SOURCE: Hi there I have a Sansui LCD model sv-46lcd tv
The signal boards will do this and is a common problem for this set!
SOURCE: Hello have a problem with tv Model is: lg
http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281
The above link goes to lg's website describing the red flashing light where the power switch is, and
another switch down below which can turn that light off.
Try switching that other switch below off so the light turns off. Then, switch it back on.
If that doesn't work, then service should be scheduled for this discontinued model.
Hope this helps on your lg tv.

Check the site linked below. As stated above, three blinks are the symptom of over voltage. If an over voltage comes out of the secondary side of the SMPS power board inside, this type of indication will occur. You have to troubleshoot and repair the main power supply regulator board. In most cases, it might need replacement, as components to this board are not easily available in the open electronic spare part market.
