No sound and no picture

The green indicator merely lets you know that power is getting to your TV. The absence of picture and sound could be due to power supply failure

I have a 46" Sanyo

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

I have a Model DX-R24TV suddenly it wont come on green power "on" light flashed and now I hear clicking inside what is it and where can I get parts?

The clicking noise you are hearing can be from the HT power section. The Main power is trying hard to switch on the set but the feedback signal is missing to the SMPS-switch mode power supply- that makes the protection to cut and power. You will need to check onthe EHT, the line output transformer, the EHT driver transistor and the allied ccircuits for any short which is making the +B cut off. check onthe high voltage capacitors, the vert output also for any short. replace the shorted component. The spares must be tried for availability in the nearest spare shop. If it is the EHT you must check and decide with the price of a new one. I hope this helps. Good day
