The TV has to be played for half an hour to be clear, and there is still one side that is not displa

The problem of unclear should be that the CRT tube socket is damp, resulting in the abnormal focusing voltage of the CRT and cannot be focused normally, and the heat of the machine will drive away the water vapor after working for a period of time, so the display is normal again.

As for one side where there is no image, check the line scan circuit.

From these phenomena, it is not possible to determine the aging of the picture tube, at least if there is no image on the right side, it is impossible to cause the problem of the picture tube.

It's not good to repair it basically,Because the screen is the essence of TV,I bought it at the beginning of the year and half of the screen is black during the warranty period,It's very troublesome to repair it and replace it directly with a new machine,Make up 300 yuan to the store。

Hello, the picture tube of the TV is aged, like an old man in his nineties! Buy a new one, the current LCD TV is also very cheap, the 34-inch TV is only more than a thousand, not expensive at all! Wish.

And that's what I'm looking at, it's probably the display screen, the image delivery part of the TV.

In the case of LCD TVs, it is the problem of the driver board, and in the case of old-fashioned color TVs, it is the problem of the tube base.

This is damp, and you need to change the small pipe fittings inside.

It is recommended that you find a specialized repairman to take a look.

Your TV is broken, or it's damp

When wet, magnetic, or has a problem with the display.

There is a possibility that the CRT may be defective or deteriorated.

Is your monitor half or middle, and is the image complete?

If yes, it should be that you adjusted the display mode of the monitor to only display the 4:3 screen, look at the manual, and adjust it back!

If the image display is incomplete, it may be that the signal board is broken, and the most serious thing is that the screen is broken! Or send it directly to the after-sales service!

Only the right half is shown, and the left screen is black.

The phenomenon that the TV appears half white and half clear,It means that the TV backlight board is operating normally,You should first judge whether the motherboard is working normally,You can press the power switch,Check whether the indicator light is reflected,If the indicator light is on,And change the color,It means that the motherboard is working normally。 Check whether the connection cable of the motherboard signal output to the screen is in poor contact (the connection cable or screen can be replaced) Check whether the voltage of each working point of the motherboard is normal, especially the oscilloscope for the power supply voltage of the screen.

Check the line signal and clock. The specific situation of the TV with half a white screen and half a clear screen:1、Check the fault of the machine first,Logic board。

Whether the upper screen cable is in poor contact or damaged, etc. 2. If the above checks are normal, then measure whether the voltage of the circuit supply is normal. 3. After the above measurement, the power supply of the logic board circuit is normal, then the next measurement is to measure whether the voltage of all DC-DC voltage conversion circuit chips on the logic board is normal for the pins of each output terminal, and if there is any abnormality, check the components around the abnormal pins of the chip.

4. If the above measurement chip is abnormal, the components around the feet are normal, the fault may be that the main control chip on the logic board is abnormal or damaged. Otherwise, this problem is likely to be damaged by the LCD screen, so about the above faults, it is recommended to be careful and serious, with a multimeter.

Measurement in order to accurately judge the fault location.

Hello,Dear,LCD TV only has half of the picture,It may be the mu of Shen Oak caused by poor contact of the screen cable,It is recommended to disassemble the machine,Then pull out the plug of the screen cable,Wipe the metal sheet with cotton dipped in alcohol,Then reinsert the cable to connect the side port,Fix it to return to normal; It may also be that the logic board is broken, and it is recommended to ask a professional maintenance personnel to come to the door to check the filial piety banquet repair.
