Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority. Sorry to hear you’re having trouble with the pioneer. 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 2003 model tv, that type of failure wouldn’t be surprising. Electronic components such as electrolytic capacitors can fail with age, regardless of the actual hours of operation. There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation1) Unplug the power cord from the tv2) 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 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).If you’re considering repair at a local shop, you’ll find a typical repair to be around $500 for diagnostics, parts, and labor. The bigger is though is the availability of parts. Pioneer stopped making tvs entirely about 6 years ago, and stopped supporting your model years before that. Any repairs would be at the component level, which is very involved from a labor stand point. Further, these pioneer plasmas are known as some of the most complicated tvs ever made, most techs won't even touch them, so finding one with pioneer experience is difficult as well, and any parts would have to be used/salvaged. While I recognize that this was a very nice, and an extremely expensive tv, when first new, technology has advanced considerably since then. You could buy a brand new LED tv
with a fresh warranty, upgrading to a 1080p picture, full hdmi
/hdcp compatibility, and a fresh warranty, for the same price or less than you'd spend on repairs. 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.
