I replaced the Video Main Board because the coaxial part of the tuner has been broken. The board Number was EXACTLY the same CV3393BH-A32 and the number on the sticker was exactly the same.

Its part of the tuner in most cases and not real easy to replace for a novice---sometimes the tuner will have to be replaced as when it broke off it may have damaged the circuit board inside the tuner.

there is a possible way around this: With a box of any kind being used that has the Audio/video jacks for output of signal you run cables from them to a set of matching inputs on the rear of set, leave set on that input and change channels with the box--bypass the tuner completely.

If the tuner and board it is only sold as a complete unit it will be expensive to repair.

If the board is not cracked,a qualified technician may be able to sloder another coaxial jack for a service call charge. Look carefully with a flash light........if you see the small board is cracked.....it will need the tuner and could cost $200. You may be able to cicuimvent by hooking your cable box or satellite box into the video inputs instead......select with input button on remote and should work fine with no repair at all

U have HDMI ports,order HD from the cable or telicom compannies.Use a HDMI cable for the tv,also get HD channels.Do not have HDMI ports than ur Main signal board must replaced the Antena analog coaxial it broken.Well not able to buy the coaxial input for the antena along for part.

With difficulty.
Soldered to board.
Only qualified techie can do it.

Hello sounds like the coaxial connector has come off or broken off the tuner, You can repair this problem using the old connector that broke off by taking out the tuner and resoldering the center pin back to the tuner board (provided the small tuner board is not cracked) and the out side of the connector to the tuner housing for ground. If you are just using or referring to a common coaxial cable to purchase, you can get these from everywhere Radio shack, Fry's etc. Also ur local cable company. If all else fails use the rca output jacks from the cable box if u have one and connect it to video input one on the back of the television, make sure you change you television input to video one if u decide to do it this way.

Sometimes you can replace the rf connector by resoldering it with a replacement rf. You will have to remove the tuner to do this. The big question is did you crack the tuner board or the board the tuner is connected to. You will really have to examine these. In most of my cases a successful replacement rf connector will fix.

If the connector end is not damaged and the tuner circuit board is not broken, you can solder this back onto tuner, and solder the end back on the circuit board. You should take the tuner out to do this proceedure. A TV shop usually charges $50.00 to do this.

These set are world famous for poor solder conection in there tuners, And since these tuners are part of the main board you have to remove the shiel and resolder them. A simple rule of thumb, resolder everthing in this shielded area

I assume that you pulled the F connector out of the back of the TV. In most Sharps, the F connector is attached directly to the tuner, which is the rectangular silver metal box soldered to the main PC board. Did you buy a replacement F connector or the entire tuner? Either way, the tuner must be unsoldered from the main board and the new F connector is soldered into the old tuner or the new tuner is soldered in its place. If you do not have experience soldering PC boards then let a qualified tech handle it for you.
