Customer Question

I have a Philips 42PF5321d/37 plasma tv.
JA: Thanks. Can you give me any more details about your issue?
Customer: morning when it came on as usual then went dark. I had to unplug the television and plug it back in. then it came on again, but for only about 15 minutes, then went dark again. some sound 1 and no sound the second time. Does it need a new power supply, or could it be something else?

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.

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, most likely a faulty sustain board 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, especially for this brand.

This tv is significantly past its service life at this point (by about double) and plasma technology is now 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 outlet

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 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 attempting to repair yourself the chance of success is low, as parts are no longer readily available.

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

In either case though, repairing the current issue will not extend the life of the tv significantly, as other components are all past their designed lifespan as well. You may get a few months or even a year out of it, but it would not be expected to last 10 more years, or even a few more years at this point.

For a tv of this size/age, realistically, replacement will make more sense. You can get a brand new LED tv with twice the picture quality and a fresh warranty in the $300 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

Please note:

I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.

Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately. Rating 1 or 2, or not rating at all, does not produce a refund, it only penalizes me for trying to help.
