Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: My Hisense 50H5G LED TV has sound but no picture. I did the flashlight test and saw an image. Does this mean the Tcon board is bad?

No it means you have no picture, you must do the testing to decide if the PCB is defective or not.

SOURCE: Hisense 50h5g model the backlights are blinking the pictures is really dark but sound quality is still good what may be the issue

First I want to say I do not have the best writing skills so please look past the lack of punctuation and possible spelling errors with that said I'll give my answer .

I have seen and repaired this problem manny times in manny different brands of tvs including most if not all the so called reputable brands, and I don't recall it ever being any of the boards as mentioned in the answers above. For tv's that use led 's for the back lights I have found that the back lights will fail to turn on at all or flash on once briefly when the Set is powered on. I have found most cases this is caused by a single led that has burnt on one of the led strips inside the TV . The led backlighting basically works the same as Christmas lights do any time a single light burns out the whole stran goes out and you have to find and replace the bad light to fix the issue you can replace a single led but it requires some advanced soldering skills . You can order a new led strip and replace the bad strip locating the bad strip you need a digital volt meeter and look up how to test led with a volt meeter . I hope this answer will help others that experience this problem

Should have worked after the hard reset. Your problem could be with the leds or the inverter board. Do the flashlight test.

If the back light is CCFl type; check and replace all CCFL lamps and back light inverter board.

Hisense 50H5G tv screen is black. It has no backlights either. It does have sound. Is it the t conn board.


I'd be willing to bet it's a connection on the board if the sound is working. usually, just open up the back and look for the ribbon connector running from the screen to the board. check and make sure it's fitted good. maybe even disconnect and reconnect just to be sure. then give it a go. if not, the screen itself or something on the board may be at fault. hope this helps

Bad LED on Hisense 50H5G, no picture or sound, but the Hisense can be seen with flashlight.


Hi,
Hisense can be unbelievably expensive on parts, consider a salvaged part with a warranty from shop jimmy or similar, much cheaper than the manufacturer but you will have to fit the panel or find a capable friend

Where do I find the manufacture's firmware file for a Hisense 50" LCD smart tv model 50H5G


You have the link to the official website of Hisense. So not sure why you had a problem. I am assuming you purchased the TV in USA.

If that is not the case then you may have to go to the Hisense support website in your country. The firmware can make a difference to the local TV type e.g, PAL or NTSC.

If you are in USA then try once again. Type the model of your TV in the field and download the firmware zip file and install as in instructions provided. Hisense Firmware

You can change country by going down the page at the bottom of the Hisense USA site. It is possible no firmware update was available for your country. This means you have to call local Hisense support and restore the original firmware file.
