My hisense 55 tv screen goes black after a few minutes with no sound. What could be the problem? It turns on again with a picture, but after 5 minutes, same thing happens.


The main power supply regulator section circuit fault. 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.

Lcd Hisense TV powers up with blue light,but no picture and sound.


Main board is probably bad or the power board is not powering the main board. Common problem with Hisense tvs and their customer service is lacking if under warranty. My hisense chromebook has been dead for almost 2 months...still waiting on a return authorization for warranty repair.

What makes the HISENSE LCD (Model LCD 42W58P1) power supply failed to produce output voltage goes to the main pc board?


Hi,
First of all the power supply makes 'Stand By 5 or 3.5V which goes to main board. When we give power on command to the TV the main board sends 'stand by or Power ON' command to the power board which then makes other necessary voltage for the main board as well as other sections. If the power board does not receive 'Power On' command from main board, it will not produce the necessary voltages to operate the TV set.

My hisense 50 inch lcd tv has picture but no sound.


If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel

The color on my tv has gone crazy. There's either a blue tinge or a yellow tinge when I adjust the colour (so either people look like they are faintly related to a smurf or have scurvy!!). I am also...


I would suggest to unplug the TV from the AC power outlet first, wait a couple of minutes to plug it back in. If that does not work, the main board is defective since is not providing proper video info to the main digital controller board (D board). The Main board part number is: TNPH0721AJS or TNPH0721ADS. If you need to verify the main board part number, you will need to remove the back cover of your plasma to check it out.
Let me know if you require further assistance.
