Hi, I bought an LG 22LG3000 LCD TV from Comet last week and I've been getting an intermittent problem with the TV blinking, it can happen almost randomly but once it starts it doesn't seem to stop. It can happen after you switch it on or if you change channels. It only seems to happen with the devices plugged into the AV socket, as it happens when using our standard SKY box connected via a SCART lead. I have tried 3 different SCART leads, both AV sockets and also a standard SKY and a different SKY Plus box and we get the same problem. I have taken it back to COMET for an exchange but they are not being at all helpful and just put me onto an engineer who said switch the SKY box off and on again. Which obviously made no difference. They are basically refusing to exchange even though it is well within the 28 days since purchase. Wondered if anyone else has had this problem with their LG LCD TV and if there was a fix. I need to know ASAP as I don't want the 28 days to run out.
