My insignia receiver keep turning itself off stand by?

Not receiving lower channels with digital antenna with insignia 42 I had on previous tv AmanStino Ultra Slim Lightweight Smart shell Stand Cover with Auto Wake...

When an Insignia TV is locked, it keeps you from watching all of your channels by only displaying a black screen. Insignia TVs are locked from a single button command on the remote control, so it is easy for you to lock the TV by accident. Since Insignia TVs can be locked so easily, it's important to know how to undo this command and unlock the TV yourself. So, unlock your Insignia TV with the push of a button and once again enjoy watching your favorite programs.
• Find the lock button on the Insignia remote control. The lock button is located on the third column from the left on the second row from the top of the remote.

•Stand within operating range of the Insignia TV, then aim the remote at the TV's receiver and press the "Lock" button on the remote control.

• Aim the remote at the TV and press the channel buttons to make sure the TV is unlocked. When the TV is locked, it shows a black screen and does not allow you to view anything else. If the screen remains black, press the "Lock" button again. If this doesn't work, change the batteries in the remote and start over at step .

Keep checking Ebay. I hate that site, but sometimes they are a necessary evil.

It may be the button on the remote. Turn of the TV and remove the batteries from remote. Then turn on TV from the buttons on the set itself and see if it happens. The Insignia remotes are poor quality. Insignia TV's usually carry a 2 year warranty from Best Buy(Insignia is their store brand) if it is under warranty they will replace it. If not under warranty and it is the remote you could try a universal remote.

OK

Blinking indicates that the power source has shut itself down because another component has died and it's shorting it. Unless you have experience in electronics it's time to take the receiver to a repair shop.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Cause
• The speaker wires are frayed or sticking out
of the jack, and are touching the back of the
receiver or another set of wires.

Remedy
• Reinsert the speaker wires, making sure there are no
stray strands of wire and that they are inserted fully.


thank you

Ok, I had the exact same problem last summer, and Kevellen told me of a problem that Insignia tv's have: the circuit that controls whether the tv is off or on is messed up, and it can be fixed, but its not cheap.

Anyway, if the t.v. is still under warranty, I would say return it to the store and see if you cant get a new one, and from what I researched online after this incident, I will not buy an Insignia aver again.
hope this helps,
