Hi I was not sure if the line was going from top to bottom or left to right. the X driver board is for left to right and the Y board is for top to bottom . The Y driver board is a common issue with these sets there is a Y main board and a upper and lower buffer board for the Y axis

Hi and welcome to FixYa,

Initially, your description could possibly indicate a single line. This is almost always caused by the failure of the vertical deflection circuitry. More often than not, it would be the vertical output IC.

Good luck and Thank you for using FixYa.

    This is a relatively easy repair and should take no more than 30 minutes to complete the job. Parts cost would be in the neighborhood of 10~15USD. Service fee would be another matter. However, if you have experience/comfortable with a soldering iron or know of a buddy who is, then it would be to your advantage to have it repaired.

    Cheers.

Sanyo DP46848 im stumped lol... with nothing connected ( aka ) cable and or any other components .. just plug and turn on .. the screen has a solid blue bar from top to bottom with small white lines in...


Although you have not posted a picture, I believe you may have a screen or LCD panel problem, the panels have film connections that go from the t-con module, through the panel control pc boards then through thinn film connectors from the lcd screen. Likely this is the problem.

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.

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!

Picture goes to one thin horizontal line in middle of screen


There is a bad solder connection in the vertical sweep circuit. if you know how toi solder, go and find the vertical output IC and resolder that first.. but if you have no solid state electronic repair experience, please find a trained tech to assist you in this repair, as if you wait it may end up costing you double of what it would now, so haveit done ASAP. Good Luck Please do not forget to rate this one.
