Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

You're discussing about the input socket [Ariel socket] to your TV is broken; I assume, and posts this solution. In most cases, this is a irreparable fault; because, this socket is directly connected to the tuner, and is a part of tuner body [case]. If it is broken, the the tuner should be replaced with an identical one. You should check out the number of the tuner used with your TV; can be noted on it by a sticker. Just buy that number tuner, and replace it. The tuner can be bought from most of the electronic spare part selling shops.

A white horizontal line on a tv is an indication that your vertical circuit is defective. Very common for the vertical IC to go bad. The fuse in a TV set is only there to keep your house from burning down if there is a problem. Your set has a problem. In my area repair should cost you about 100 to 120$. Tube Tv sets have about 5 years of expected life. I would invest my money in a new LED set.
I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV(warranty was expired ofcourse) and found four bulged capacitors. Many electronic companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices.
Here are some options .
1. 1.Have it fixed by a professional
2.2.Dig into your TV, find PSB, Check for faultycaps. If you find some(bulged orleaking) bad caps replace the entire board
3.3.Remove and then replace individual faultycaps. This takes some solderingskill.
Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
Hope this helps
OK. IF THE RED COLUR HAS GONE, YOU PROBABLY NEED TO CALL AN EXPERT. LIKE I TOLD SOMEONE ELSE, IF YOU USE A CABLE BOX, ITS PROBABLY THE CABLE BOX. ALL YOU NEED TO DO IS HAVE THEM LOOK AT YOUR TV AND YOUR CABLE BOX IF YOU HAVE ONE, AND/OR BUY A NEW TV AND/OR CABLE BOX.
