Thats something you would need the service manual for to be able to see which part is malfunctioning. I would recommend going to the following link as they will most likely have the service manual for your model which they sell very reasonable and it comes with free tech support so you acn go one on one with a repair tech that will help you get it going. If you dont see your model just leave them an email as they most certainly can get it. They email the manuals out instantly and support is handled my on line instant messaging. Its a good service I am one of their support techs. here's the link.

When I turn on the TV, the picture is fuzzy. After five minutes, the picture is clear but any words are out of focus even the menu for adjustments is out of focus. The convergence for red is clear but...


Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

When cable hooked up picture ok a little blur but when dvd or ebox hooked up picture is great. what can be done


It's probably because your standard cable has lower resolution than your DVD player or Xbox console. If you're going through a cable box and can eliminate that (depends on your TV and cable system) that might help, otherwise you would have to upgrade to hi def cable to have comparable resolution... hope this helps.

No picture - only sound


Ok, on a hi-def tv, you must have a converter box capable of receiving Hi-def. If you are using a converter box from a satalite or cable tv service, try getting a Hi-def box. Also try hooking a vcr or dvd player to the tv in the non high def ports to varify that this is the problem. If you have any question please let me know, I hope this helps, good luck.

Hi, the capacity of your TV is not good for Hi-def.. the resolution of your TV should be equal or less to the capacity of your TV. See the manual for the best resolution for your TV

Hi-Def?


Yes, it is HD TV ready but you must have a set top box from your cable or dish company that provides a Hi Def signal. The inputs must also be connected with the YRB cable. Only certain channels on my box are HD. The screen is so large that HD isn't nearly as impressive as some of the smaller models but it is still HD. I also have the 53FDX10B.

No picture when cables connected


Go into menu on cable remote and open up 480p,480i,720 and 1080 . I think on some of those 1080HD only works on one of the two component inputs. The other is only rated for 720. Usually it has this info on set at input. Hope these suggestions are helpful.

It's not a digital hi-def tv, so you either need a cable/sat box..or a converter once hi-def goes in and analog stops.
