It is because the PC video resolution is too high for the TV to display, you need to set your PC video resolution to the native resolution of this TV, see you owner manual.

SOURCE: HDMI PORTS DONT WORK

Hello,

You will need to replace the main video logic board, its part number is either EBU60852909 or EBU60852911. These two board are direct replacement parts. There are several boards available on Ebay such as this one: http://www.ebay.com/itm/LG-46LD550-UB-Main-BPR-Total-Assembly-EBU60852909-subs-to-EBU60852911-/150895037335?pt=US_TV_Boards_Parts_Components&hash=item23220b8b97

When i plug in anything to the HDMI ports on my TV i can get audio but no video. This was working find until the other day, is there a way to reset this?


best bet is to buy a new HDMI cable and if it works in your tv then you know it was the original that was faulty but if not then the problem will be the TVs HDMI slot... if so then try testing the HDMI cable in the multiple HDMI slots on your tv (also trying both ends in each device) and if its still not working then try the TV setting but i dont think there is a setting but its worth a try :)

Connection problems with my hdmi with my ps3... need help its saying no signal


I recently experienced this issue with a ChromeCast and my TV set. The TV refused to "see" the ChromeCast so...

What I did was to turn the device on turn the TV on and set it to the HDMI port ........THEN plugged it firmly into the HDMI port and it was recognised.

It is something to do with the TV's ability to recognise the Sync signal from the device, it seems like it needs a kick up the britches to get it to work with some things.

My Vizio VU37L HDMI ports not working. AV ports work. Heavy lightning storm last night, TV was off when I went to bed, on when I woke up.


If you send the board to us we may be able to fix it.

What you're looking for is having to replace the small SMD IC that the tracks from the HDMI ports lead to.

Sometimes that is all it takes, other times it needs more and just today I've had a case where we just couldn't do anything as the damage seem to have spread to the large processor.

(it wasn't on a Vizio board, it was on a Sanyo, but the concept is the same)

HDMI Port problem ? blurred video and no audio.


If one port works but the other does not I would say the set has a problem.

Note: sets with HDMI are very sensitive to having those connections made with the unit or units powered up.

A suggestion would be if one works but the other does not try another device which uses HDMI in the suspect port==stranger things have happened.

All hdmi connections not working on a samsung ue40c8000 every thing else seems to be ok. done a factory reset does this sound like a new board costly? regards. Norman


The tv Samsung refurbish main tv Turner signal board will set u back like $120-130 bucks + shipping and handleling and u must have to have some basic mechanicals skills like take things aparts and putting it back togther again to fixed this tv just for the used of those HDMI hubs ports again.My questions to u is?Does ur tv used 100% must require those useages of those HDMI hubs ports.Not just used the Samsung tv as is.My Samsung tv have the same problems.I just work around it by skipping all the useages of all those HDMI ports hubs of the tv altogther.Most poeple just used about like 3 HDMI ports hubs for like a HD cable box or DVR cable box and a PS3,WII games systems or Blu Ray DVD player.All these devices can go through hook up for like a RCA component cables hook up like AV1,AV2 and last one a HD hookup by a RCA component cable just add 2 more components wires like a green and purple connections or just buy a set of RCA components cable that design for a HD output.I did that,must more reliable set up too.Because those RCA components cables set up have more plastics in it connections for insulation holes for little shorts and sparks better than those HDMI ports hubs and HDMI cables barely help and the plastic for insulation is a joke almost non exiten.Those all dam HDMI ports hubs are all link into one path way on the circuit board,one dies or got shorted all dies and get shorted out.

HDMI PORTS NOT WORKING


Try visually inspecting HDMI’s that are not working. Occasionally, pins on HDMI connectors are getting bent or pushed-in. If you can spot the damage, fix would be to replace HDMI connectors. If connector are not damaged, then main unit of the TV has to be replaced.

My xbox 360 elite video port went out on my previous xbox, and on the one i just got. it could be your video port on your xbox or it could be the your tv. Hdmi cords usually dont go out so i dont think it could be that. A way to check if its you xbox would be to try the regular cords that you get with your xbox on the same tv and see if it works. If it doesnt, try the same thing on a different tv. if it doesnt work on that tv either then its your xbox. if it does work, then it must be the other tv.
