Panasonic Viera TC-50PS14 - 1 blink fault

[SadPanny]

Hello and good afternoon,

So my girlfriend has a Panasonic plasma and the picture is great. However over the last few months it's developed a problem with the power of the unit.
Initially when pressing power on the remote sometimes the tv would power on. Other times the tv power light would just blink once every few seconds.
Over the last few months it's progressively gotten worse to the point where we have to press and hold the power button on the tv and one in every 50 attempts turns the tv on. The remote only sends the tv into intermittent flashing and will never turn on the tv first try.
Once the power light begins to 1 flash sequence we can attempt to manually turn on the tv and it's hit and miss when it works. Sometimes 5 minutes sometimes and hour with or without unplugging.

It's definitely 1 flash code every 3 seconds. Any help is appreciated.. thanks in advance

Blinking once every 3 seconds means unknown error or stand-by voltage problem,which can be your case,i bet on capacitors failing or connections going loose over time,you need to measure what voltages are beeing fed from the power supply(P board) to the main(A-board).
50 attempts?you're persistent i tell you.
