Haier P46C3A A1Vertical stripes appear on the plasma TV screen

The image is displayed from a horizontal screen to a vertical screen, and home computers do not have this function for the time being.

There are four common types of liquid crystal displays:

1.(Twisted Nematic-LCD);

TN-LCD, Super Twisted Nematic LCD);

Layer STN-LCD, double-layer super-twisted nematic LCD);

Film Transistor-LCD).

Liquid crystal display (LCD) is a liquid crystal display (LCD) that uses a substance between a solid state and a liquid state, an organic compound with a regular molecular arrangement, which is heated to present a transparent liquid state, and a cloudy solid state of crystalline particles after cooling.

First of all, thank you, Pheasant King moderator, the information you gave is very good. But there is a part of it that allows me to make an accurate judgment, and during the test, the voltage is mostly normal, and I can't make a judgment on the voltage. But according to common sense, it is the information you gave that the few boards that are not mentioned, in the case of working for 1 hour, only the motherboard cpt this board BGA soldering part has no temperature at all.

But the small capacitor on the back has a supply voltage... Ask the moderators to help give advice and judge. View the original post

Reasons for horizontal streaks on TV screens:

1. The signal of the TV is interfered with and causes horizontal streaks, such as the use of high-power electrical appliances to cause voltage instability; Just find out the source of the interference and rule it out.

3. If it is determined that it is not a signal source or program source problem, it may be caused by the failure of the TV hardware, mainly due to the failure of the screen cable or poor contact, the failure of the display screen, the failure of the internal circuit, etc., which needs to be repaired by contacting the after-sales service of the TV to solve it.

Hello, thank you for asking the company.

Based on the phenomenon you described, first analyze whether the input signal is normal. If it is normal, it is possible that the TV screen is malfunctioning.

You are welcome to ask the company questions again.

We wish you a happy work life

If yours is an LCD, it is possible that the screen is broken. If it is a picture tube, the field part is broken, and it may be caused by signal interference.

It's a problem with the TV, and it's usually the voltage boost capacitor of the field output circuit that's broken.

The 35V47UF boost capacitor in the field output circuit is broken.

You don't have a ** explanation, I don't know if it's a signal, how about changing the channel? Does it still exist? If you watch no matter what program you watch, there are two possibilities for a few fixed stripes, one is that there is a problem with the screen, and the other may be that the screen line is in poor contact or there is a problem

If there is a problem with the screen,If you don't want to do it, you can only change the screen,If it's a problem with the screen line, reinstallation may solve the problem,Can't solve the problem of changing a screen line,About ten yuan

It should be that the temperature difference at home is large. If it's still under warranty, you can repair it. (will give you a small part, but it doesn't work).

Then go to Haier after-sales, and the quality problem of just buying this should be able to be replaced.

Your 100% screen problem is not easy to deal with!! But it's not that there is no way to deal with it, repair the screen, there is such a repair in a larger city!! You can pay attention to "Yiyi Home Appliances", call their official **, and someone will assist you in dealing with it, without charge.
