Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television

1 Answer

Red-striped ghost images.

The set is a couple years old. When it displays images with dark areas bordering light areas, especially with dark appearing to the right of the light, a ghost image appears along the light side of the border. The ghost consists of red stripes that appear stationary relative to the image (i.e. moving images appear to pass by the stripes) but it only appears in the area along these light/dark borders. It appears in HD and SD, as well as signals through different inputs (cable box and DVD player, both connected via component cables). Adjusting the image revision didn't fix the problem.

Re: Red-striped ghost images.

When you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...

Our 57H81 is about 10 years old and we can hardly see the picture on tv/movies especially - when a dark scene is shown. Do we need to perform maintenance or change out the projection lights to get the...

You can try cleaning the lens/mirrors of the set with a lint free cloth and a cleaning liquid made for cleaning glass. The dark image can sometimes be caused due to dust on these parts. If that does not work then I am afraid that you need to purchase replacement CRTs(the three tubes at the back of the set). Each of them produce one color - Red, Green and Blue and all 3 have to be replaced to resolve the problem, unless you can visually identify a malfunction with one of the tubes(If one of tubes is a lot dimmer than the other 2).

Red-striped ghost images.

Are the stripes u are talking abt look like these? If yes these are called Moiré patterns.
Here's How to fix

  • If your system has a Moiré Reduction Control similar to those in computer monitors, then you can use it to reduce or eliminate the patterns. Just make sure, you write your default settings before you change it.
  • Some folks have gotten electronic fixes (firmware or software) from TV manufacturers but results have been spotty at best.
Slightly defocusing the image via the mechanical focus of your set appears to be the best bet. This has been proven effective in various TVs. Be careful not to over do-it though so that you don't significantly degrade image sharpness.

Words are doubled red borders???

Just to clarify, it sounds like what you are saying is that the image appears to duplicate in either red or blue along the edges of the image (especially white lettering and probably increasing along the boarder of the TV). This is resolved by converging your TV. Convergence will drift normally on large screen projection TV's over time or through moving them. The Hitachi 57f500a has a feature called "Magic Focus" (pg 36 in your manual) which will auto converge the image. If the auto converge feature doesn't work, on page 37 in your manual, it explains how to converge manually. If you do not have the manual, I have the image of the pages below. If for some reason this doesn't work, please provide additional info and detailed prior to rating the help.

Red ghosting on images that are not closeup

1. Power off -- let bulb cool.
2. Display - 5 - VOL+ - Power (in quick sequence) to display service menu.
3. Go into the user menu and set auto revision back to auto.
4. Put an image on the screen that shows the problem. I always found the edges of a 4:3 aspect ratio signal displayed the ghosting very well on my set.
5. Use 2 to scroll through the categories to find D GM TG
6. Use 1 to scroll through items in D GM TG to find V POS D
7. Write down current value.
9. Use 3 and 6 to change the value to minimize the ghosting. You should only need to move it up or down a value or two.
10. Press Mute - Enter to save the changes.
11. Power off and let the bulb cool.

PLEASE HELP (Three Ghost Images)

You will need to have or change the convergence correction driver IC's. There are two of them in this TV set. Not a fix for a novice I'm afraid. If you have no solid state repair experience, play it safe and call out a pro to assist you in this repair.
