Sony KP-51WS500 tv went red screen on me it has 4 blue lines going across also has blinks 6 times.. what do you think this might be..

Off hand I would con dim the Red and Blue CRT"s. If you were to replace two of them I would also do the Green CRT as well. The cost of just doing two of them is way too expensive in my opinion and you would be better served to replace the set instead of investing the amount of money needed in a 6-8 yr. old set.
Hope this helps,

Red horizontal curvy lines

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.
