Ghosts on my tv

I am having ghosts (shadows) on my tv? It is hooked up directly to a cable box. We have unhooked all boxes to try to eliminate the problem. Ghosts/shadows remain when everything is unhooked. Help!

If you can, try hooking up the tv to a different cable line in the house or bring a different tv into the room where the bad picture is [ you may have a bad connection or wire ] if this doesn't help, try rabbit ear antennas just to get a picture. if you still have ghosts on your tv, the problem is with your tv.if the picture is fine, there maybe a problem with your cable service.
hope this helps

Colored ghosts (red,green,blue) is convergence bad. If can't adjust from menu, then bad circuits. Call someone for approximate estimate.

Ghosts


How old is ur tv...? Cos the wear & tear is the cause for this ghost appearance. The repair for this is only temporarily. It can not be eliminated completely.

Generally the blue ad yellow colour can be removed by a tool which is available with a tv technician. It is not very expensive to do this. Hoping to hear from you.

Thankyou

Green and purple ghosts


Try to reset first if nothing happens we proceed another solution;

Resetting the TV

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can saved time.
1. Unplug the TV power cord from the power outlet for 3 - 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

Floating lines in picture


"Floating lines" usually caused by bad cable signal. Try playing a dvd or tape. If lines are gone, tighten all cable connections. If lines are there, you could need convergence repair if any colored shadows or ghosts are visable around on screen lettering. Hope it's some help anyway.

Sony KP61HS10 and timewarner digital cable box. Don't know which is the problem. Problem is a blue/white ghost on all channels. Tried unplug both units, tried flash focus. Shadow/ghost is now curved image...


I'm going to guess that these ghosts are of different colors too. This is most likely a convergence problem. Try resoldering the pins on the convergence ICs first. If that fails, replace them.
These ICs are large and black, attached to a heatsink. They will be marked STKxxx.
Keep us posted.

how old is the tv ??
if this tv is older than 5 years it may need to refill the liquid on the proyection bulbs and/or could have contaminats in the fluid causing the ghost and to fix that you will need a professional person to do it

try replacing the convergence ICs and also check the resistors that power them. This is a common fault with all projection TVs.

Sounds like a light engine issue to me. Is there anyway you can post a picture of the issue itself?
