Question about Hisense Televison & Video
I see so many here with no sound/nopicture issues:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.
Answers to issues:
1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.
2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.
Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.
What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.
3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.
4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.
If any or all of this information is beyond you then consider the set is in shutdown as something is wrong===likely in the power supply of the set which is where most of these problems happen.

SOURCE: red blinking light
The red light blibking 6 times indicates that the power supply board has a defective or damaged area. I know this because i had the same problem...bought a damaged tv for parts and replaced the power supply board as the tv would not turn on...wokrs like a charm now.

There was a firmware update from Sony for power up & down problems for the KDFE42A10 among other models which were made in July 2005. If you go to the Sony website (service/support) you can find a link where you can enter your model # and serial # to see if your TV is affected.
The update takes an authorized service guy to come to you home and load the new firmware from a USB memory stick. It takes approx 5 minutes to do. Mine has worked flawlessly for three years now and it was Sony who contacted me to do the update within the first few months I owned the TV.
You should have this done if your TV is affected. Sony indicated that power on and power off problems could begin after six months or so if the update is not done. Sounds like it may be the same issue unless your lamp is bad.
Also, if you have recently had the lamp door open for any reason, you need to ensure it is closed and locked correctly or the lamp light will flash three times in red and won't allow the TV to start up.
This is all covered in the manual under the Troubleshooting' section and is also referred to in the first few pages of the manual where the LED are explained.
Good luck !

Try leaving it unplugged for an hour so it can reset itself.
If it still has the problem, it may need a new power supply inverter board. That's what happen to mine.

The unit has a fault on its power board and sustain board.
It turns off because the sensor is preventing some component from bacoming overheated and catching fire or damaging further components. Seel professional repair.
