Re: samsung flat tv has no picture
Try a "hard restart", which simply means unplugging the power cord of the TV , and replugging it 4 hours later. This technique is useful for reprogramming the electronics of the TV. Hope it works for you.

This is caused due to random falure of vertical scan circuits. It generally is caused by dried out capacitors or bad driver IC. Unfortunately it will get worse. If you fail to turn the TV off quickly you will burn a permenant horizontal line on the tube. Trip to the repair shop I am afraid.
If the main PCB is not cracked too bad, it should not be expensive to repair. You have lost vertical deflection causing the flat line.There may be a crack at the flyback, where the vertical IC gets its operating voltage, or a crack at the pins of the vertical IC itself.
keep tv off.
it will only get wors
if sumon dosent work on it soon
the problem you are having in the vertical section of the tv
hav a repairman resolider all conection on the vertical IC and check the serounding componets for falts.
PS the repair takes me about 15 min.
Hi, According to the symptoms, There is a problem in vertical out section.Just check it there must be a capacitor that has been burst or leak.And second one reason could be the malfunctioning of vertical IC.Which is also in the vertical section.
MOST BE A VERTICAL PROBLEM if the line cross the screen from left to rigth,,, and if the line cross the screen from top to buttom then is an horizontal circuit problem any way you need a tech how ever if you know about tv repair and have somes skill in the campus try resoldering the vertical output IC....good luck and rate me
have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?"
I would love to save the TV.
nothing to worry just minimise brightness to avoid screen burn.
means one bright hor.line in the middle of screen.
this problem can be solved
1 check vertical yoke connector or wire loose
2 check supply to vertical section which normally comes from EHT transformer
check components in vertical section or print loose
