Iam living in the country of Barbados and i saw on the site The Blue Ring Tester. I was wondering where i can purchase one. What would be the overall price. For shipping and handling to my country(Barbados). Do the store take money orders, and approximately how long would it take to reach me. I know that Christmas is around the corner and things would be hectic. I appreciate all you have done in the past months for those newsletters. They came in very handy and once again i thank you and wish you and your family all the best for 2010 and looking forward to a great year.

Thought I would share how much time this tool save me today.I had a 32" TV with chirping SMPS transformer when you try to turn on, no HV(High Voltage), only chirping continuously.Because of working with this TV model before I suspect problem in Horizontal circuit.Using your technique I first use ring tester on flyback primary winding and it checks shorted,next step I desolder pins to primary winding and make sure they are nicely cleaned and "floating"(not touching sides of hole in trace pad), checking primary winding of FBT again desoldered from board lights up all light of ring tester, flyback is good so I know I have shorted component now in the horizontal circuit.First thing I suspect is the H.O.T.(horizontal output transistor) I remove and check, it is shorted between all pins.I checked all other components in the Horizontal circuit including damper diode safety capacitor etc....but found know other faults ,however close inspection of the PCB let me see that the horizontal drive transformer had developed bad ring cracks.soldered the ring cracks, put all the components back in place, except for the H.O.T. which I brought to my shop to order replacement, which I am confident will fix the TV, the point of this story is the trouble shooting time was only 10-15 minutes, thanks to having the right tools for the job like the blue ring tester.
