My EV 700 screen picture is condenced has one bright clear line in middle screen and two more lines faded,space in between lines

I hate to give you bad news but about 90% of the time horizontal lines come from a bad panel and if that's the case the set isn't worth fixing as a panel costs hundreds of dollars

Dull Video...

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Convergence

* Screen Looks 3D, Warped, Distorted, etc
* Colors do not line up
* TV may shut off - and make a chirping sound.

It is a bad unit. If it's new, get it replaced, there is no repair for this problem. Hope this helps.

This is usually a bad elect capasitor or a bad solder connection on the vertical IC, The capasitors will be close to the vert chip..Sometimes you can clear problem with a light tap on the TV, if so then suspect bad solder.

That sounds like simple ring-cracks in the vertical circuit, most likely the vertical Ic itself... On the printed circuit side of the Tv look at the vertical Ic and examine it carefully under some magnification where each pin of the Ic solders to the board. See if you can find any cracks in those solder connections.

The 20F530T uses the relatively newer ITC008 chassis. If the picture collapses down and only a small bright line is visible, it means that your vertical output IC has stopped working correctly. This could be due to a defective IC, cracked solder joints on the IC or the power supply that feeds it. The IC should be replaced or resoldered and/or the vertical power supply restored by an experienced tech familiar with the new line of RCA TV's.

Hello, please check the 10uf/200V capacitor around flyback transformer. Best regards, Arpi

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!
