              Hope 2022 brings Budm good things. Anyone that gives a company 25 years of the best of their lives, only to be laid off, is just plain criminal. Thanks Budm for everything.

                  You should at least plug the unit you are working on into the GFCI outlet for safety.

                                    85” Hisense TV

                                    Greetings,

                                    Request for Technical Assessment – Faulty Hisense 85Q6NAU TV

                                    Dear TV technicians of forum, I hope this message finds you well.

                                    I am writing to seek assistance regarding my 85-inch Hisense Smart TV, model 85Q6NAU, which is currently experiencing a fault. The unit is approximately two years old, and I am not sure if it has a warranty.

                                    I have attached a photo showing the issue for your reference. I would appreciate it if your experienced technician could kindly review the image and provide some insight into the likely cause of the problem.

                                    Could you please advise:

                                    · Whether the issue appears to be related to the display panel or possibly the main board or T-CON board?

                                    · If a display panel replacement is required, what would be the approximate cost of the panel?

                                    · Given the size and weight of the TV, it is quite difficult to bring it into the service centre. Is there any way to assess or repair the unit without transporting it?

                                    · Based on your experience, would replacing the display panel be a cost-effective solution, or would you advise against it?

                                    Your professional opinion and guidance would be greatly appreciated.

                                    Thank you in advance for your time and assistance. I look forward to your response.

                                    Warm regards,

                                    Barry M

                                        Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                                        Hello Badcaps Community,

                                        I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

                                        The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...

                                        Good evening, gentlemen.

                                        I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

                                        To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

                                        by momaka
                                        Looking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.

                                        I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.

                                        When I saw the Craigslist post, I wasn't...

                                        4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                                        Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                                        Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.
