Hi, Elgin.
If it is onlt the power supply that is causing the issue, then it can be repaired fairly inexpensively.

However, alot of times, it might seem like it's the power supply, unly to find out that it is in fact bad capacitors that are causing the failure.

If it turns out that the capacitors are going out on you, then you may want to consider a new tv, as the cost of repair can sometimes be very expensive to fix.

I have seen tv's get repaired die caps failing, and after it was all said and done, they could have just went out and bought a brand new tv, for less than the cost of the repair itself.

The reason capacitors fail is due to poor manufacturing quality, be it workmanship, cheap casing material, improper formulas for the capacitance gel, poor quality welds, low quality solder, or just the fact that the parts are sometimes made in parts of the world where profit is the companies only concern.

From around 1995 until 2006 or 2007, there was a flood of these cheaply made capacitors, and they were put in everything from toasters, to subwoofers, car stereos, computers, microwaves, blood pressure machines, and on and on.

High quality caps should last between 25-40 years, but these cheap ones are sometimes lasting less that 1 year before failure.

I hope this gives you some ideas about your tv, so that you can make a proper decision on repair or replacement.
