Sorry to hear you’re having trouble.

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, most often a bad A board board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).

This could also be the result of age related wear and tear, as a 2010 model tv, that type of failure wouldn’t be surprising.

There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation
1) Unplug the power cord from the tv

2) Wait at least 1 hour (60+ Minutes)

3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.

If this reset process does not work, it would unfortunately confirm an internal hardware failure.

This is something that would require repairs to correct; if you're thinking about a do it yourself repair, you'll need to be comfortable and skilled with electronics repairs, which would require dismantling the set (removing the back panel of the tv), diagnostics with a digital multimeter to test voltages inside, changing out boards as needed, and possibly desoldering/removing and soldering/replacing capacitors (a common failure point). To give you an idea, a new A board is about a $150 part, but they are difficult to find.

If you’re considering repair at a local shop, you’ll find a typical repair to be around $300 for diagnostics, parts, and labor.

For a tv of this size/age, replacement often makes more sense, as you can get a brand new LED tv with a fresh warranty, in the $500 range these days.

Depending how you’d like to proceed here, I can help with finding parts, finding a repair shop, or recommending replacement options. Just let me know.

Best regards, ***** ***** for the news,

Nathan

I tried the reset process and it did not work. After the reset, it blinked four times over and over. I turned it off and on. Then it went back to flashing ten times.

Thank you for trying.

Unfortunately that does confirm an internal fault that will ultimately require repair/replacement.

How would you like to proceed?
