If the TV keeps blowing fuses, there most be a short somewhere. Most likely the power supply board itself somewhere. But take it to a repair shop to find out for sure. The sad part maybe that you'll have to pay over $100 for someone to look at it.

Always blowing fuse in my astron tv..why?

It is possible that the fuse is damaged (if it is an automatic one). They are prone to damage after first shortened circuit. Try to plug in your tv elswhere and see if the issue repeats itself.

No power to my tv set. fuse blow. but there is no fuse rating

When a Fuse "Blows" NEVER just replace it. One must always find the exact cause for this, otherwise there is a risk of fire or even explosion... The reason a fuse Blows, is due to a short-circuit of some sort, to earth. Occasionally a fuse may spontaneously fail... but this is rare. These types of problems must only be sorted out by qualified service man/center.

My phillips 42" flat screen model number 42pf7621d/10 keeps blowing the fuse in the plug usually after we have turned the tv off and its in standby mode or overnite when we sleep ive just change...

What is rating of fuse in your TV like amperes and volts.
There is Thermistor in TV for degaussing the picture tube while in start up. This part requires heavy current to work for a second or two.
You can increase little bit current rating of fuse to avoid blow off.

RCA D52W20 52 Fuse problem

Well you could always use a bigger fuse but I would not advise to do it, it could and most likely will blow tv not fuse. Fuses ussually blow from a short or power surge. If it is new or under warranty I would return it for replacement or repair.

Possibly a resistor that's becoming defective... it's changing value thus increasing current. like if the resistor has a rating of a 10k Ohm and now it's changing to a 30K Ohm and the current (amps) is supposed to be around .50Amps and now it's rising to .75Amps or higher, so it would blow the fuse so as not to further damage any other high voltage or sensetive component. Is the fuse you are replacing the same as rated for the tv? ie; 250V 1.25Amp FB (fast blow) or SB (slow blow) it should say on the circut board where the fuse plugs into.
