Re: Akai PDP4225M stuck on HDMI
The only suggestion i can make is disconnect the keyboard and see if the remote will change the source. The keyboard may have some stuck contacts so the remote and keyboard are fighting each other cause the tv to lockout but i'm sure others may have some better ideas. -
Re: Akai PDP4225M stuck on HDMI
only thing i can think of if MR Bill suggestion didn't work would be to try find if there's any firmware update to main board if not then only cure would be main board replacement
also just remembered some those Akai units were same as Samsung Model SPL4225K or very close cloneRon Driver,BSEE,CET,ISCET,NESDAComment

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.

Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.
The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.
I can't find any schematics... -
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..
