due to crt getting weak
crt base loose
loose contact in power supply
thanks
Set has sound, but picture takes 30min. to appear
Very helpful
