Why my LG model VS81099 keep shutting off


Ive had the same thing happen. Its mre than likley the power supply board. I put the model and brand name in electronics on ebay and typed in power supply board. Cost me $25. Its pretty easy to get to and its usually right in the back of the TV if you take the cover off in the back. Im not sure if your a tinkerer or not but its cheaper than a new TV.
Hope this helps

Shuts off and on while trying to watch, the power light flashes 30 times when off then the tv comes back on again


Power supply trouble. The TV keeps trying to start then operates for 2 seconds and shuts down. The cycle keeps repeating until eventually the TV will not start at all.

Tv goes blank while viewing


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that re-starting that gives it away, this is a typical switchmode Power Supply problem.

Static shock when we turn tv off and it went blank


Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Consult your technician there is a semiconductor problem inside your tv. Probably lose connection, and need to resolder.
