When you first plug it in, the standby light is continuously red. You leave it for a while then it flashes red, a few times then a pause (not sure how many).
If you try to switch it on, the light flashes green very fast then goes to solid green as if the tv is on but no picture is up. If you then leave it for a while it goes back to flashing red.
I can switch it on now and wait but I'm not sure how long it will take.
I switched it on and about 3 minutes later it has just switched the standby light off itself. No blinking this time
Let me know what the most likely culprits could be. I have switched it on now so it has a solid green light but no picture. I'm waiting to see if it goes back to the blinking light and what pattern it gives.
Is this typically a problem that would worsen from doing it occasionally to not switching on at all?
I now have the red blinking light back. It blinks 13 times before pausing. Does this help towards identifying the problem?
It looks like I've fixed it. Threatened it with a multi-meter to test the connection. After unplugging the power supply from the circuit board and plugging it back in, it seems to work again!
Thanks for your help.
