That does not sound good.

Can you see part of the image or only vertical lines?

I have a sanyo DS35580 and there is a blue line across the middle of the screen


You haven't stated whether there is screen or picture. If you see only a blue line across the screen with high brightness, vertical output Ic of your TV has burned out. Don't switch on the set further or increase its brightness, till the fault is retified. Otherwise there will a phosphur burn occur where the blue line is now, and it is internal, whcih cannot be retified anymore.

SanyoTV-blk screen w/thin line of light across screen great sound


Your Vertical Amp is probably Blown (bad) , but before you change that check all capacitors around the vertical amp IC and / or resolder resistors and diodes around vertical amplifier.
And NO it is NOT the Picture Tube
Good Luck

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

White Lines in picture


your problem is common for sanyo and fisher tv's the B+ feed capacitor is defective and maybe the waveshaper in the cuircuit right next to the IC. Your probably gonna need a service manual to find these caps as if you get one from sams photo facts post the vertical here and I will show you the capacitors to change. Done it a hundred times but I dont remeber the #s. Old age I guess. Good Luck
