If you consider yourself mechanically inclined, and have some experience in soldering, In most cases,this is really not too big of a deal. If you are not that handy, dont mess with it! Youll thank yourself later. To proceed: 1.) Remove back cover. (make sure no children or pets are in your work area) HIGH VOLTAGE!!! 2.) Be aware of high voltage transformers. They are "live" even after being un plugged! 4.) Locate the Tuner (metal box in which connector was attached to) The "lid" on the box also serves as the ground for your F- Connector. Remember: outer part of conn. is ground. inner part is your signal. Survey the tuner to make sure it is not too damaged. If circuit board inside of tuner is broken or cracked, it may need to be replaced. Usually, the conn. is simply torn from its moorings and needs to be re-soldered. 5.) Always "tin" your parts first. clean and flux parts to be soldered. tin your work. Find some way to hold parts steady while solder cools. Bare hands are not a good idea. Parts get very hot....very fast...Determine how you will connect your center conductor first. Once that is done, the outside ring is a snap. Remember, Tip and ring ? If any of these terms do not sound familiar, you probably dont want to fix yourself. Good luck.....Theroad

This problem is for people who know how to do soldering. Just buy a new connector , it cost $0.50 and $15 for labor if your technician is good . it ask some expertise, because you have to remove the tuner open the tuner and make the soldering by putting the new part.

Good luck.

I have a Panasonic TH-42PX600U and the RF board displays a red light and the screen says no channel found. Can I change the board myself, does it just snap into place

if you have the right tools then you can do it, make sure unplug the tv unit first while replacing the board. then mark or put a label to the connector that you were disconnect not to interchange that can cause of damage to the other board.

The cable connector has been broken off. is there any way of fixing this without replacing the entire board

With most tv's I've serviced, the cable connector is connected directly to the tuner module. The tuner module may be damaged beyond repair, depending upon how much physical force was applied to the cable connector. I would take it to a reputable repair shop and let them provide you a honest estimate of repair. They may be able to resolder the cable connector to the tuner module.

That is what the service provider would do if you took the television in to be repaired. The service provider would attempt to solder the rf connector back to the television or solder a new rf connector to the television.

Yes, you have a bad ground on your RF connector. With lots of patience, it can be repaired. You must remove the tuner shields from the TV. It will need to be unsoldered. Pull the shields off either side of the tuner. Donot even attempt to move the red coils you see in the tuner. If the red coils look bent or smashed it is for good reason. Do not bend or move these. I cannot say enough about these. Next you will solder the Rf connector and the tail that is is still connected to the tuner board. Inspect all the solder connections on the solder side of this tuner on board.There are about twenty bad grounds. You will have to really concentrate and excercise great caution to solder. Be careful not to burn any traces on the tuner board. Patience is a virtue here, any mistake may destroy your TV. After careful inspection and soldering you may resolder the tuner shields. If you feel you must replace the Rf connector that part is an RCA #215543. Remember it will take more than replacing this connector, to fix the snow you receive on the TV. Thanks for asking and show a few hands of support.

RF connector broke from board....looks like part number is 1519592K, but nothing appears when I enter that part number..how do I get new board?

Hi,

You can't buy the RF connector parts from a TV component supplier as they are already soldered to the main board. A friend who can solder PCBs or a TV repair shop should be able to re-solder the original for you. If it's damaged, a TV repair shop might also be able to find another that will fit as they are fairly standard components. This will be far cheaper than buying a new main board and it's probably going to be difficult to get one.

I had a look for a new main board, but the TV is fairly old and I couldn't find one or a part number. It's easier to find components by part number rather than by TV model, so your best bet is to find the part number on the main board and try searching for that on Google or similar.

If you want to post back with the model number, I don't mind having a search for a replacement main board, but my advice would be to get the existing repaired, if possible.

Hope this helps.

Regards,
BElectric

Problem for Sylvania LC195SLX LCD TV Channels will not program in tv.check with different tv it works

It looks like your TV doesn't have a digital tuner in it. Without that you won't be able to receive any broadcast television stations. The spec sheet is here: LC195SLX the tuner is listed as just ATSC/NTSC - not digital. You will need a cable or satellite box to receive stations.

I have a 36 in Toshiba 2003 TV, model # 36A43. The cable connector on the back of the TV snapped off, Is there an easy fix? Can I buy another part? Any suggestions?

There is really no easy fix...but patience is on your side if you have some. You will need to buy an RF connector at a electronics store..Please visit a commercial dealer, Radio Shack is to limited! Pull the tuner out of the tv board, open the cover that contains the solders. Lets hope the board is not cracked. and be sure one of those small coils are not pulled out..Donot even think about touching or moving these coils if you open the wrong side ot the tuner shield. Reconnect the tail of the RF connector through the board. You sometimes will have to cut the tail length wise for a fit. [You better buy two RF conectors just incase you make a goof. Then solder the a ring around the RF connector to the tuner box. Reinstall into the tv board! Hope this works!

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.

I have Samsung A550 46 LCD HDTV, and Anteina IN Broken

Yes it can be fixed if the tuner board was not damaged. Get an RF modulator, you can pick them up at walmart, and use your RCA inputs in the back. All you do is input your main tv cable into the RF mod cable in, then connect to the out of it with your RCA cables and then into the RCA connect in, into the back of your tv. Or, like you said, you can input your main tv cable into your vcr/dvd then come out of that with the RCA cables, and again into the RCA cable in on your tv. This way you have to syncronize your channels after you do this to get the picture. You know, vcr on channel 3 while your tv is set to input 1 or whatever needs to be done.
