[sdiy] TX802 Power Supply failure (replacing 3W with 5W resistor)‏

I agree with Colin.  It's much safer and quicker to just replace the 
whole PSU with a modern alternative, unless you enjoy the challange of 
fixing a SMPS and the excitment of unexpected explosions!  There's also 
much less chance of you doing further damage to the TX802 with a known 
good replacement power supply.
