RCA 46" LCD TV - HDMI Stopped working overnight

HDMI port was fine when we turned the TV off and then did not work the next morning. All three ports say "Signal unuseable or undetected." We replaced the HDMI cable but still had the same problem. The component cable and regular RCA ports seem to work fine. We are running it with a DirecTV HD receiver that is ~1 month old, as is the TV. Any ideas?

    I have the same problem with my 42" RCA. The HDMI ports worked for a few weeks then they just stopped. For a while the BluRay HDMI worked while the one hooked up to my Time Warner box didn't. I tried switching them around and getting new cables and getting a new box and still I have nothing. At this point I want to drop-kick it into the ocean.

Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.

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

46" Samsung LNT4661FX /XAA LCD TV volume problem.


If sound on one HDMI and not the others---all three should go to the same board--either something is not connected inside or the replacement board is the issue---Samsung is known for making boards with the same part number on them that from week to week have different features or do not have certain features.

Try to trace where the working input goes and if to same board as other two you know what to suspect.

Both HDMI ports are bad due to lightening strikes. What do I need to do to fix this? Can you suggest part numbers?


The main tv Tuner signal board have problems and all those HDMI insert ports are shorted dead,those HDMI insert ports are put on by wave soldering machine and fused by iron core solders joints to the main tv Tuner board itself.These HDMI insert ports are not replaceable by hand soldering equipments or can buy those HDMI insert ports individually anyway.Tv still work wright?Yes? Why don't u just skips the used of those HDMI insert ports all together and tries used those RCA component cable connections like AV1 and AV2 on the tv.Or u must have some mechanicals skills and like take things aparts and putting back together again?Yes?Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv main Tuner signal board for the replacement to able to used those HDMI insert ports again.I have the same problems with my Samasung 46" all my HDMI insert ports are dead too,but the tv still functions.That what i did used RCA cable components connections for my cable box and blu Ray player.
