Hi,

First,

Turn it off completley and remove the plug from the socket. Leave it for 30 minutes see if you can turn it back on. Bang on the top of it if its goin fuzzy.
There are several possible causes for this type of problem. The most common is some loss of functionality in the horizontal deflection system. What may be happening is the horizontal output amplifier and flyback transformer combination (which generates the high voltage for the picture tube) draws too much current and triggers the power protection circuit to shut down the power ON relay. When it goes OFF, the circuit resets itself over time and if it finds the set to be working again normally, it turns the relay back ON by itself.

The distorted picture when it turns back on is caused by the degaussing coil which was left in its ON mode when the set went off the first time. When the power comes back ON in the set, the degaussing coil makes the picture blurr until the current build up is sufficient that it turns off; then the picture clears up.

My recommendation is:

ONE: Live with it for now or until it fails more completely.

TWO: Contact with a Toshiba factory authorized repair facility only. You should not take it to a general purpose tv shop; they may not be able to properly diagnose it and may not be able to get parts for it on a timely basis. This is NOT an ordinary problem and will require an experienced expert to do the analysis on it.

THREE: There is no harm using the the set this way. When it fails, it will most likely not come on with application of power and you will only hear a relay clicking; then you will have to get it fixed.
Thank You for contacting Fixya

That is only a little problem only electrolytic capacitor is popped up maybe that capacitor range to 470uf 200volts .Just replaced the electrolytic capacitor 10 or 20uf 400volts to become your unit autovolts no problems whatever voltages you input 110volts or 220 volts.Also replaced the fuse maybe its 3 ampere with desame rating .If still not working check the diode maybe it is shorted already.If ever you dont have little knowledge how to solder parts and check the parts for good or bad .Its better you bring your unit to a fined TV repair shop maybe its cost you$ 50 to $60 ,this is only little repair in power supply.

Hope it may helps you:

We just got a Wansa TV but it has a 220V plug. Will tv convert itself to 120 if we use a regular power plug


If there is no indication in the user manual or any spec listing it may not. Most of the time the power supplies used are for the full range of voltages available. It will not damage it to try. Get a power adapter instead of chopping the wire and putting on a new plug. If this does not work, buy a step up transformer 120VAC to 220VAC. Make sure the transformer is rated to at least 30% or greater for the wattage specs. If not the transformer can run too hot.

I love my iron ! How I can use in Israel?


The voltage in Israel is 220 volts. Check the information plate on your iron to see if it will operate on 220 volts. If it will, then you will only need an adapter from the two round pins to a two slot receptacle that you can plug your iron into. If your iron will not use 220 volts then you will need a 220/120 volt transformer with a 1 and one half times larger wattage rating on it than watt rating on your iron. Our iron is 1200 watts. We would need a 2000 watt transformer. On Amazon they cost eighty nine dollars and weigh 29 pounds. And they ship them overseas. Best of Luck

I live overseas, and brought this sewing machine


its not transformer or machine problem at all.all the connections are also proper.its the power issue the required power to the machine is not getting from the electric outlet.just call the local electrician and check out the power supply voltage from the electric outlet.and power required to the machine which will be listed on the machine.if more power is required he will connect the over power IC and get the machine work.if less power is required he will connect the RESISTOR and lower the power to the machine and make it work.

TV won't go on after surge


Don't think you'll find a reset button. The surge has probably taken out the transformer inside the TV.

End of.

Can I use the battery charger BC-400 overseas?


No, you cannot. This is due, not only to the shape of the plug, but also to the fact that the AC cable for BC-400 do not comply with overseas regulations. Though the label on BC-400 indicates the voltage rating (100-240V), the durability of the power cord for each type of BC-400 differs respectively. Minolta has no responsibility for any damage or loss incurred by use of AC adapter or BC-400 not warranted in the region. The mentioned electric cords may not be inseted to the power receptacle. In this case please obtain the transform adaptor at the local dealers. (Please be noted that especially in China there are 5 or 6 types of plug .) Warning: Please be careful when pulling in/out the cord from the power receptacle for the electric shock prevention.

Overseas Use


The operating voltage of the AC Adapter Kit/Compact Power Adapter/Battery Charger is 100V - 240V and conforms with international standards. Voltage may be unstable in some countries/regions. Please take care when using the device. The shape of the plug varies depending on the country/region. Make sure the conversion plug adapter is the right shape for your location.

If this is true, then why does the manual for my new PowerShot SD1100 IS say, "Do not connect compact power adapters or battery chargers to devices such as electrical transformers for foreign travel because it may lead to malfunctions, excessive heat generation, fire, electric shock or injury."

Is this just a standard disclaimer in case something weird happens by using a transformer to charge the battery?

Overseas Use


Yes. The power supplies and battery chargers supplied with all Powershot Digital Cameras are designed to work on input voltages from 100-240 volts (50/60 Hz). The only item that you may need is a plug adapter that allows you to plug the U.S. type power supply or battery charger into the foreign type wall outlet. Plug adapters should be easily available at a local electronics store.
