Blue waves My TV just started showing blue waves (lower 1/3 of screen) and the color has more blue then any other color. Text is doubled with the color blue. Is it worth fixing as the TV is 6 years old and how much roughly would it cost to fix.

You need convergence circuit repair. The cost depends on where you live and who you call.

In Calgary, Canada typical TV shops want $300 to $650 for convergence repair. They will include cabinet damage and wall scratches for free.

It is a difficult technical repair to attempt as a rookie tech. It is even more difficult if alignment is required or any secondary problems are encountered. If you have no tools, no experience soldering or doing electronic repair; you may end up with scrap or paying a high price for someone to fix after your attempt to repair.

Most likely it is the Blue CRT Driver Board or the Blue CRT failing. There is no quick way to varify unless you call a repairman out to see.
