Ghosting problem with 71 model lcd - Televison & Video

Michael, does the ghosting go away of you tap the set? Or if you turn off the set and let it cool off and turn it back on, is the ghosting still here? One of the most common causes of ghosting or double image problem is due to a defective LCD panel tab. Sony's are known for this problem. I would recommend getting a diagnoses done on the set to be sure. If it turns out to be a LCD tab problem, the only true fix is to replace the panel.

Hi,
Ghost lines or distorted lines is problem of lcd panel. Main board is working fine without any problem.
LCD Panel replacement would cost you new tv price so its up to you to replace lcd panel in this tv or buy new one.
Thanks.

There is a specific method for ghost adjustment on the 50v500.

Ghosting is most noticeable on lettering or with the set in the 4X3 format the edges will look somewhat double or have a ghost.

If this is what you have: I have the process which is done with the Hitachi remote to correct this. I got this from Hitachi who published a service bulletin on this problem for this model.

Hi,

First,If there are double images or "ghost" images on the TV's picture, check the cable connections and make sure they are secure.Because the loose cable connection would be a chance for the ghost picture

But if the cable is perfect and if you still get ghost picture then here is the solution:

The LCD Panel is defective. The problem is the T-con board that is used to decode the signal from the main board to the LCD Panel. The only way to fix it is to replace the whole LCD Panel or T-con board if possible. The T-con will cost about 1/10 of the price as the LCD panel but except for a few new models, the T-con is not available. The LCD Panel is very expensive (usually from $600-700 for a 32" Sony).

The reason is that Sony makes the T-cons for each individual TV with different specs to match that of the LCD panel because of the low threshold for error between the LCD Panel and the T-con.

Its best to avil warranty and change the panel...

Please leave me comment, if you need furher assitance

It is fixable depending upon the make and model.

The digitizer function reads from the input of the LCD touch screen, so I would say LCD.
