I have replaced a capacitor, transitor, and a diode as was described to me by repair world this is on the deflection board, now it turns on and works but it has an hour glass shape to the picture the side...

thats a pin cushion problem. I would check for more bad caps on the deflection board or open resistor. Sounds like you had an issue with the retrace cap CL031 and the HOT transformer and possibly the DL030 often if they fail bad enough the circuit board can actually burn through and that arc can travel and cause other items to fail. You may end up having to replace the deflection board to fully fix the issue of pin cushion that your experiencing now.

TV won't turn on

There's a small diode on the power supply board that causes this. Its identifiable by its purple stripe. You will need the correct type of diode to fix this properly. The diode supplies the standby voltage to the system control circuit, so when it fails, the TV will never come on.

TV problem

Use the analog meter reverse your probes you should get no reading one way and get a reading when the probes are reversed. You will need a diode vhecker to test for a leaky diode as often times a diode will fail under load. Its best to replace a questionable diode if you dont have an actual diode checker meter.

Mitsubishi VS-60703 60in. Keeps clicking and power light keep blinking but tv wont turn on.

This is a common problem with this set and you may get luck by just replacing this part. But of course theres never a gaurantee of this. Its a nte or ecg 598 HI voltage diode. Used as a damper or waveshaper. In this Im pretty sure its a damper.. Just make sure you unsolder the horizontal output transistor and make sure its not shorted. Now you kmust know if your not a tech and know the hi voltage saftey issues with tv sets, You can get hurt by probing in the wrong place even with this set unplugged. I included a data sheet for this dide/rectifyer . Its lockated as a PDF. All you do to see it is click on your model # at the top and scroll down till you see the PDF. Good Luck. Oh and let us know how you made out and if you reconsidered and got a pro to assist you or you fixed it yourself??
