You have a vertical output problem,take something insulated and prod around board and see if pix starts to flutter,then you could have a "cold-solder" joint,otherwise its more than likely a capacitor between the vert driver circuit and the vert output circuitry,

Sanyo flat screen tv about 2 yrs old has thin colored horizontal lines down the right side


Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

A horizontal thin black line has appeared across screen.


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Sounds like a failure in your vertical deflection circuit. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Insignia 32" Tube TV NS-RTV32


The vertical output IC LA7847 is failing. It will likely fail permanately and you will have just the horizontal line. The set will require service. Just do not run the set very long in this state. That thin white line can likely burn into the crt phospher and will show all the time thus ruining the glass picture tube...

POP and noothiing


yes it can still be fixed! the pop sound you've heard maybe came from a blown capacitor in the vertical deflection circuits. 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!

Horizontal 'pinstripe' lines on all channels


sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.
