Thank you for confirming. Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, often a faulty power supply or main/control 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 2006 model tv, that type of failure wouldn’t be surprising. This tv is significantly past its service life at this point, and plasma technology is long obsolete. 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 outlet2) Wait at least 1 hour (60+ Minutes)3) Press and hold the power button (on the set, not the remote) for 60 seconds4) 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 could include dismantling the set (removing the back panel of the tv), diagnostics testing with a multimeter, changing out boards as needed, and possibly desoldering/removing and soldering/replacing individual components. 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 however, replacement will make more sense. You can get a brand new LED tv with a fresh warranty and double the picture quality in the $600 range. 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

thanks i will try what you have advised - interesting thing is this happened approx 6 months ago and was idle but hooked it up again there where no issues
Expert:  Nathan replied 1 year ago.
Yes I did see that, and that does still point to an electronics failure. You may find that it comes back on after a short reset, and will work for a bit, but will keep happening and getting worse and worse until it won't come on anymore at all.
