Have sound but no picture

its in your setings on remote to change pitcher around.

You probably need a new ballast.It is a high failure part.If you listen at the back of the set you can hear the ballast make a short buzzing noise every time it tries to light the lamp.If you don't hear this then your ballast is probably bad.

Just, Because you removed the battery connections and reinstalled them
will not repair a bad battery conection. Sounds like you have a bad conection at the battery. You'll need to remove the battery ends and clean
them with, a wire brush or a battery cleaning tool. Always, remove the NEG
conection FIRST,then the POS. After cleaning install the POS FIRST,Then
the NEG. Also, I believe there is a small conector on one of the cables.
Be sure to clean that conection also.
You, did not say if the lights are working.

I dropped my camera and thought the autofocus broke. It turn out that it swithed from autofocus to manual focus. There's a switch on the lens. Check if that's your problem too.

sounds like you have a bad optical block, very costly but the manufacture of these is LG and they have a recall program on certain problems is this model you may want to give them a call and see if yours might be covered.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Fuzzie picture -meaning out of focus? Check that you have not got 1- macro setting on [setting symbol looks like a tiny plant] or that you have a low light setting which menas it is taking long exposures. Aslso the Auto foxus may not be function as it should - one possibility is that the way you hold the camera covers the 'window' make sure your fingers are aware from any of the front top panel 'windows' When you depress the shutter part way down- does the lens 'motor' to focus Or indeed are you doing part way or are snapping off shot and giving the camera time to focus? Lots of thing for you to check out, before we start getting worried. The difficult ones are if the camera has taken a knock and the lens mount has become dislodged But do all the check first and do consult the manual

have a tech check your tv it needs to be repaired the tv could have some cold solder in the diffrent circuits.if noytthen it will need a complete repair.

Is very possible your picture tube is good,the problem might be a loose conection in the main board,the circuits to check will be the horizontal driver transformer,the output transformer and all overheated components in that area,another possible reason might be a loose conection in the crt board witch is in the neck of the picture tube,if you are familiar with tv service you can try to repair it yourself,you can start by removing the back cover and try to tap on different areas of the chassis to see if it reacts ,do this with a wooden or plastic handle(not metal)and be atentive where you tap when the set reacts so you can go back and check the solder conections,if you are not too familiar be safe and call for help from a servicer.Let Us know if you need more information.

You might have loose conections on the horizontal driver or output circuit,do not use it like that or it will go dead completely and is going to cost a lot more.If the set is older than 5 years it might have loose conections in the power supply too.Call someone qualified for an estimate.
