All HDMI Ports showing no signal

Everything was fine last night, this AM all HDMI ports show no signal, I have 55" LCD about 15 months old, has worked great till now. I have my cable box on port 1, Roku player on port 2, a Blue-Ray on port 3. I have cycled the devices, removed them all and replaced one at a time. I have reset TV to factory, turned off for 90 mins and restarted but no signal still appears on all HDMI ports. All other inputs function properly, all devices work as should thru HDMI on 2 other TV's. I have tried diferent devices, a 2nd Roku player, a DVD player none will function thru HDMI.

When you cycle the TV thru the HDMI ports it will turn the Blue-Ray player on since this is a INlink device....

Is there something that will drop all HDMI inputs?, is this an easy fix ?, or am I about to be screwed by service charges?

Re: All HDMI Ports showing no signal

Hello snavenala,

Welcome to Community@Insignia™!

You said that you turned off your devices and disconnected and reconnected them, but have you also unplugged them from power? A complete power-cycle with removing the TV and other devices from power for a few minutes will reset the hardware.

 

If power-cycling doesn't resolve the problem, it's likely that your TV will require repairs. In-home service can be obtained by calling our Product Support team; contact information is available via the Support & Service link at the top of this page.

Regards,
John

Re: All HDMI Ports showing no signal

I had done multiple full power cycles on all devices, including removing each of them fully from the power source, (I consider this a standard action as part of any electronics reboot), I just found it suspect that all HDMI ports are experiencing the same defect after the system was in stand-by over night. I thought that this may be a problem that was known  to occur with this TV and I could replace a board or other component without the added expence of involving service personel, since the cost of the TV and repair could now become similar.

Thanks for your previous response.

I have the same no signal problem with my android TV box but not with my cable box which I have to unplug and replug in order to work. Need help. Rebbooting did not work.

Hello icamareno,

Welcome to Community@ Insignia™!

Have you tried switching the HDMI cord between the 2 devices to see if one of the HDMI cords have gone out? Also, have you flipped the HDMI ports the devices are connected to to see if one of the ports on the tv has gone out?

My 32" is doing the same thing. I thought it was my computer docking station going out, but as I've tested different devices in different HDMI ports on the TV, and with different cables and combinations, I'm convinced it's the TV going out. THat's NUTS, it's only a few months old.

Hello stephensaj,

Welcome to Community@ Insignia™!

If you are having the same issue from multiple source devices through multiple HDMI ports, it does sound like the Input board has become faulty or picked up damage. I would suggest having the TV reviewed under the 1 year manufacturer warranty. If you have a copy of the receipt, or gave a phone # during checkout they can use to look up the purchase, you will just take the TV into your local Best Buy store to the Geek Squad desk for warranty review.

Re: All HDMI Ports showing no signal

Thanks, I had the Geek squad fix the TV, it did need a new board. - Just this last week, the same TV is showing the same issues. I want to flush it down the toilet!

 

There are no moving parts, how can it just stop working like that? Usually even cheap electronics work. - The old TV, store-brand Dynex, is what I have to use for a computer monitor now. Even though it was cheap with little frills, it still does what it's supposed to.

I'm so mad at Insignia and Best Buy for offering such junk.

To Whom should I mail the pieces when I lose my patience with this TV?
