Red horizontal curvy lines

    Thanks so much. Your instructions were very easy to follow and understand. Worked like a charm. The voltage adjustment was very sensitive and hardly turned it. I tried the focus, but it didn't need any adjustment. Picture looks great. Like new. Thanks.

You need to turn the voltage on the red tube down slightly, also you would need to adjust focus to compensate for the lower voltage to the red tube. On the left and right bottom side of speaker cover are two round covers, take them out and there are 2 1/4" hex screws take them out carefully take cover off, there is another service cover same hex screws remove. You will see the focus block on the right side, tubes are labled on block. 2 knobs for each tube. Make voltage adjustments while tv is on a black screen, then for focus, turn color all the way off in the menu, and adjust focus until it looks right in black and white. These adjustments should only be very small; if alot of adjustment is needed, you may have other issues.

Faint red curved lines on Sony KP 51ws500.Converged = no work???


Hi There!
This sounds like a typical problem related to a older CRT.
If you remove the front cover of the tv, you can then remove a wood panel. Behind this panel you will see a block (high voltage splitter) it will have 6 "knobs" on it, 3 will say focus, 3 will say screen.
They will also be labeled R - G - B  
Put the tv on a blank input so you can see the lines clearly on a black screen  - Find the knob for red, and SLIGHTLY turn it down until the red lines disappear.

Screen turns red after 10 minutes


First, lets see exactly what is happening and what is causing it. If your picture starts out fine, and after 10 minutes or so you notice that the picture is getting redder, and the redness slowly gets worse and worse, until finally there is red everywhere with faint curved lines, then chances are your Red Screen control is set just a hair too high. This is a very simply thing to correct. If, on the other hand, the picture is fine for 10 minutes or so and then suddenly flashes very bright red, followed by the set shutting down, then your red picture tube has developed a short in it, usually between the heater and cathode. A good tech might be able to remove the short by arcing. What is your set doing? The KP-51WS500 is one of the newer 16x9 1080i HD sets and the tubes are available from any Sony distributor. When they told you the tubes are not available, that was their way of saying they do not want to bother helping you. The Sony tubes are quite inexpensive, costing about $175, and they come complete with sealed coolant chambers, so replacing a tube is quick and simple.

Horizontal Lines


sounds like you are seeing retrace lines. you will have to adjuste the screen control. (it would be like a master brightness.) you will have to removed the front bottom plastic from the tv, look for 2 to 4 screws. then gently remove the front. sometimes the also add velcro to help hold it in place. now you need to remove the small plastic or wooden panel/door. in the upper right side you will see a small box with 6 controls.i do nor remember if the top 3 controls are for screen or focus, use a flashlight it is marked on the box which is which. adjusted the screen control to the left slightly to decrease the color you need. the green is the center control. like you said it is more noticable on dark screens, so try & adjust it in a dark romm with a drak seen. good luck.
