I have a 37" LG lcd flatscreen thats about 2 years old. When the tv is turned on there is a delay in signal transmission from the cable box. When the signal is received (about 3 minutes later) it is followed by a really loud static sound (about 20 seconds) the delay seems to be getting longer and the only way to avoid it is to leave the tv on all the time only turning off the cable box. Comcast replaced the box and Ive even changed the composite cables to hdmi. Please help.
It is not that rare to have a few secound delay but it sounds like yours has some componates that have gotten alittle hot at times and now take longer to come up if you haven't put a surge protector on it I would do so . To day with all the brownouts and power spike the newer units can not handle this couse of the componate being a lot smaller and as we put more and more ecectronic in our homes we create are own power drops the only way to help this in most homes is to use surge protectors.

Your main pcb could still have gotten damaged due to the defective caps. The reason you still have audio through the optical is because it is a digital signal only. It is not running through the audio amplifier on the main board. I would suspect either the main pcb or the speakers them self.
Their are a lot of things that could be wrong with your TV. The most commond would be your power supply or your signal board. If you look at your power supply carefully, You might see some capacitors that look like they blow up. If that's the case then replaceing them might fix your problem if not then you might have to get a whole power supply. You can get parts for this TV at www.interliquidparts.com

Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them.
You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.
Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable
