The best advice you can and will get is to replace the backlights, these need to be replaced as a set not just the individual strip thats open. In this set there will be 3 sets of backlights, each set wired in series, like Christmas tree lamps, if you take one bulb out the entire string quits lighting. So your saying ok I have one bad bulb making that set not work but why don't the other 2 light, the reason is, the backlight inverter is a part of the power board, it has shut down capabilities for safety reasons, the voltage on the set with the open lamps is going to be higher than it should be, the PWM circuit shuts down the entire backlight voltage, not just the string that's open but all of them, it's how most lower end sets work, now on higher end sets such as Samsung, LG, Vizio ect you can have one strip or set bad and the rest will still work. Hope this sheds some light on what's making all the lamps not light.
How old is it? They are not the best sets even when new and they certainly aren't made to last. It sounds like the Power Board has failed. Did you try a Power Reset? Remove the mains plug for 15 minutes, press and hold the On button for 12 seconds as you plug it back in.
Hisense TV forgot password
The easiest first step to unlock your HISENSE H65U7A password is to call back, or send a message to the former owner. However, he or she may have forgotten it! In that case, do not get upset. The default codes are 0000, 1234, 1111, 7777 or 9999.May 23, 2018
it's not possible to confirm the capability of the Hisense 22 inch HSL5529HDI TV to support a 15Hz RGBs signal through its VGA port without access to its specifications.
However, most consumer-grade TV sets are designed to work with modern computer and video signals, which typically have a refresh rate of 60Hz or higher. They may not support lower refresh rates like 15Hz, which is a relatively old standard.
I would recommend checking the specifications of the TV or contacting Hisense directly for more information on the TV's capabilities and compatibility with older systems and their RGB signals.
A blinking red light on the power button of a Hisense 55 inch model 50R6E3 TV could indicate a problem with the TV's power supply. It could be caused by a malfunctioning component, such as a blown fuse or failed capacitor, or it could be an indication that the TV is overheating. In some cases, a blinking red light can also indicate that the TV's firmware is not up to date and needs to be updated
First thing to do is put the original boards back in the TV, none are bad, you have defective LED strips in the panel, real common issue with this model set, the power supply inverter senses the over current and shuts down, you get the blinking standy light when this happens
If your Hisense 55-inch 4K TV with Android is turning off randomly, and you have found that the power supply board is wet, it is likely that the issue is caused by a problem with the power supply. Replacing the power supply board may resolve the problem, but it's important to consider the following before making a decision:Safety: If the power supply board is wet, there is a risk of electrical shock, so it is important to make sure that the TV is unplugged and that you take appropriate safety precautions before handling the power supply board.Root cause: The problem could be due to a leak or another issue that caused water damage to the power supply board. If the root cause of the water damage is not addressed, the new power supply board may also be damaged.Difficulty: Replacing the power supply board can be a difficult task, and it requires some technical knowledge and the right tools. It's important to make sure that you are comfortable with the task and that you have the necessary tools before attempting to replace the power supply board.Cost: replacing the power supply board may not be a cheap solution, and it may be more cost-effective to consider a new TV.It's important to have a professional technician to check the TV and confirm if the power supply board is the issue and if it needs to be replaced.If you're not comfortable with the task of replacing the power supply board, it's best to contact Hisense support for further assistance or have a professional technician to check the TV.
If your TV has a digital tuner, you can get any HD channels if you use the correct antenna pointed at the transmitter and are close enough to the transmitters. (Antennas labeled as HD are not always appropriate for your location.) Your TV will downgrade the signal to 480i if the TV can't support a 720p or 1080i resolution.First where do you live? Use antennaweb.org or tvfool.com to determine the correct placement of your antenna for your area/stations. AntennaWeb uses a very conservative signal strength calculation despite assuming an external antenna. Tvfool will give the antenna color rating which is also provided on the antenna package. When properly installed (with no trees or hills blocking the signal), the matching antenna should receive the listed channel.If you use a splitter to share the signal with several TVs, you may need an amplifier to bring the signal strength to that needed for the tuner to interpret the digital signal. (Note: amplifiers and splitters can fail and the amplifier may become a signal filter blocking the signal; test the antenna strength on a direct connection if there is a problem.) If you do not have a digital tuner in the TV, you may have gotten an SD digital to analog converter. These are the more common (and available with the government coupon) converters. You will need to get an HD capable tuner to see the full HD signal. Please add a comment with your TV model and antenna choice for additional support. Cindy Wells (antennaweb indicates that my external antenna should only get the stations 10 miles away. We actually receive the channels from 30 miles away. We use an amplifier splitter to feed the signal to several TVs. I set up two indoor antennas for a neighbor's TVs. One gets the signals from the transmitters 30 miles away and the other from the transmitter 10 miles away. Both get HD from the stations with HD broadcast (not all channels are in HD here). The difference is totally due to antenna placement.)
There are several potential causes for a Hisense 55 TV to go black and start flashing the start-up screen almost imperceptibly. Some possible causes could include:
A problem with the TV's power supply: The TV's power supply unit could be experiencing a malfunction or failure, causing the TV to shut off and display the start-up screen.
A problem with the TV's HDMI or other video input: If the TV is connected to a device such as a cable box or streaming device via HDMI or another video input, there could be an issue with that connection that is causing the TV to display the start-up screen.
A problem with the TV's main board: The main board is responsible for controlling the TV's various functions and components. If the main board is malfunctioning, it could cause the TV to display the start-up screen.
To troubleshoot the issue, you can try the following steps:
Check the power cord and outlet to ensure the TV is receiving power.
Disconnect the TV from any devices it is connected to and try turning it on again.
Check the TV's user manual for any troubleshooting tips or reset procedures.
If the issue persists, it is recommended to have the TV inspected by a professional repair technician. They will be able to diagnose the issue and recommend the necessary repairs
Si su televisor Hisense 50 50H6E 222172 tiene una pantalla negra, podr?a ser un problema temporal. Primero intente reiniciar el televisor desenchuf?ndolo y luego manteniendo el bot?n de encendido presionado durante al menos 30 segundos. Esto ayudar? a descargar cualquier energ?a residual en el televisor y permitir? que este se reinicie. Si esto no funciona, verifique todas las conexiones HDMI para asegurarse de que est?n conectadas de manera segura. Si esto tampoco funciona, podr?a ser un problema con los LED de la parte posterior del televisor. En este caso, es posible que tenga que reemplazar los LED para solucionar el problema. Si el problema persiste, comun?quese con el servicio t?cnico de Hisense para obtener ayuda.
