Hi ! I have a panasonic viera tv model tc-p58vt25 and the screen just went off ...the power light is blinking below but is not turning on again.... I try unplugging it and plugging back again with the same result... what should I do ?

Technician's Assistant: Is your Viera connected to a surge protector or power strip?

It was before... but not now

Technician's Assistant: Have you tried to power reset your TV (unplugging the power for 1-2 minutes, then plugging it back in)?

I tried that ... same result

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning 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 2010 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 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 you’re considering repair at a local shop, you’ll find a typical repair to be around $400 for diagnostics, parts, and labor.

For a tv of this size/age however, replacement will make more sense. You can get a brand new 4k LED tv with a fresh warranty in the $500 range.

I can help you with finding parts, finding a repair shop, or recommending replacement options, if desired.

My apologies for the news,

Nathan

Thanks Nathan, I tried your suggestion already and didn't work
TV Technician: Nathan, Installer replied 3 months ago

You tried this complete and exact process? The timing and sequence is critical, so if you did just a brief unplug or not the whole process, I'd suggest trying it again.

If still no change, then we're back to a hardware fault and it is time for a new tv.
