Question about Sharp 27N-S50 27" TV

Missing Cable Connector

I have a Sharp 27N-S50 and it is missing the cable (f-connector) connector on the back. I removed the cabinet and the shields where it enters the chassis, but don't see where I should connect the generic replacement part. I am an electronic technician (motorola) so I am comfortable with doing repairs. It appears to me the internal connection may have been a compression or some such fitment rather than being soldered. Any suggestions? Thanks,

    To be a little more clear, what I need to know is where on the tuner does the center pin of the female f connector connect to the tuner. Hope this clarifies things. Thanks again.

After you remove the tuner from the main board and remove the 2 covers from the tuner, straighten the metal side of the tuner where the hole is for the F connector. If you look at the PC board inside the tuner, there is a small hole in the board directly under the hole in the metal for the F connector. Usually there is a small piece of the old F connector's center pin still soldered in that hole. If it is there, unsolder it and throw it away. The new F connector will be soldered in place over the hole in the side and a small jumper wire soldered from the center pin of the new F connector to the little hole in the PC board directly under it. Be careful when soldering on the tuner's PC board because the parts are extremely small and close together, and lost SM parts and solder bridges are possible. Be sure none of the coils in that area have been squashed over, which is what I usually see when the costomer sticks something in the hole left in the tuner. If the coils are squashed, you can straighten them with a small pair of tweezers or remove them and rewind then around the proper size drill bit. Let me know how you make out.

How to hook up headphones to a sharp 27ns100


It looks like your TV has stereo AUDIO OUT jacks on the rear panel (L and R) which you can use to connect headphones. Go to a local Radio Shack or other electronics retailer and ask for help with the required adapter cable and connectors. They should be able to direct you to the product(s) as Radio Shack has these simple adapters and they should cost very little. All you need is a simple RCA cable with the white and red plugs for the TV side and depending on your headphones, either a 3.5mm or larger connector for hookup on the headphone side. They also sell extension cables so you can move away from the TV more. Don't let them sell you anything fancy or expensive as this is really simple.

The antenna/cable connector looks broken. can this be replaced?


Hello
In most models of Sharp Telivisions,antena socket is an integrated part of the tuner itself and cannot be replaced with an other one. There is only one way and is to replace the tuner itself.
If you don't mind of style, you can solder two wires, one from the center pole of the antenna socket, and other from it outer rim, and take it out and connect to an external ariel socket [can be bought from electronic sparepart shop as a seperate socket] , to whcih you can connect your ariel pin. It will look a little dull, but you can face the probelm, without replacing the tuner. When making these connections, use sigle cored shield wire. It center wire must connect to the center pole of the broken tuner socket. OK.

Coaxial hookup broke off. Can i use an s cable through vcr? need instructions.


If your Sharp television has RCA jacks, you may use them through your VCR. Your VCR would have to have a tuner and then you may use this as a means for getting a signal. Newer VCRs and DVD players generally do not have a tuner. Thanks for asking!

Cable hookup broken


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.

Watching DVD or VHS ...


I could not find the manual for your TV, but I did find one for model number 27N-S50 so hopefully they're very similar. If you DVD/VCR is connected to your TV with composite cables (the RED, WHITE, YELLOW cable set) then you need to change the input mode. There should be a button labeled Input on your remote and pressing it will cycle between the various inputs (Cable, Input1, Input2). I would guess your DVD/VCR is connected to Input 1. If you have lost the remote you should be able to get to the other inputs by using the channel selector button. Tune the TV to either the highest or lowest channel in memory and then press either the CH UP or CH DOWN button on the TV to cycle through the various inputs.

The other thing you should know is that there is a recall on this TV related to the power button. I discovered this while looking for the manual on the Sharp website. Go to this website:

http://www.sharpusa.com/products/support/0,2309,,00.html

Type 27R-S50 in the model box and select Television/Home Theater Projectors in the Product box then click on Get Results and you'll get information on the recall.

Also, if the info I've given about how to select the input does not work, there are links on the above site to help you get the correct manual.

Lastly, I don't get paid for this. I know it's a strange hobby, but I like to help out when I can. I hope you'll take a moment and give a prositive rating if this information has been helpful to you. Nearly half of the solutions I've posted have never been rated. Thanks and good luck.
