keep your reciept throughout your warranty period.

What you need to do is get a copy of your transaction fron your credit card statement and call the walmart headquarters and ask a friend if they will be able to take you to the store ,

Sounds like your fiddling may have shorted out the main board of the TV.

Not to say that this wouldn't have happened eventually, there's a good possibility it was defective from the start.

If you have warranty, try to go through that, you should be covered. Otherwise, for a 26 inch, most likely not worth repairing, good luck!

The repair bill will be $200~250 range if you can find the shop that willing to try to fix it and find the parts for you.

usually the first thing to check is your connections to the tv , if good you may have a power supply or backlighting problem. if connections are good, unplug it first ofr a few minutes the plug it in and try it again. if bad call for service.

I have to tell you that I'm finding that this is about the life expectancy of the first generation LCD TV's. It could be fixed/repaired for between $100 to $200 at a good TV Service Shop.
You may just want to put that money into another TV!

The CCD image sensor chip is faulty, take it back for replacement. You do not need a receipt, If you paid by debit/credit card, use your paper statement as proof of purchase

could be one of two problems, either the lcd back light, which a new screen is needed, or the control box, both run about 200 dollars from polaroid, I have a 32 inch screen, I bought it cause polaroid said that was my problem only to find out that it was the control box.

Try a reset frist by unplugging for 2 minutes then restart the TV. If you only paid $300 for the TV you will most likely pay more than that for repairs and parts to fix it otherwise.

Hello DEBM,

 

The problem with your television appears to be in the high voltage power supply or the low voltage power supply. The set tries to come on but the shutdown circuitry turns the TV off. The shutdown circuit is a protective measure put into place to prevent overcurrent and overvoltage conditions by shutting down the TV when these conditions exist. If you do not have a background in electronics, might I suggest that you have a TV technician to come to your location and work on the TV.

 

I hope this helps

Thabk you,
