White lines across tv screen

Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:

If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.

If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.

If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.

A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.

Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!

There's a very narrow line (white) appears at the very top of the screen when the picture scene is mostly black. A verticle adjustment should fix it but where is it?? RCA F36TF720

it may be an electrolytic cap problem as most newer sets are controlled by an I.C. chip for horiz and vert timing/size/linerity

Rca 32 inch tv

this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

Screen is bowed on top and bottom.

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.

You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out 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

RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again? Please contact me at

The vertical circuit has failed. This can be as simple as poor connections on the pins of the vertical IC or a defective IC. If you can solder, you can fix this yourself. Let me know if you wish to attempt the repair and I'll provide details and instructions.

Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.
