My Toshhiba 53H71 went black and the red power light keeps blinking. Is it worth repairing.

the light indicates an internal electronic fault with your set
projection TV`s have integrated protection circuits
built into the circuit design, these circuits turn the
power off automatically when a fault has bin detected this
is in order to prevent a more costly repair, these circuits monitor
power supply , vertical and horizontal deflection
over voltage, or x ray, and also faults with convergence circuits.
Diagnosing these faults require test equipment and a good knowledge of
electronic repair techniques, and also a repair manual.

Any indication of power? red light? blinking light? Sounds like the power supply failed if no indicators on. 3 yrs is an average lifespan for these new sets.... unless you are a tech, it's time for a repair shop. Get an estimate first, sometimes its not worth getting an old set fixed...

Had the same problem on my 42in. and it ended up being 2 of the fuses and 1 board had to be replaced.About 900dallars worth of work,it was covered under warr.

Replace the convergence ics.

I am in the same boat as you are. My wife and I had watched the Steeler MNF game yesterday evening and today when I went to turn on the Pens game, all I got was a blinking red light and a "power on" sound...wtf...Can anyone help? I'm definitely not a techie nor have I ever soldered anything...

Most likley a convergence board. remove the back pannel to find the chassis number to order a new one. Wouldent hurt to check all fuses while your at it

Either the convergence or cracked sautering. Just had my tv repaired but now I have a double blur in the upper left corner.

omg.. i have the exact same prob...
is it a conindenice that we are all having the SAME prob around the same time?

Look carefully at metal jumpers feeding b+ to convergence IC's.

Both will need re-soldering or you will keep having problems. 

Let me know how it goes.T.
