LG 42LE5510 HDMI Issue Solved/Closed

Question

Hello,

Here is my problem:
My screen is connected to a Freebox player and a computer via HDMI. For the past 10 days, I have not received any signal: "no signal," yet the cables are plugged in and appear in the "source" menu of my screen (HDMI 1 and HDMI 4, which disappear when I unplug my cables, for info).
- I select the correct output each time (done it 100 times)
- I changed my Freebox player with an HDMI cable
- I connected to HDMI 2 and 3, same problem "no signal"
- I thoroughly configured my Freebox and my LG: "no signal"
- When I plug - unplug the cable connected to my computer, it appears - disappears in my screen devices with the traditional sound of a new device connecting to a Windows computer (ta-da!)
- I updated the software version of my LG screen: "no signal"
- I rebooted my screen in factory reset mode: "no signal"
- My Freebox player works via SCART...
In short, I am freaking out and wondering if it’s simply that LG has a very short lifespan, like premature planned obsolescence (bought in May 2011!!!), or at least some of their components (having a full HD TV and watching via SCART is a bit of a letdown).
My questions:
- Do you see another reason or solution?
- Is it normal that all the HDMI connections stop working at the same time?
- How can I maintain the quality of my screen? Can I connect the HDMI output of my Freebox player to my TV's 5 cable input (I don’t know the name, different colors)?

Thank you for your response, (especially if LG replies directly, I doubt I am the first to experience this...)
Have a good evening ;-)

Hello,

I found myself in the same situation with an LG TV 42LE5510, over 6 years old and more than HDMI (x4) not working despite trying multiple cables connected to PC, Freebox, player...

I had seen this solution using the oven at 200°C but wow!! who could say wow great idea, no one!!!

A moment of madness or a last attempt before heading to the dump in addition to Sebpli's successful trial, and yes, I did it!!!! And what can I say,...... well yes it worked for me at least
I'm left speechless, except for shouting it from the rooftops on this forum

My question for those who might have an idea, what happened to my motherboard at 200°C??
A reset related to a hypothetical "programmed" obsolescence!!, as for the soldering, I believe less because the problem was with 4 HDMI outputs and now they all work!!

The only downside is that I melted the plastic Audio IN adapter (RGB/DV), which I luckily don’t use, so the advice is to remove it (the only piece sensitive to heat)

The modification was done today, I felt too strong a urge to share it, I will confirm in the coming weeks

Saved by my oven, when I tell people around me ........

Thanks for the forum and if this solution can be a kick for the manufacturers, then great

Hello chinoispunk,

I also own an LG TV 42LE5510 purchased 5 years ago and for over 6 months, none of the HDMI inputs are working.
I have done a firmware update, tried a ton of manipulations, and nothing works, I get the message "no signal".
I don't have a Freebox, but my problem is somewhat similar to yours.
I also have a lot of questions like you about premature planned obsolescence...

Have you found a solution to your problem? If so, how did you do it?

Thank you very much,
Best regards,
Davide.

Oh that's great, I have the same problem as you with my parents' TV. I'm going to save myself all the hassle since nothing is working... The weird thing is that the sound comes through but not the picture when I switch to RCA mode from my Love Box to the TV.

I'm leaning towards planned obsolescence because my parents have rarely used the HDMI port in recent years until the installation of the live box in December. And the ports stopped working at the beginning of February, so a month after yours... Hahaha, what a coincidence.

Hello everyone, Have you tried calling them, "3220 - Say LG Free call from a landline" They have always been responsive with me  -- I call a spade a spade *      *in French in the text

Hello,

in 2 months, I will buy a new TV. I will test putting the TV card in the oven at 200°C for 10 minutes. See video on YouTube: https://www.youtube.com/watch?v=y6BMVL4VF5c&feature=youtu.be

I will keep you updated if it worked or not :-)

For your information,
For a month now, sometimes I switch to the HDMI connection and, oh surprise, I have the TV on HDMI... not for long... the longest it lasted was 48 hours... it cuts out abruptly, and I switch back to AV SCART... I may have figured out that I need to turn on the Freebox first and then the TV for it to work... but it goes back... but from time to time, it comes back... it's in those moments that the expression "hope springs eternal" takes on its full meaning...

I have good news for my face :-)) After an automatic firmware update of the Freebox My TV is working again via HDMI, continuously, it’s been 15 days now... I don’t understand anymore...
