Hi there!
This is called a frame collapse. The Amp that drives the vertical sync has failed. This could be from excesive voltage on the mains, Lightning in the area, if you had or simply general failure. May also be dry joints( or loose connections) in the vertical amp or scancoil terminals. Good Luck,JUS004

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.

Old sony tv gets a bright line in the middle of the screen


Well if this is a tube type, it can be attributed to vertical section. Cold solder on vertical IC, the vertical gone bad or some components on the vertical is at fault.

If your not on electronics better to have it check by a repairer.

Hope this helps.

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Flickering multi-colored line in the middle of the screen.


You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

Sanyo 25" Standard Tube Vertical Deflection Problem


you can proceed as follow to fix it.

  1. reduce brightness to minimum to avoid screen burn.
  2. check voltage on vertical uotput
  3. check yoke connector for loose.
  4. check v/yoke winding.
  5. check v/drive from signal processor to vertical output

now your problem how to find out whether drive is there or not it is very simple even you donot have scope.

you simply touch with screw driver or meter prob  at the poibt where vertical signal is input to vertical stage

if h/line is spreadindg or tries to spread then your output is ok &problem is in drive ckt.

for schematic try given site give model no &download it

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!

Sanyo TV model DS25710 or DS25730


Set has a bad vertical sweep IC. Also This Sanyo has a tendancy , when the IC blows out , to take the fusable resistor in the sweeo supply that feeds the vertical IC. This set should only be serviced by a trained technician because of ther high Voltage that lingers within. This repair should run you antwhere from 85.00 to 150 bucks. Good Luck
