Options. No Picture. Backlight and Sound Work. Hisence 65U6G. I have ordered all of the boards in a kit from shopjimmy however while swapping left and right T-Con output cables I noticed one had a burned trace. I flipped the cable end for end and it burned another trace on the same connector PIN number. I have now also ordered new 60 pin cables.
It may be a faulty antenna cable connection, at either end that is degrading the strength or quality of the signal making any interference more evident. If a "box": How is it connected to the TV, HDMI, Component video, Composite video, etc? Have you tried different inputs, input types, signal sources e.g. a dvd player, to check the display is ...
Hisense 58H6550E red light on with black screen. I have a Hisense 58H6550E smart TV, and about a week ago the screen went black. Originally, when I unplugged it and plugged it back in, the red light would come on, and once I pressed the power button the red light would turn off and stay off. If I pressed the power button again it would remain ...
Mise à jour (23/05/2020) xFlPr0z that is a broken LCD screen. You will have to either try to source a replacement or you can try and sell the boards from it to recover some of the cost of replacing the TV. Remove the back cover and you should find a label that will tell you what make and model your panel is. Do an online search and see if you ...
Since you have the TV dis-assembled, consider getting a backlight tester (supplier example only) and connecting it to the disconnected LED power cable, (assuming it is connected to the power board) to test the backlights, independent of the TV being powered on. If all the backlights turn on, then it’s looking like a mainboard problem.
The first Hisense television was model CJD18, produced in 1978. Then in 2013, Hisense invented a type of transparent television. And in 2020, it introduced the world’s first true 8K 10 bit HDR screen TV based on an AI-powered HDR algorithm and an image quality engine claiming 6.5T supercomputing power.
TV speakers – Always output audio to the built-in TV speakers. Optical – Always output audio to the S/PDIF optical port. Turn off the built-in TV speakers. Regardless of which setting you choose, your TV automatically mutes the active audio output when you do any of the following: Plug headphones into the headphone jack on the TV.
First make sure that the power board supplies proper voltages to the main board. Then check the LED connector and see what the voltages are on it. If you have no power to the LED connectors it is your main board not enabling the backlight. If you have power to the LED connector but no backlight, it’s your Backlight LED arrays.
I have Sony Bravia LED 3D TV KDL 43W950D. Sl no. 8526842. Few days before i,e. on 15/12/2020 in the morning when I was started my tv it was displayed white screen then blinking red 5 times and so on. I have informed to Sony Service station then service engineer came to me on18/12/2020 and open the back cover and clean the dust then tv was o.k.
Once I turn the TV on: 1) Backlight Enable line between power supply and main logic board - always 3.7V (driver IC datasheet says it needs 1.7V for enable or higher and below 0.8V to disable) 2) Backlight dimming signal is 98% Duty cycle 4.7V (according to driver IC datasheet, should work). So pretty much stable 4.7V there.
