LBP 7200 Burnt out 110V, how to repair if got the same but for 220V

Have a look on ebay for cheap converters:

if you need 110V US to 220V UK (6.99):

or 220V UK to 110V US (3.00)

Hope helps

More than likely you fried the boards and even if to change them out ,you still run the risk of electrical shock. My advice is to send it back to the company for repair or get a new one. Plugging a 110 unit into a 220 line has happened to me too! I still feel pretty stupid I did it, but stuff like this happens and it is good that you were not injured.

You may be lucky enough that the capacitor exploded from the 220 volt charge. You will have to enquire at an appliance repair shop for exact advice. Basically I would junk it and get the correct unit for the voltage and cycles in you area.

If you want to fry your electronics or appliances that's it's a sure way to accomplish that.
While appliance working ONLY at 220v will just not work or under perform (like a hair drier) when plugging electronic equipment that runds ONLY at 110v then that item will be "fried" as all its electric components will be burnt as it will receive twice the power that it was build to receive. Should that happen the safety switch on the 220v circuit where the item was MISTAKENLY plugged will be triggered (hopefully or there will be risk of fire and serious injuries, even death) and the power will be shut off. That's a major but possible mistake.
If traveling abroad those who come to US will unlikely damage their appliances (like electric razors) as they will receive less power (110v vs 220v) and usually these items are protected against these mistakes by the specifications of their own design. The opposite is not true of course as just mentioned above.
So do not play around with dangerous items please! ;) On a positive note though: Nowadays most appliances have dual power and should work whether plugged in a 110v, 60Hz (most common in US) or 220v 50Hz (most common in Europe). So nothing really happens... it just works as long as you have the proper adapters to plug the appliance to the different receptacles.
Note: One of the differences is that (without going into the math of it all), an appliance working at 110v will draw x2 times the power than it draws when working on 220v so if an appliance was drawing 3A at 110v it will only draw 1.5A when working at 220v.
Best.

bad capacitor on the inside of the unit.
usually the 10000uf 16v tall cap blue or black cap.
look for a bulge on the top.
replace it with a higher voltage cap.

Most likely what got burnt is the bridge rectifier in the power supply section of the electronic circuit. This usually takes the shape of either a single 4-legged IC, or a group of 4 rectifying diodes connected in a bridge configuration. If you disassemble the unit to which the power cord is attached & trace the circuit starting from the terminals of the power chord, you can easily identify it. You will need to replace the 4-legged IC or the 4 rectifying diodes.
You will also need to replace the fuse, since it is usually likely that it gets burnt if the unit is attached to 220V instead of 110V.

no heat usually means your only getting110 volts into your dryer.....you need the full 220volts to run heaters....with voltage meter you checkwires on the plug OUTLET...or inside back cover REDwire to WHITEwire =110v.........BLACKwire to WHITEwire =110v.....REDwire to BLACKwire =220v. you probably have aBAD 220V. 30 amp circut breaker..or if still using FUSES one is burnt out (In house electric panel) or burnt off RED or BLACKwire in back of dryer.....

You have damaged the system beyond economical repair. There are so many components inside that have fried that it is impossible to repair. Sorry. That's what happens when you overvolt an electronic circuit.

your adapter burnt out, its better you bougth a new one

The Fuse for these model is 110V - 250V, so definitely the machine will still light up for a moment then black out. So if you accidentally plugged it to 220V (if it is 110V) you have to change the whole PCB. Electric current are distributed by PCB which only handles 110V.

I suggest when you change the PCB try to change also the Fuse to 110V only so that next time if by accident it was plugged to 220V you just have to change the Fuse not the PCB.
