Have TV Questions? Ask a TV Technician
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, have you tried unplugging the Pioneer for an extended period of time? ...and then plug back in but into a different outlet.
Note if the described "...red light in lower left corner blinks..." would commence immediately upon plugging back in. ...or only after attempting to turn on.
This would be indicative of an internal hardware issue or more particularly a failure in the power supply circuit; a low or missing secondary voltage.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
Still, please click HERE. Select your state/location and/or key in your Zip Code then click/tap on the Submit button. Next window would display NESDA certified / accredited TV Repair Shops.
