philips blank picture	Can't Post

Hello. I have a Philips 42PF7320 which has stopped working. The unit switches on, solid green light, no flashing, but no picture. ( screen lights up but blank background) I get two relay clicks, one slightly after the other and it appears that the screen powers up, but no blank picture and no sound. I have had the power board out and checked it, replaced a resistor which was blown on powr supply but cannot find any issues with the capacitors, no evidence of damage at all. Any ideas would be greatly appreciated Thanks

If you post in more than one forum and you update one, you should update them all. Wink
