Re: ps50q7hd
Only a couple of things I can think of and that's to go into the service menu and look for something called HDMI MP DLY or very similar, it should be set to 9, if it's sky high HDMI ports can drop out altogether and won't show up, make sure it's set to 9 or 10, see if it helps, if not a board change might be needed. -
Re: ps50q7hd
To access the advanced menu, you need to:
Power off on remote.
Press Info, Menu, Mute, Power in that sequence.
This brings up the service menu.
Please then proceed with care.
Scroll down to each option in the submenus - do not use left/right arrow to navigate across the menu
Press menu to return to the main service menu screen.
make sure you right down anything you changeComment

Re: ps50q7hd
I suppose you've tried turning both devices off, hook the cable up, turn TV on, turn source on then select HDMI source on TV? Check output resolution?
That's all the ideas I have. I Did not see any special setting in the service menu.
service manual
9 HDMI/DVI IN
- Connect to the HDMI jack of a device with HDMI output.
These inputs can also be used as a DVI connection
with separate analog audio inputs. An optional
HDMI/DVI cable will be necessary to make this
connection. When using the optional HDMI/DVI adapter,
the DVI analog audio inputs on your TV allow you to
receive left and right audio from your DVI device.
(Not compatible with PC)
- When connecting this product via HDMI or DVI to a
Set Top Box, DVD Player or Games Console etc,
make sure that it has been set to a compatible video
output mode as shown in the table below. Failure to
observe this may result in picture distortion, image
breakup or no picture.
- Do not attempt to connect the HDMI/DVI connector to a
PC or Laptop Graphics Card.

Re: ps50q7hd
This is a common fault with older TVs, and you can blame hollywood / copyright industry...
They insist on encrypting the connection between the set top box/bluray and the TV because they don't want it to be copied. If the secret encryption keys used to encrypt this are compromised then the data can be copied. The keys are usually compromised after some time because people copy them and the standard is horribly broken allowing anyone who knows what they are doing to copy said keys after monitoring the HDMI data for around an hour or two.
End conclusion is TVs that are older than a few years can have their keys revoked (banned permanently from showing HD content) and the boxes will refuse to send them HD content. Yes, this means any TV nowadays because it turns out once the signal reaches the main board it's completely unencrypted from main to t-con/panel/PDP... and there are full datasheets describing these formats in my signature for example and across the wider internet.
Even though PirateBay and other sites are full of pirated movies, sports, TV, often less than two days after release - in other words, it's not making any difference - they continue with this "f**k the customer" policy.
Only thing you can really do is get a "HDCP stripper" - like HDFury - but they cost a lot of money...
NOTE: eBay has banned HDCP strippers because of the industry complaining, despite them not being very complex at all... the HDFury retails at $250 but looks to contain less than $10 of parts. http://www.3dfury.eu/images/hdfury2_5.jpg So if it were not for the 'bay banning them then you'd have cheap ones from China in no time... and the industry would hate for their broken, expensive standard (£1.50 per bluray player, £0.10 per disc, £3.00 per TV) to seem even worse!

Re: ps50q7hd
Aging panel? I worked on one of these and had the same issue. Gradually got worse as it running on a black panel and I think with the blue screen on it was bad too in selected areas on the panel. I tried forever to adjust it out with little success. Was not too bad watching it normally.
As for no PS3 or any HD, I don't have an answer but if the output resolution is correct for what the TV can process I'm at a loss but that message is probably being sent by the skybox and the image is good so something is working.
Not something I've had to deal with.Comment

Re: ps50q7hd
Yeah, looks like panel aging to me. I couldn't get rid of it on my Q96 properly... luckily the Q96 was a freebie. I would never pay much for one of these sets, too many problems.
Same cause as LG panel aging prematurely, but there's no firmware update for these...

by aliougmI 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... -
by japlyticWith 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.
An examination of the HDMI CEC wiring...07-10-2022, 09:48 PM -
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..
