No sound. Brand new. Out of the box it worked great. Tried to set the time and the sound quit.

take it back if you work on it you will void the warranty !!

These blinks [flashes] are fault indication (Error Codes).From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.This will make repair easy.These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times.Count it carefully.If you wish to get some details, check the site linked here.It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.Viewing it in "Mosaic" or "Sidebar" will make surf easy.

This Orion TV made by Sansui was bought by me two weeks ago. It didn't last a week. The sound was terrible, picture was great, and it wouldn't hook up to soundbar without hearing a long delay in sound (A/V or Digital output tried two). I contacted their customer support twice, they were awesome. Told me this model has know issues and said to just bring it back. I found another TV for same price ($399) and same size (46) but it's LCD not LED, better picture and great sound! It is Insignia don't remember the model #. Bought at Best Buy (their house brand).

Have you tried replacing the battery?

HDMI very commonly creates loss of sound problems. A few suggestions: (not knowing the model or brand) The first is that HDMI does not like it when connected with the unit/s powered up and on.

If from a Gaming unit disconnect and reconnect with unit off.

Also if from a cable or sat box do the same---unplug the box and hookup and hook up again and plug box back to power--see if a reboot will restore audio.

Not a sure thing but in our shop we use several set top HD boxes connected to sets being "cooked" or tested.

One day (first time I had seen it) we had 3 plasma sets running out of the same box---one had audio and 2 did not---all three were same brand and model---unplugging the box, waiting a few minutes and plugging back to power---box booted up and all 3 now had sound.

Other possible reasons can be ruled out if the HDMI works on another set etc.

Some sets will have a software/firmware upgrade available for issues like this also.


Best answer here with the information given.

My DTA1050 worked OK. Then, after a period of non use, it would not work stating no signal. The antenna tests OK on a digital TV.
These things simply die, and Access has our government money!

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

I am assuming you have tried new speakers on used unit on both A & B choices. Have you tried your new speakers with old 2802? If they work OK with old unit, you have problem with amplifier in used unit. Take the used 2802 to a reputable shop and have it thoroughly tested. Perhaps it is just a loose connection.
