Hi


Thanks for using FixYa. To check what has gone bad you’ll have to open the back of the unit and check the backlight inverter board. The inverter is the power supply source for the backlights and is normally supplied by a dedicated voltage from the power supply (24vdc).
If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. If not then check the power supply board however, it seems to be the inverter board as the sound is still working fine. If you have some electrical expertise and know how to use a voltmeter then you can do it yourself, if not then its good to take assistance from a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Hello. this is a common problem which may be under warranty. The cause of your symptoms is usually a poorly soldered connection on a circuit board. This can be difficult to locate unless you have good TV diagnostic equipment. Begin by checking on the warranty because working on it yourself will void any warranty that may be in effect. J.

Sony bravia 52 kdl xbr ghosting


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.

My zenith sentry tv has a double image on the words that come on screen. The people are clear but all wording has double images


Hello
Double images are technically called Ghosts, occures due to the setting and direction on the antena. You have to reorient your antena, in such a way that Ghosts disappeares from your screen. The reson for this fault is not with the TV, as it gets a direct transmission signal, and a reflected signal of the same, reflected from near or far objects, like tall buldings, hills and so on. The signals, the orginal and the reflected, will be processed by the TVs internal ciiruit, and the first will appear as strong picture, followed by the second, a weak picture, will be seemed as an image of the first one, just on the right side [view point] of your TV.
You just adjust the position and height of your antena, looking the picture, where there is minimum Ghost level is. No other repair should be done to your TV, as it is perfect, and you just give it only direct signal path. OK.

Visio 32L color goes bad with ghost images after about 5 minutes.


This sounds like one of the two things that destroys electronics. Heat. You can try this. Place a fan blowing into the vents of the set before you turn on the set. See if the set run longer before the problem occurs.
You may have a marginal part or bad connector/connection.

Double and curved image on blue warm-up screen


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Picture won't come in clear until TV "warms up" for 15 minutes or more


Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.
