Hdmi ports not working - Insignia 42" LCD Flat-Panel HDTV

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.

Yes,

When 1 HDMI port is broken most of the time all the ports are defect. This is because all the 3 HDMI ports are connected to 1 multiplexer IC. Only when the connector or the copper connection on the board is damaged the other two ports still be functional.

You still can use the other connections ( not HDMI) the should be working.

sounds to me like a bad HDMI cable. Just replace it.
If HDMI still wont show, move to another HDMI port. But based on having to hold HDMI cable with hand to steady the connection, it is either a bad HDMI cable, or a bad HDMI port on the receiver. Good luck

Not the HDMI port,it the HDMI cable is dead.If u have dead HDMI port holding the HDMI cable wouldn't work,make no difference.Change the HDMI cable will solved ur problems.

My best bet would be a port issue - see if another device will work plugged into that port. (Some HDTVs have a HDMI port strictly for Service and nothing else but a Technicians specified cable will work in this port, look at the Manual) Check to see if your TV is set to the same port as your connecting to. One will be HDMI 1, next HDMI 2 and so on, the input button on remote should switch from port to port, make sure port setting on TV is same as #port your connected to.

you need to go into your console video settings and setup for hdtv to use hdmi.

Not all HDMI ports support Audio or they do but only one way Audio out or Audio In. If you have an optical connection you can try that.

Hi.

To start ensure that each time you connect or disconnect the HDMI ports both TV and connected device are off.

Also ensure that HDMI input is active, as detailed here.

HDMI connectors carry voltage, and connecting the HDMI cable while TV or device is on may easily damage the HDMI port, making it unusable.

The HDMI 3 and Component 3 are separate input. The component input may work, and HDMI port may still be defective.

To test the port do the following:

Disconnect TV power cord, and connected device (eg. Receiver, DVD etc.).
Leave units disconnected for five minutes.

While power is disconnected, test connecting on port three a device that was previously working on HDMI 1. Also use a cable that you know is working.

Connect back power with HDMI cable already connected. If HDMI 3 is still not detected, then the port is defective.

In that case ring Pioneer at the number listed on the owners manual.This model is often advertised as only two HDMI inputs. Call Pioneer to ensure the third port can be enabled.

Try plugging hdmi cable into hdmi 1 on your TV, then open the menu on TV and find the place it lets you to make selections on this, such as Satellite or hdmi 1. One of these selections have to work.

does the hdmi port gets detected when you try in other hdmi ports.if not getting detected then it can also be fault in the hdmi ports.because as you said that hdmi port number 1 works.that means wires are proper.but other hdmi ports not working that means the ports are faulty if all the setting are proper in setup.
as the ports are soldered to the unit internally.if the soldering gets loose the connection will not get complete.so re-soldering is required to the loose ports.

if you are not familiar with doing this you can get it done by local repair technician familiar with this model .

You could replace the HDMI port on the TV, it's no different than changing a USB port card in your computer. But, finding the replacement HDMI port card for your TV can be tough. Try shopjimmy.com for parts.
