Top 20 Hisense TA42P40M 42 in. Plasma Television - Page 5 Questions & Answers

I've answered several related questions on the Hisense sets with R6E3 as the letters and numbers following the screen size. This series of sets have panel issues, the COF IC's are defective and they aren't replaceable, chances are you will need a new TV

Question edited for clarity. Although I had Sky in the UK before I moved to Canada, I am not conversant with this infra-red device. Scanning on a television is normally reserved for over-air signals via an aerial. Picking up specific device is via HDMI inputs, via Bluetooth or via other devices that are connected to your home WiFi network that the Smart Television can see. I found this and this

In this case and on this brand set it's best to replace all the strips, if you only replace the bad one. or ones the anothers will fail in a few weeks to months so it's back to square one with needing to open the set up and lift the panel and replacing the bad ones again, also it's cheaper to replace them all than one at a time in most cases, you most likely will find several strips that have shorted diodes that will need replacing, it's seldom just one diode that opens up making the picture black. Also when handling the screen use extreme caution, it's VERY fragile and sensitive to static that will damage the panel boards, making the set not work once it's back together. You will get backlights but have what's called the blue screen of *****, then the money was waisted attempting to repair the TV with new lamps. Hope this helps, I apologize for the answer bots on this site that give generic non helpful answers, wish their tech department could do something to stop them but so far it hasn't happened.

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.

If it's Hisense it's most likely backlights that are bad, average life of a Hisense TV is 26 months, needless to say there are betters sets for the money. There are 2 choices with your TV, order backlights from shopjimmy.com and change them yourself for around $100 with shipping or recycle the TV as it will cost around $400 to take it in to a repair shop for service, might as well buy a new TV then. If you decide to repair it yourself you will need suction cups to handle the panel, without you most likely will damage it, another downside to Hisense is the panels are very thin and very fragile

My first thoughts are to recycle the TV and buy another as this model was plagued with problems. But if you want to fix it you will need some voltage measurements, the 5 volt standy is good since you have standy lamp, the 1st voltage reading would be on the power board connector going to the main board, look for a terminal marked ps-on, pwr, pr, or something that starts with a p, turn the set on at the tv or remote and look for 3 vdc there, if you don't see it replace the main, if you do message me back and I'll get you more info on what to test next but I don't you will find this voltage.

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

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.

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:

1. 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.
2. 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.
3. 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:

1. Check the power cord and outlet to ensure the TV is receiving power.
2. Disconnect the TV from any devices it is connected to and try turning it on again.
3. 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

It sounds like a power supply issue, but this is the best advice https://www.fixya.com/support/r29790007-repairing_own_television ..

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

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.
