Does anyone know how to repair the HDMI on these boards? I tried heating the chip already with no luck. I got no signal on the screen.

Re: 50pn6500 LG Plasma No HDMI
All of the solder balls need to get hot enough to melt around 217c/422f. If you were under, then try again, if you were too much over then you've probably killed the chip or it was dead already. -
Re: 50pn6500 LG Plasma No HDMI
Have you looked at the pins in the HDMI socket housing to ensure they are not damaged.Willing to help but I'm no expert.Comment

Re: 50pn6500 LG Plasma No HDMI
take a look on the downside.. you will find the pins even just heat one by one with soldering iron will do the job,, but need flex but on all pins to avoid short contact.. or just leave it and living with it if the set belong to youComment

Re: 50pn6500 LG Plasma No HDMI
Is it possible to do a firmware update if it's a firmware issue?

I have problem with my AVR(Marantz SR4003) HDMI board issue. I connect to my TV but screen color distorted,see attached picture.
Connection as below:
Set-top box HDMI output >AVR 3 HDMI input/one HDMI output>HDTV HDMI port
If I bypassed AVR then HDTV screen color be good.
I take out HDMI board from AVR and check services manual the schematic shown the HDMI signals path:
3 HDMI input port > SIL9185 chip(HDMI switch) > SIL9033 chip(HDMI receiver) > SIL9030 chip(HDMI transmitter) > HDMI output port
I replaced all... -
With a setup including a TV and AV receiver where HDMI Consumer Electronics Control (CEC) and Audio Return Channel (ARC) functions were working, these two functions stopped working after changing some connections (not the one between the AV receiver and TV), so I believed it was a corrupt setting in the AV receiver or TV, but when I disconnected a passive DisplayPort-HDMI cable (which a Multimode DisplayPort connector supports HDMI with a low cost passive cable or adaptor) connected to a home theatre PC, HDMI CEC and ARC functionality was restored.

I have this TV hooked up to only an AppleTV 4K and a Creative soundbar. Originally HDMI-CEC and HDMI-ARC wouldn't work at all, I replaced all the HDMI cables with decent UGREEN cables meeting the latest standards, now it all works perfectly but once or twice a day the TV itself reboots while watching a program, the AppleTV keeps running. I haven't fully pinned down whether it is ARC or CEC causing it yet. All are running latest firmware.
I assume it is just HDMI-CEC being buggy as usual on a shitty Vestel machine, but can anyone think of anything I can try before disabling it? -
LG LCD TV picture comes on intermittenly using hdmi port.The sound is on permantly.The hdmi ports looks fine and soldered in securely.The 3.4v coming to the main board is not present(not sure if will affect the hdmi port or where that voltage goes.)The hdmi cable is fine because it works on another tv.The ceramic caps connected to the hdmi controller ic is reading 39 ohms.Could the hdmi controller ic be faulty(feels very warm to touch).The RCA jacks work normally .Thank you in advance for your assistance.. -
I have an older Pioneer receiver (VSX-44) that's been dropping the HDMI output (black screen) for a few seconds every few minutes. Setup is HTPC -> Pioneer DVD HCMI in -> Pioneer HDMI out -> Samsung TV HDMI in, all with cheap HDMI cables that have never caused trouble before..
I initially found a lot of play in the receiver's HDMI inputs and output so I kind of squeezed them back into shape and they're making a tighter connection, but the problem persists.
And also, often, the HDMI will drop out in exactly the same way (black screen) just as my central air...
