The Cable Connector in the back of my TV is loose.
The connector is connected to the tuner with soldier, when this breaks from mechanical stress, you get the symtoms you described. This is an easy fix. You will need a fairly high wattage soldiering gun, and some medium electrical soldier. This will run you around $30 at Radio Hut. You will need a gun that will do ground straps so dont get one that is under 80W. 100-150 watts is good. Actually you should get some good rosin flux too. The chromium or molydenium in those connectors can make them hard to soldier.
Soldier them hot and fast. Lightly clamp the male jack to the tuner. Tightly, you need good thermal flow. brush on your flux. ALWAYS Heat your gun FIRST. Til it gets good and hot. Flux, and tin the tip of the soldiering gun too. put the tip of the gun closest to where the two parts meet so you are heating both parts. When the parts are hot feed the soldier onto the hot parts NOT the soldiering tip!
You must do this VERY quickly. As in 3-7 sec to heat the parts, and push the soldier in as fast as it will melt, then get the gun back. Another note, if your soldiering tip isnt 'wet' with soldier you wont get thermal transfer. Also, if you fail to soldier try once more, but the internals (plastic) of the male jack will melt if you overheat, So cool it down somehow if you fail to get a good soldier, or just walk away for awhile.
These can be troublesome to soldier. Practice with you new gun on something else to get a feel for it. If you want to simulate the problem, take a coax coupler, and try to soldier it to a piece of sheet metal. Hope this helps!
