Great picture no sound

This sounds like the power supply went out. If you have an indicator light on the set and nothing else works. It could be the bulb though

in the model listed the set will "turn off" the tubes if No High Voltage, a vertical or horizontal circuit loss of sweep etc.

Need a schematic and a meter to start checking things.

alvintowns,

Your convergence is not working. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to repair it and where to get the parts.

Thanks for using FixYa and for the great rating.

the static sound may be due to a defect in the high voltage circuits, IE Fly-back transformer or and voltage multiplier, posibly high voltage leads to the CRTs arching to ground, finally horizontal sweep circuits

It sounds like your looking for a CRT (red) the part # is on the CRT and could be puchased through any Zenith (LG) distributer- usually around $300- $500. Google the part # when you get it and you may find a used Picture Tube (CRT)for cheaper.

buttons are probbaly old......how old it the tv??

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*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
