Purchased a used flat screen, tv makes a electric noise

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Switch off with X-RAY error message

That is unusual. The only time a TV screen will stand a chance of emmiting small amounts of X rays is when the EHT exceeds, for a 29" tube, 32KV. The tube normally runs at around 27KV
I would get it checked out and have the EHT measure with an electrostatic meter.

Please, be so kind to send me electric schema ( wiring diagrams ) for washing machine bosch V447 CV 5400 Constructa 2HK

Hi from retired Englishman in SW France,

Sorry but this forum does not supply manuals or schematic diagrams direct; it's just made up of ordinary guys and gals, probably at home, with often huge amounts of experience of addressing peoples problems with their machines;-0)

I suspect that even if you contacted the manufacturer (on-line) it might not provide you with one- they are usually reserved for the service engineers rather than we public but good luck anyway!

Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from, Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

We had apower surge while watching tv. now there is no picture, but we can hear the program.

This could be the tuner damaged or a regulator damaged depending where the surge entered the set. Lighting will damage tuners while line power surges will damage regulaters and often horizontal output transistors along with sweep mode power supplies. Since you have audio I would suspect the horizontal output transistor first and check it from collector to base and emmiter for short with a digital volt ohm diode check meter. Check with diode check mode.

I turn the power on and it tries to come on three times in a row and then shuts off

Having in mind that a generic lamp will give you 4500 to 6500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours and that you TV is 4 years old more likely you are looking to replace you lamp;The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
You can check DM;
RCAs are known for bad color wheels and power supplies, which power your ballast, which powers your lamp,
If you can hear your TV fan working is NOT you power supply,but if you hear a constant clicking you ballast needs to be replace,
A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. It supplies the initial electricity to the bulb that creates light, and then it regulates the amount of electricity flowing through the bulb so that it emits the right amount of light.

I hope this will help,please keep us posted.
