How about Skyworth 42m10hf

You can think of a TV as a computer, except that it saves the URL of opening the network TV to the TV.

You can set it up by connecting the cat directly!

42M10HF is basically delisted, and there is only 42M11HF left in the market at the moment.

In fact, it is the poor capacitance of a patch on the backlight driver board, which is a common problem of the 42TLQ board.

I repaired more is that the backlight driver board is broken, if there is, you can replace the test machine.

Reply to Ximen Xuechun's post is nothing! The owner has taken it to the after-sales service. Pity.

Reply to Wang Yao's post and fix the LCD less! Faux pas! Further training is required. I hope the masters will give more advice.

But the screen 03 is imported by LG's IPS hard screen, and the 05 is now soft and flat, and it is a Taiwanese panel! 05 Watching TV will be fixed in U-03 There is no such problem! Hunan Satellite TV and Zhejiang Satellite TV's advertisements are cool open TV,And 03 series is240hz refresh rate,But 05only60Hz,Different grades of two TVs!

03 Not only ***, but the sound effect is still not wrong, that is, the later launch of M10 and K10 has some better places than 03! It is recommended to choose Kushen Jikai TV to choose the 03 series! Practical and cost-effective!

The downside is that the design department is a good look!

Maybe the spotlight inside is broken.

Let's take a look at whether the plug of the set-top box and the TV is well connected,If the connection is not good, this state will also occur,No problem with the connection is estimated to be the reason for the TV itself,Then it should be after-sales**!

Is the clarity of the signal source high?

1. "This fault may be a problem with the power supply circuit, but it is more likely to be a problem with the backlight drive circuit":

First of all, measure whether the voltages of each group at the output end of the main switching power supply circuit are normal, especially whether the voltage of the 24V group is normal and stable.

When the above voltages are normal, this means that the switching power supply circuit is not faulty, otherwise it is a switching power supply circuit problem.

Even if the above is normal, then this fault has to measure the backlight drive control chip, whether the voltage of each pin to the ground is normal, if there is an abnormality, check the components around the abnormal pins of the chip.

Personally, I feel that Skyworth is better, at least after-sales is more comprehensive than Changhong.
