We had apower outage in our area and when it was restored the LCD panel on the microwave barely is visible. It looks like it is working at 30 Hz when it should be running at 60 Hz. If you push the screen where the buttons should be, the oven will will work fine. Any suggestions? This is a Dacor model DMT2420S, about four years old.

The power outage may have been accompanied with a power surge. That can happen with lightning strikes, or if a large inductor (electric motor or equivalent) happened to be on the same power line at the time of the outage. There's a good chance a surge took out the control panel.
Hi Gary, thank you for your post! Often if the display LED's
are dimmed, it is because the issue may be related to a communication error
with Main Control board or a potential wiring failure. Regrettably, this is not a simple DIY job. I would strongly recommend
connecting with a professional to narrow down the precise issue before
investing in parts that may or may not be the root cause. You can often locate
a qualified service provider through the manufacturer website.
It's most likely the low voltage transformer that's part of the circuit board or a blown trace on the board. The HV transformer would only burn and smell if the unit was in a cook cycle.
The complete board assembly is only around $80. If you're really handy, you can order just the little transformer, but you'd have to remove (unsolder) the old one and install (resolder) the new one on. The circuit board is one assembly and it takes all of 30 minutes or less to replace from start to finish.

Hi, sorry fixya site is having some problems the experts are not recieving the emails with your response so we have to do it the long way and it takes ages going through all the posts we have helped on.
Ok then if the display is faint then the chances are its going to be the lcd display thats the problem as the display is working its just not lit up so replacing this will solve your problem but its not an easy job to do and is extremely dangerous microwaves are one of the riskiest things to work on as they give of radiation so breaking any seals can cause damage to anyone standing next to the microwavy.
The display is usually lit up showing the numbers but as you can see them faintly this tells us the circuit is okay and not shorting so its not anything drastic but replacing would be difficult.
If the inside is fine where the runners are then the chances are it would be worth getting repaired but if the paint has worn away or any rust is visible then the safest option is to replace it ok. Let me know if you need further assistance ok
This is a common failure of the control panel assemblies of these and similar microwaves.
We repair these control panbel assemblies nationwide for only $32.50.
