Question about LG 32LG30 32 in. LCD HDTV

1 Answer

I have two problems: 1. several chanels will not come in very well - the have lines, distortion, picture is in "squares", no sound. Sometimes it is an acceptable picture but is is on for 1-2 secs, then blank for 5 secs, very little sound. 2. Finding the channels-the auto setup catagorized the channels into four groups, when in one group, it is very difficult to switch to another - it must be easier than this, but the manual doesnt address this. Help please?????

The description of "picture is in squares" is typical of poor signal conditions. It is called "blocking". The screen is made up of blocks of bits of the picture and is reassembled by the uProcessing inside the digital set. Clever really!
If you get your signal sorted out you will find that the processor will have more time to do as you request with menus and channel sorting.
Hope that helps.

Volume is a relative thing and our ear's perception can be quite different than what we expect. With distortion the spectral energy is spread out from the spectrum on the clean setting. The ONLY way you can check the output is with an oscilloscope looking at the output waveforms. The RMS output under distortion will "appear" louder as the waveforms are squared up and nearer flat-topping a lot compared to the output when clean. The amps have several gain stages and the numbers on control settings have very LITTLE meaning regarding whether the amp is near max. Only checking the output waveform with a scope will give a true picture.
You should procure a sound meter also to help in measuring sound pressure levels. There are OSHA limits for hearing protection now to pay attention to.

Samsung HDTV 1080I-Model#HCP4363W-Convergence Problem


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
