He may just be giving up too soon. Again, does this happen on every channel no matter what is plugged into it?
If replacing the cables doesnt help, try giving sony tech support a call and see what they suggest. It wouldnt hurt to get a professional opinion. Plus if your warrenty has expired and they offer to repair it at a cost, im sure it will cost less than a new 40" TV
Not sure what country you're in so go to the website below and choose your country then look for their contact email or phone number. I'm sure they will be helpful, thats what theyre there for.

Have your TV model number (usually on the back of the set) and details
of the fault handy. They may also ask where you purchased it from.

Try reseating the LVDS cable.It runs from the main signal board to the T-con board at the top of the panel.

Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.

Are these vertical lines colored or do they look like static lines? Also are these lines present even on the no-signal screen? It sounds like an LCD controller problem but first I would like to make sure that its not the video precessing board. So please provide this info.
There's very little chance of an LCD TV having a "60 cycle hum". That problem was a hazard of CRT TVs and is rarely seen on LCD TVs and even when it is, it's mainly a problem with the RF feed and not the TV itself.
Try hooking up various inputs one at a time. For example try component input from a VHS tape player. Then try HDMI input for a HD player (Blu-Ray or HD-DVD). Then try a computer hooked up to the VGA input (set your video output on the computer for the native resoilution of your TV). Make sure you have the inputs selected correctly for each source.
The standard "refresh" rate for your TV is 60 Hz but that is a bit of a misnomer as LCD TVs don't used a raster scan for their display so their "refresh" is typically measured in miliseconds, in your case it is 8ms.
Your problem could be a power supply problem or if the lines are static, it could be an addressing problem in the ATSC decoder chip.
There are many other possiblilities but with more data on your symptoms, I wouldn't like to guess.
Hope this helps.
