short weird red/blue lines on tv

[Sky_Powder]

So my t.v has this really weird thick red line on it that won't go away. I've applied pressure to it and it's still there, and I've also used a stuck pixels fixer software to see if the pixels where stuck. But now they don't seem to go away. The lines are red when it's behind a dark image, but when it's behind a lighter color image, the lines turn blue. Is there anything I can do on the inside of the t.v?

Don't post same question more than once!!!

There's little you can do, especially if you have never serviced modern TVs.
- it could be loose ribbon cable
- it could be bad solder joint
- it could be failed component (capacitor)

Depending on where you live, you might be able to find a repair technician to look at it, and either repair it, or recommend spare parts.
