I have sound when connected to either input but there is no real picture. There is "scrolling color lines" no actual picture scrolling. Problem started when the power to house was going on and of during a t-storm. Picture works fine from AV1 and the side input. Have tried new DVI cord and other video cables for AV 3, no luck. I tried unpligging the tv for a few minutes, no help. Then unplugged the tv overnight, no help.

Re: No HD picture from AV4 or AV3
You power supply has a problem in it. If the electric ever starts to go on and off again, you really should disconnect the main to the house or purchace a standby power supply for the TV set like the ones peeps use for their computers. They are inexpensive these days and they really do work and save lots of money. Now about the TV set. Without a service manual and the know how to work on solid state electronics and printed circuit board, you should seek out the assistance of a service person for this type of repair, unless you do know how to use a multimeter and read a schematic diagram. Good Luck

av 1 is the source input for the tv
there should be av 2, 3 4 etc and each one isa for a different input item
for example av1 is for the tv -aerial , av2 may be dvd input , av3 may be x box, av4 home theater

Well, lets start here first. I would like you to look at the input jacks for a/v3 and a/v4 and see if they are color coded RED-GREEN-BLUE. or if they are just YELLOW-RED&WHITE (audio). If they are RGB then just buy RGB cables at your local Best Buy. If any are just Yellow and Red & White then those are just regular composite video the same as the old vcr's. You can't make A/V jacks work like RGB component jacks.
On this TV there is only one input for any HD resolution. Input # 5 is the component input i.e. red/green/blue cable. Just get the correct cable and match colors from cable box to TV this will allow the TV to display 1080i resolution ( only one this TV supports ). FYI you will also have to connect the red and white cables to the appropriate inputs to get any sound because red/green/blue connectors are just for video display not sound. Once your connected you'll be able to access video # 5 be sure to set your cable box to 1080i resolution also. I hope this helps later J.
You may have shifted the input board a little while replaceing the IC's. Double check every plug and connector, not just by visuale inspection, but by going and removing and replacing every connector. I have had problems like this in the pasy and have learned the hard way, everything is not as it looks. Good Luck
