Something "Fried"

[jhhowell]

Hi All:
It's too lengthy to get into "how it happened", but 220 volts was applied to a recepticle that a 32" JVC TV was plugged in to. The set was not "on", but I now have nothing. Is there a fuse inside the cabinet? Would the over-current blown the on/off switch? How much do you think was destroyed?
Thanks,
Jim

Yes, there should be a fuse inside.
You'll need to check Standby power supply (at least). Everything between the AC Plug and this side of any Manual (Vacation) switch or relay contact.
On-Off switch should be isolated.

As much as I can say without set's model number.

jts1957...Thanks for the reply. Some of the info I provided in the original post was incorrect. The TV is a Zenith, purchased in 1998. Requested Info is as follows:
Model No. A27A23W
Serial No. 821-44430030
I have not opened the set yet, but I did look at an air conditioner that was also damaged and there was a 250V, 3.7A fuse that was blown. Replaced it and it now works fine. The TV and a computer are the only things I want to try to fix. What caused all of the damage was when I had my Mom's house upgraded (100 Amp to 200 Amp service) the electrician didn't check the power arrangement in the detached garage and the way my Pop, God rest his soul, wired the garage, we ended up with 120V applied to the hot buss and 120V also applied to the neutral buss. What do you get other that a lot of "broken" equipment...is 240V at the plug. Hopefully I can get it all working again.
Thanks again,
Jim

jts1957,
I forgot to thank you for your advise. The first place you said to look was the fuse...and that was it. Works like new!
Thanks again,
Jim
