Your front panel is shot. This is a serious problem for your set and you, if you do not have warranty. This can be very pricey to have fixed, because of the cost of the part. At our shop I have seen some manufacturers with some sets just have the whole TV replaced because in there eyes it was just as cost effective to replace the whole set under warranty.The front panel or display is the most expensive part on the new TV's. Sorry I'm sure you did not want to read this. Get a second opinion, I hope I am wrong in this case.

My has a double picture with a red ghostly picture in the background. Any information on how to fix the problem? I have changed the cables, viewed the different colors, tv input, and looked over the menu....


Hello,
It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.Please run the convergence feature on your TV. Its giving you duble image because the red, green, and blue guns are disaligned. By running convergence it will realign the guns properly. You need to run the convergence feature at leat onece a week. Please note this is only for CRT rear projection tv's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to. Please refere to your tv's manual on how to do converegence and how to overlap the crosses because every CRT projection tv is different.
Good luck

I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...


The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

Red area/red line on tv screen


Odds are it is your convergence chips! If you have any colors out of alignment, thats what it is. Also if you had a speaker too close to the Tv it can cause colors to shift. There should only be 1 mirror. IT would have NOTHING to do with your problem. If you are only have problems with the red, just replace the one STK chip. They run about $20-30 on ebay. $5-10 if you buy china made. Usually the cheap ones dont get along with sony.

Red lines on Sony KP51HW40 Rear projection TV


Yeah, seen that more times than I shoulda in the last 4 years. The red picture tube has a cathode to heater short. That means it's no good. That red picture tube is no longer availible. But all is not lost. There is a company that rebuilds those tubes reasonably. Most reputable tv shops will know this. The ones I've done cost around $450 out the door. One minor hitch is that with all the shipping involved the job usually takes about three weeks. That can be expidited but then the price goes up.

Dave, HMMMM Dual pictures This is a problem that every projection TV runs into at least once or twice in its lifetime. Its the old convergence IC falure thingy. These IC's go bad and should be replace all at once. These are not consumer replaceable unless you have had training in the electronics or TV repair fields. Please call out a pro to assist you with this repair as A TV is not the place to experiment in because of the HI voltage and saftey issues. Good Luck
