Red horizontal slightly curved lines on dark scenes. Sony KIP-57WS500 Rear Projection TV 57".

Blinking 5 times is a sign of at least one of the three video tubes overcurrenting, which will eventually shut off the image. It happened with me but with my red tube over-illuminating. The solution is to reduce the drive intensity on the offending tube. Remove the front speaker grill. Behind it you will find a panal with 6 pots, these are drive (brightness) and focus for each of the 3 colors. My fix was to turn down the red intensity to zero and (after a restart) bring it up slightly till the image was acceptable, colorwise. I did have to adjust all 3 intensities to get a decient color balance along with the focus's on all three tubes (the drive intensity adjustments will knock the focus out as you go). I used the auto-adjust patterns to focus on, and you may want to use a stationary image, such as a paused DVD scene or a video game, to focus on. I still haven't found a way to clear the error code, but I learned to ignore it. The result isn't perfect, but it's very acceptable and it'll do for awhile (and it didn't cost anything!). Good Luck.

You have 3 CRTs inside of your TV that create image. Blue, Green and Red. Looks like one of them need adjustment due aging.
Remove front grille. Than remove center "shielding" piece held by 4-5 screws. Behind this cover you will find little black plastic box that have 6 rotating buttons on it. Take you time to study them. There is three columns and two rows. Columns represent color, rows - "Focus" or "Screen". You need to locate "Screen" row of three rotating buttons. They will be marked "B', "G", and "R" for colors accordingly. Turn on TV let it warm up and try to figure out witch color is dominating others on your screen. Then carefully turn rotating adjuster counterclockwise using Philips screwdriver. Try to muscle-remember original position of screwdriver so you can turn it back to it.
Eventually you will find the right one, you will see lines dissapear when you reduce voltage and reappear when you turn rotating shaft back. Sometimes more than one have to be adjusted.
Try to have all three color to be present and visible but with no over saturating and no horizontal lines.
Put cover and grill back - and that's should do it!

common problem with sony, focus and picture level need to be adjusted, should be done by a tech. (high voltage) in focus block.

This is convergence out ICs failure and will be replaced for correct picture in TV.
Let me know if you can solder parts in circuit board of TV with necessary tools to provide you IC number and store address, or call local TV tech for fix if you are not comfortable with TV repair.
Thanks.

The green picture tube has an internal short. Happened a lot with that model. The tubes are no longer availible. But a reputable company called Video Display will rebuild the tube completely. But the tube must be pulled and shipped to them. Most repair shops would charge around $400 to $500 for the complete job.

You may have a few dead pixels, or maybe it's leaking. I suggest you replace it.

Look around this sight the answer is explained here. you hace to take off the front speaker cover and a small panal undder it. you will find six knobs on a small panal. use these to adjust the settings fotr the power and they will remove the lines. You will need to have the tv on and I would sugest a normal size phillips head screwdriver not a power tool.

Probable convergence IC failure = replace both for reliability..T.

Correct ! One set is for RGB focus and the other set is for
RGB screen voltage............................T.

Sounds like a conergence circuit failure, probably a couple of AMPs and a few discreet components. Probably 250-300 repair
