VCR won't turn on after brownout

We experienced a brownout last week, during which we hurried around the house and unplugged everything sensitive.

Afterward, everything came back up fine except for a Panasonic PV- D4744S DVD/VCR combo. It refuses to turn on. I opened up the case to see if there was any obvious damage, but everything looks fine, even the 125V/3A fuse appears intact. Anyone have any ideas what I can do besides replacing the unit? It's only a couple of years old, it wasn't terribly expensive but it's a shame to have to throw it out already.

Thanks Ken

Have you ever fixed a switch mode power supply? Have you every fixed any electronic component or device?

Ken: "everything looks fine" ..... bad parts don't always burn up and look bad... they need to be tested and replaced by a tech who has the correct test equipment and know how to troubleshoot... The symptoms you reported are common, especially after power outages and storms... and either are easy and economical to repair or sometimes not worth fixing but the only way to know is to take it to a repair shop.... my shop does these types of repairs all the time and in about 8 out of 10 times the repair is economically feasible. So, don't toss it until a tech looks at it... since knowledge, time and parts are not free there may be a charge for an estimate without a follow-up repair... or if you have it repaired, any diagnostic deposit you may be charged would apply to the repair invoice. Check with the local repair shops in your area. Daniel Sofie Electronics Supply & Repair

Thanks for the advice Daniel.

if you know what you're doing, change the low volt capacitors in the power supply as these are the probable cause of what you describe - very common.

Common when the unit is exposed to a brownout?

I'd go check that zener diode in the power supply that always shorts and the IC protector attached to it

Pull the power cord and leave it off for 24 hours. That won't cost anything and sometimes works.

If you have a multimeter, soldering iron, and the inclination to learn a few things you can probably fix this, but you'll have to get in and take some measurements. Bad parts usually look just fine.
