If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Horizontal output possibly shorted, &, or voltage regulator, could also have bad caps in the regulator circuitry, & resistors. Pix tube can also blow the power supply. You'll have to do some troubleshooting to locate any bad parts, bare minimum you'll need a decent multimeter and soldering equipment.

You may have a surge protector called a thyristor that is shorted right on the main a/c line. Or the main power supply has a major nasty short as the bridge rectifier the filter cap or the degusing coil.

Tv is pluged in,will not come on when on button is pushed

is the unit competly dead? no flashing lights.first unplug the set for 30 min then plug back up and try again if there is no lights then i suspect main fuse has blown. however this does not mean replaceing will fix. something has shorted to cause fuse to blow if there is flashing then the computer in the set has seen something wrong and shut down.

No Power

all sets must have rated fuse for protection. some units now use what is called a PICO-FUSE.this type of fuse is soldered into the pc board. usually marked with location i.d. F301,F901,F400. etc. these fuses look like resistors or in-line coils. check continuity w/ohm meter. if new fuse blows as soon as you plug in tv, suspect bridge diode ciruit or main filter cap(large ripple filter by main fuse. if new fuse blows when you try to turn on, suspect 130v regulator or high voltage short(horizontal-output, flyback transformer) good luck!

Blowing Fuses

main rectifier could be shorted, main regulator could be shorted MOV surge supressor is probably shorted. MOV will be a little disc close to the power cord input (after fuse).
