HDMI issues

[kerching]

Not my area of expertise so I thought it better to ask the collective
LG TV
Samsung BluRay HDD
Portal
Firestick all connected to HDMI

All worked fine, then yesterday NOTHING on any HDMI port
Turned everything off and back on, obvs
Swapped all ports around, still nothing
Reset TV to factory settings
Nothing
Set up Simplink and each HDMI port can 'see' what's connected and correctly names the connected items
BUT whenever I click on an HDMI port on the input section it says 'no signal' no matter which of the 3 I select
TV works fine in stand alone

Am I missing something blatantly obvious?

Sounds like a fault with the board then. How old is it?
Model no?

 

[kerching]

Possibly 6/7 years old
3D smart TV
I'll get the model number tomorrow

All of my LG's did a firmware upgrade in the last couple of days, maybe it's a failed update? I dont know how you can force it to redo the update.
Maybe time for that OLED TV you've promised yourself!

Search on manufacturers website or google specific issue with model number?

I had an older LG tv once ann no s one day the screen just went blue for no apparent reason, so decided I’d never buy another LG. Had Panasonic since and very impressed.

Thats a very small sample to assess LG is no good and ditto Panasonic is brilliant.

We currently have 3 x LG TV's in our house, just ove 2 years old and no issues. Previously we've had 8 LG TV's, even early Plasma ones again no problem, only replaced due to newer technology giving a worthwhile upgrade. The previous lot of 3 were all involved in a flood in our house, all of them received a prolonged heavy shower when a plastic pipe fitting failed. Once fuses were replaced allowing the time to dry out, they all worked fine. They were replaced by our insurance company as standard practice but amazing they still worked.

Whilst I dont agree with this guys logic, allegedly it works and some of the feedback confirms it.

I would be surprised if a standard hairdryer gets hot enough to re flow solder, and in any event you would want to flux the board first?

I doubt it was re flowing the solder and I doubt it will be a reliable permanent fix.

Yep, hot air soldering is typically 450 to 500 deg C on my station, no way is a hair dryer reflowing solder. Maybe driving out some moisture? Hence why I said I didnt agree with his logic, several people responded to the video on feedback and said it had worked for them.

What did you do to restore operation?

 

[ProDave]

If it was the hairdryer trick that restored it, I would mark that down as a poor unreliable design, offload the set while it still works and buy something completely different.

 

[Murdoch]

Have you tried changing which ports these devices are plugged into ?

 

[kerching]

Yep, that was first thing I tried

Other priorities now as wife has just had her right leg broken by a horse kick

I'll get back to it after mondays fracture clinic

Man of many talents, doctor, nurse and sparky. Hang on in there, fingers crossed, hope all goes well.
