Ok darkened the room plug in, one click then flash of a few white lines then back to black. It can't be anything to do with the Y-buffers can it?Leave a comment:

Re: Samsung PS43D450A2WXXU power on fault
ok I notice that you get the samsung sound when powering on?off, I dont have this.
When I press anything on the remote the signal is getting to the infra red receiver because the LED is flashing just nothing happens.
No picture of any kind.Leave a comment:

There is a whinnying noise coming from the power supply, presume its the transformers, changes pitch when the LED switches on & offLeave a comment:

Hi Tom
Did what you said with a 100 ohm, relay swithched on and off 5 times but quicker than before do I need a bigger resistor to get it stay on?Leave a comment:

Re: Samsung PS43D450A2WXXU power on fault
Do I keep the ribbon cable disconnected from the mainAV board when I put the resistor in?
Keep me posted with how you get on tomorrow with you pals unit, a big thanx for what you have done so far

Samsung PS43D450A2WXXU power on fault
Hi everyone,
This is my first post
I am not TV tech but do know how to use a multimeter.
Here is the situation:
Mother in-law has a plasma, 16 months old, that is now out of warranty.
On initial power up, i.e. plugging into wall socket, the units relays click on/off five times then the standby light flashes v.quickly twice 5 times then pauses then repeats. I have trawled around this forum and done the usual check for domed leaking caps but there is no visual damage.
I have tried disconnecting the x board but it would appear that...
No activity results to display
