Question about Hisense Televison & Video

1 Answer

LCD tv Hisense model 50K23DG. No picture, No sound, No backlight. Voltage all look good. When I press power, the red light flashes 6 times. I am suspect its an LED failure.

1. Do you think i have a bad LED? 2. Can i test the LEDs without tearing it apart? 3. Do you suggest testing another possible fault?

Hello Kenpappas, for what you describe, it would seem like a backlighting problem
questions if you can have a bad led ?, if many times a Led, is the one that proboca the failure
The correct solution from my point of view is, replace, all the Leds
As it is not practical to replace each led in the strips
It is more practical and simple, replace the full strips of leds
I send you a video, in which they show, the procedure of replacing the LED strips on a Hisense TV
I hope you can solve the problem
Greetings Franco Dosil

Hola Kenpappas, por lo que describes pareceria problema de retroiluminacion
preguntas si puedes tener un led mal?, si muchas veces un Led, es el que proboca la falla
La solucion correcta desde mi punto de vista es, reemplazar, todos los Leds
Como no es practico reemplazar cada led en las tiras
resulta mas practico y sencillo, reemplazar las tiras completas de leds
Te envio un video, en el cual muestran, el procedimiento de reemplazo de las tiras de Leds en un televisor Hisense
Espero que puedas resolver el problema
Saludos Franco Dosil

SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

SOURCE: If a warning light indicates the CPU is not functioning, does that mean I have to get a new processor?

Yes! judging by all the cascade break downs, I would suggest replacing the motherboard, HP has a history with motherboard issues.

SOURCE: On my Hisense 50K23DG LED TV, I have sound but no picture.

Hi,
Hisense TV's usually use PCB Boards by Vestel and not Hisense themselves, have a look at: Vestel Help If the Boards in your Hisense match this Board/Part Number format at least you'll know what to search for, replacing the power supply will not help unless the process has been incorporated into the power supply and that is not known for certain yet

SOURCE: When testin a power supply or led board on tv do i test dc or ac with multimeter?

Your power supply board is working if you get audio and imgaes.

You test AC only the AC side of the transformer before the Rectifier Diodes. Everything after the Diodes will be in DC.

did you get to see any spec of backlight as shown in

Hisense 50k23dg backlights are off and voltage test from led driver is zero.

Chances are the power supply is fine and you have shorted lamps in the panel

Red light blinks 3 times on hisense lcd tv why no picture but have sound

If it was an open "internal fuse" the error code wouldn't show!!!... bad advice...

I looked in my Hisense service manuals and 3 blinks error code is LED rail shutdown from over voltage or over current, most likely you have some bad lamps in the panel, you can open the panel up and take a 3 volt power source, like 2 AA batteries and test them one at a time, replace the ones that are bad or its easier to replace the entire strip..Good luck

I have a Hisense LCD T.V. model H32V77C. Power indicator is red. When I push the power button, indicator turns blue, then blinks red 3 times and returns to blue, then shuts off.

hi sounds like there's no backlight voltage, check power supply board for any swollen caps, if ok, test the voltage on the white connector from the power board to the inverter board , with a meter should be 24v dc thanks

I have a Hisense 55" model #50K23DG . The screen went out but the sound is perfectly clear. You can only see the image when you put a flashlight up against the screen. What could be the problem?

i assume this is an lcd, not led tv. the flourescent backlighting's inverter unit has gone out. its usually a seperate ic card, so it is repairable, if you can source the part cheap

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.

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
