Do you replace same value? Maybe you check other parts that had leak or high resistance, you may trace the primary supply and secondary. Check your flyback, mostly check all capacitor.

Most tv's have a way to turn off the speakers. Either a button on the remote, or in the menu. Go into the menu, sound options. See if it says speakers on/off.

I do not believe there is any easy fix to this. The problem may be either in the picture tube or the related circuitry. The worst case scenario is the tube itself is failing. However, it could be as simple as a defective connection on the pc board at the tube for example. You may want to get a technician to check it out and get an estimate before you buy a new set. Good luck

I too had the same problem where my HT30744 TV would lose its color. My mom's HT32744 would have the same problem too. They both are refurbished models bought at Value City Dept store. If I gave the cabinet a good hit it would mostly fix the color, but it could also make the picture go fuzzy too, a clear sign of just a loose connection somewhere.
So after my wife telling me she was sick of this almost 2 year problem and she was going to buy a new TV on the weekend, I figured I had nothing to lose. So I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.
