Why is our Hisense tv turning off and on by it self it also is on blue screen and stuck on channel 51-2
Fault at its main digital board. Short circuited component/s at it
. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

My Hisense 50K23DG T.V. wont turn on?
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.

Where is the Hisense 50K23DG Backlight Inverter located?
Hi, The part number for this inverter is: 167210, RSAG7.820.5463,it will be printed on the board somewhere perhaps on a sticky label, have a good search around all the boards if you are unfamiliar with the set. If its any help start with the smaller Boards first, the largest will be Main AV and the Power Supply

No power is getting to the board at all. it appears to have no fuse, where the fuse should be is a little brown cylinder shaped object T4A 250v it is soldered to the board. is this my problem?
Your certainly doing all the right things. I wish more people on this site would give a great description like yours.
OK, so Process of Elimination.
An AC Multimeter would prove useful here.
Assuming your fairly technical and are aware of electric shocks.
Use the meter on AC scale to check for 110 or 240v AC inside your TV power supply section.
Does it get to the board? Does it get to the Switch Mode Power Supply?
Switch Mode power Supplies can be powered up by a normal AC type switch (ac wires to physical switch) or a Logic type switch. (Like on a computer Keyboard) This triggers the Switch Mode to turn on. Usually you get a high frequency zip sound.
Is the switch mode supply open on the PCB or is it in a Metal Enclosure? (perhaps has a separate fuse inside) the Electrolytic capacitors inside here are in a harsh environment so this is where they leak or bulge.
If the Switch Mode Supply doesn't come to life then you have the problem.
The other side of the Switch Mode Supply is lower DC voltages. Perhaps 12v or 5v. Use the multimeter to check.
A logic type switch usually stores a voltage in a capacitor on the secondary low voltage side of the Power Sup. When the logic switch discharges the cap it fires up the SM Power Supply. This is how computers boot up. So look for bad cams on low voltage side.
See where wires come in from switch to Power Supply.

Hisense 55R6E no picture /no sound
This model set had defective LED lamps from the factory and only lasted 1000 plus hrs...You can get lamps that will last from shopjimmy that will fix the issue for about $60 with shipping. Its not a hard job changing them, just takes some patience and care when handling the screen as it's extremely fragile on most lower price sets.

Hisense LED LCD TV, Model 50H5C NO Video No Sound
Your LED backlights are bad and need replacing, it's something you can do yourself but look at some youtube vids before attempting to do it, the panel is extremely fragile on this model set, be careful handling it or it will break then the TV is junk and the money spent on lamp strips is waisted. Also match the old strips to the pictures of new ones as this model uses 2 styles of strips, best place to buy them is shopjimmy.com

50k23dg Blue Screen with Vertical White Lines
The main board and the power supply is bad for your TV and it would be more easier to buy a new TV than to try and fix the current TV that you have and that our TV could of had died on you.
