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!

Sound no pic. after on for 20min then turned off back on and pic. now it will not get pic just sound


Your TVs CRT socket is faulty. CRT socket is one that connect the base of the picture tube, and can be located on the base card of the tv. It is soldered directly to base card and can be replaced. Unplug the base card from the picture tube neck [Caution: never damage the neck of the picture tube. Only slight pressure should be applied], desolder it out and replace it with a similar type.

Turn on pic turns red with thin bright red horizontal lines


Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.

I think your picture tube is weak.
You can verify this by taking the back off and slowly adjust the the screen control (it is mounted on the flyback transformer) the one with the wire coming out the top and going to the picture tube
the lower one. it is black and serrated and less than 1/4" in diameter.
turn counter clockwise first then advance it while someone watches for the picture.
If it comes on you know the tube is weak.
it may last for a while at that setting, but be prepared to buy a new set.

In picture number 2, I saw some blue also. So I'd guess that the red gun is not firing. This could be a transistor on the board on the back of the picture tube, or it could be a bad picture tube. I would replace all three transistors on the PC board, if the problem remains, it's probably the tube.

Hope that helps...

Picture tube doesn't seem to stay in place (standard tv)


A very good chance this tv was dropped or bumped. Sounds like the internal plastic frame is broken and will not support the picture tube. Find someone with tv experience to fix this. I would suggest they use a putty found at an auto parts store. To glue the tube and the frame together. This putty is in a plastic tube. You tear off a piece and fold it several times to activate. It will surely do the job.

My tv has a bright grrn tint


Is there a color button on your T.V? Maybe someone bumped it. You know, like on the old Macs. I know your tv is new, but there might be a button. check.

Picture improvement


I've heard that the P52 can give blurry pics, however I don't quite know how to fix that. You may be able to do something with a software program (ie Photoshop). Since I can't help I'll bump you up so someone who can help might see this! Good luck!
