Question about Panasonic SA-HE100 Receiver

Dead SA-HE 100

Lightning struck, taking out the receiver, the com adapter in the pc and a phone transformer. I've found 5 fuses on the p/s board, all check ok. I see no sign of a breaker anywhere. No obvious damage or odor. Any ideas?

    I'm a retired NCR field tech, familiar with schematics and component level troubleshooting, whatever that's worth. A schematic would be most helpful. Anyway, there's no life in the unit. No fan, power cord ok, components show no sign of heat damage, no voltage at transformer. Male AC receptacle (where power cord plugs in)in back of cabinet is a small black box, possibly a fuse(?) Where can I get a schematic?
    Thanks

Most likely if all fuses are good and everything checks out, the something is blown on the circuit board.
In the future it would be best to use a GFCI outlet and a protective power strip, because a power strip for lightning strikes is not fast enough, but the GFCI outlet is and the combination will save sensitive electronics.
I would recommend finding a service man on the website to fix it.

Hi due to it being lightnig strike their could be that much wrong with it that you might never find the problem.
If you are going to try and repair it then your going to need a multimeter and also get hold of the schematics so you can follow them and for any part numbers you might need.
The chances are its going to be several blown resistors because the lightning strike causing power surge so i would start looking around the board where the power lead goes into the board this would be a good place to start testing

    You will need to check any resistors and but the problem could be that it has took out most of the board and you could end up replacing most of the circuitry parts you will need to go through more or less everything but the schematics will help you as following this would give you good idea what it might blow and in what order you can usually get these online in pdf format but getting this would also give you a list of all the part numbers that you might need

    So you have checked power is going through power cord this would rule out the plug socket not working if then you have no power to transformer then it must be between the power cord and the transformer the only component you will have between these to point is a fuse it should have on try using a search engine like ask.com
    and type in
    Schematics for then give make and model
    You should find a few sites that have the schematics in pdf format to download if you have trouble locating one let me know and i can look for you ok speak soon

Denon receiver just struck by lightning.


Any time a unit is hit by lightning, it is usually a total loss. While the initial problem may be fixable, other components have been stressed and are likely to fail. Most shops won't work on these units because of the likelyhood of continual failures. Warranties won't be given or the repairs. In your specific case, the switching IC has been damaged and needs to be replaced as well as the surround processing section. This is best handled as an insurance claim for replacement.

Initial entry:

There could be a number of reasons for this. It woyld help if you could indicate what resistors you changed. The circuit designation should be marked on the PC board. Please post those here and I'll look further and provide some possible solutions.

Unit won't power up completely


The clicks you hear are the relay that completes the circuit for 110V AC to the main power transformer. Mine had the same problem and here's how I've gotten it to work. A lightning strike near our house caused it to fail, and I traced it to the power transformer relay activation circuit. The tuner and amp were fine. I found a bad transistor in the relay circuit, but didn't have a replacement on hand, so I soldered a jumper wire across the relay switch connections on the power transformer circuit board. This connects the 110V AC directly to the power transformer. DC Power to the amp and tuner circuits will still be controlled by the power switch, but the transformer will be supplying all the AC voltages to the main board. If there is a real problem with the circuits that load the transformer or the transformer itself, then the fuse will blow. If the fuse doesn't blow then I suspect the problem is just in the power sequencing circuit itself, that is not needed for operation other than to make the unit "Energy Star Compliant". A lot of electronic items have a transformer that is not switched, and only fused, so that the supplies are available at all times.
