Just to update my first post. I changed the flyback transformer which most posted as the problem but still not working. It will power up now but screen is still black and the blink codes have changed from continuosly to 4 blinks and then 7 blink codes. which according to the chart could be broken ic5004,ic512, q8008.How do you check which chip is broken or do you just change them all? any info would be apreciated thanks Scott
