27 inch Mitsubishi tube TV

A tv that old isn't worth more than $100, The part could cost half of that or even more depending on the exact model, definitely not worth it. A tv that size is a decent price today, Just buy a tv that can get a digital signal and you will be set for next year with it. Let me know if you need anything else

Standard TV-Auto shut down

TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
However, my experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at
Hope ya fix it!

27 inch tube tv won't stay on

You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.

Red line

as you said, this is a scan problem, but maybe not from the 'board' itself but maybe the flex cable. sometimes it becomes loose and it makes a bad connection between the panel and the board. if the tv is under waranty: please call LG service customer they are very friendly and thay can give you a reference number that will get you a free repair in an authorized LG service center... anyway thats the way we work around here (qu?bec,canada). let me know
