Hello,
My Plasma TV will not turn on, Please help!
I need some advice with regards to my plasma TV, after a lot of googling I thought that blown capacitors might be the problem, but on visual inspection they all seem to be fine, so further searching led me to this forum where I thought I would find the answer, but after reading a lot of other posts can't seem to find exactly what I am looking for, so as you seem a friendly helpful bunch I thought I might as well ask, as you never know.
My electronic knowledge is basic (I built a radio, a calculator and some knight rider flashing lights at college 20 years ago on a breadboard) I can use a soldering iron and have a multi-meter.
I have owned the TV from when it was new at least 5-6 years now.
The last thing to happened before it stopped working, was that the power got (accidentally) switched off at the wall socket while the TV was on, the TV was plugged into a basic 4 socket gang which was plugged into the wall (no surge protection)
I hadn't wanted to do this but also thought that it would be fine, so I didn't pay too much attention to the colour of LEDs when I turned the power on again some 3 hours later,
although there was defiantly some LED activity and some clicking this one time the set would not turn on.
After unplugging it for 24hours, I get no LEDs and not even a click.
What I have noticed which may or may not be relevant is
Whenever I have connected the power cord I have heard ‘arcing' just before It is fully inserted
When there has been a power cut in the past the TV has had to be unplugged and plugged in again before it has worked.
Upon opening the back, what I have noticed is a light comes on briefly when I connect the power
‘5V ST CON' and the Coils - L1102, L11O3, L11O4.( 26UH 1UEWPHY 22.5TURN YL-9N 0.4) Look like they may have overheated?
Any Help would be greatly appreciated
