RCA Model# HD56W66


If you do not even get the power light to come on-start at the beginning---follow the power cord into the set and look for the fuse--this is where to start.

Let me say something to you? I am more than happy to help you--the reason I am here.

If this set had a shutdown problem the light for power would still come on---The typical resolution is to start where the power (120 volts ac comes in) and see what you have.

All these sets are very well protected--if you had a power outage or lost power and do not even get a click or the power light coming on you may be a lucky person---a completely dead set is better than one that has the power light on but does not work.

Let me know what you find--ask me questions--I am here to help but the more you can tell me the better the chance I can help you.

If this helped you rate this solution as I do this here for free.

Remember: Any questions let me know.!!!

Distorted Screen for RCA HD56w66


convergence is the problem. first question do you have convergence in the customer setup menu. if you do not it could be a special small fuse if you do have "convergence" in the setup menu then you most likely have a convergence power board issue. and generally they are replaced. in our shop such board replacement average 124 labor and about 100 for part. if the fuse bout 15 for part and 80 for labor. there are solder connection that cause the blown fuse

Neff combi blown diode.


If the diode failed by opening, there may be no other damage. If the dioded failed by shorting, the alternating current may have damaged other components. Ohm it out. You can get diodes from digikey.com, mouser.com, or radio shack or any electronics or appliance supply. If the diode is charred and you can't get the part number, the oven rating can be used to select a replacement. Since the fuse was 10 amps, the diode should also handle at least 10 amps. If you can power the unit and read the voltage at the diode input this will give you the power (volts times amps). It's always worth trying as it's cheaper than replacing the unit.
