My hdmi ports are not working, even after trying out different cables. It used to function well before for two months since i bought the tv. what should i do ?

I will try a new main board first.

Change you hdmi connector.

Try a different HDMI cable first into all ports. Try every HDMI cable you have. Then try a different component into TV HDMI ports. If you are using the receiver to switch inputs, try running HDMI cable straight into TV. HDMI is very finicky. Some cables won't work or stop working for no apparent reason.

you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

never plug in hdmi when comp.is on you may burn your hdmi port

Ur tv some how causes HDMI 1 and 2 port hubs link together so changes back and fourth 1 or 2 HDMI hubs will not a difference.Ur tv have 4 HDMI hub ports wright?Tries not to used HDMI hub ports as like HDMI ports like 1,2,3,4 to as in sequences.Tries used like 1 and 4,2 and 4,3 and 1 as skips sequences might work for ur tv.Tries to hook up the PS3 system as the old format hook up same hook as PS2 format like used the PS station old RCA AV cable hook up.Then that should not causes conflict at all because now tv have two difference kind of format hook up.

If you just bought the PS3 use your composite cables that came with the system. Turn the PS3 on and go to the video settings, set up video input to HDMI. After you've done that plug your HDMI back into your PS3 and try turning it on. If that works go back to video settings and change the resolution to 1080p. If that doesn't work make sure your T.V. is on the same input that the HDMI cable is plugged in. If it is and still doesn't work try switching to a different HDMI port. If switching to a different HDMI port doesn't work try a new HDMI cable. If the new HDMI cable doesn't work then there is a problem with the port on the PS3 which would require a repair.

hi First, remember the old HDMI reset tech tip. Unplug all HDMI cables (one end will do.) Then remove power from all things in play. No, not just turned off but remove the AC. Wait 5 to 10 minutes, hookup re -test thanks

No, when I bought my new plazma tv, and unhooked my old DVR box, I had to go to my cable provider and inform them. they sent a signal and WHAM I was back in Biz.
