Question about Konka K1938U 19" TV

How do you replace the capacitor that receives the end of the cable wire?

My son, in his haste to disconnect the cable wire from the back of the TV set, pulled too hard on the cord (versus unscrewing it) and damaged the capacitor (the little metal box) that the cable wire screws onto. As such, I need to replace that capacitor, or little metal box that has the male connection that receives the female end of the co-axial cable. I cannot find the part itself anywhere on the web. The part number taken from the back of the part is: CRCR24MDCapacitor. Is this part evene available? IF so, is this the type of repair a novice can do? I would guess I need a soldering iron, correct? If this is over my head, what would it cost to fix. This was a $119 TV 3 years ago and so I don't want to spend too much to fix. Thanks, Mark

Mark, The only thing I can suggest is try to mend it yourself. Unlpug the TV from the mains etc. and remove the back. You should be safe in this area of the inside as it is usually far from the high voltages. (Keep your son away!). Locate the box and if necessary, prise off the lid which is held by springy sides. Try to fit the parts together again; you may need a soldering iron. Be careful not to short anything with the solder, put paper under where you are soldering. You may need a hotter iron as latest sets should use non lead solder. If you cannot repair it why not use the scart or Video (YellowPlug) inputs, ie as a monitor. Good Luck.

If that connector is supose to be connected to the tuner, a long rectangular box, then most likly the tuner will need to be replace, and on a set like this I looked up a rebuilt tuner and the cost will be 58.00 from PTScorp, but is not for a novice to do.. it should be done by a pro so therefor its probably not worth fixing. If its part of a small square box that a wire attaches to the tuner. that part should be available and is know as an antenna block assy. This should be no problem for you to fix.. good Luck ps please dont forget to rate this thread

Just a word of caution; the voltages & currents stored in a Television set are enough to kill you!! No joke.

I have Dish Sattelite. The screen on my JVC digital tv says digital strength is low. Do I call Dish? or ?

This sounds like a cable issue. Assuming your Dish receiver is connected to your TV with a HDMI cable (ends are rectangular and the connector is trapezoid in shape), you can first attempt to switch HDMI ports on the back of your TV. If you get the same message, you can try flip the cable end for end -- plug the TV end into the receiver and the receiver end into the TV (I know, sounds silly, but has worked for me). Next is a new (better -- don't get a $5 cable, most good HDMI cables start close to $20 and up depending on length).

Now if you happen to be connecting via a "standard" TV cable (RG 6), first make sure that the cable is screwed on snuggly (no wrench needed, just finger tight). Next is to get a new cable.

Try this steps
On the backside of your satellite receiver, you will notice a bunch of connections. If you already have your coaxial satellite cable connected to the INPUT on the receiver, leave it connected. Disconnect and remove the cable connecting the receiver to the television.
Grab your A/V composite wires and insert them into the Audio/Video OUTPUTS on the back of the satellite receiver. These are color-coded connections--red to red, white to white and yellow to yellow. The red and white connections are your audio feeds and the yellow is for your video.
Look on the backside of your DVD/VCR dual recorder. You will see similar connections. Connect the other end of the composite wires to the Audio/Video INPUTS on the DVD/VCR dual recorder.
With a second set of A/V composite wires, connect one end to the DVD/VCR dual recorder's A/V OUTPUT and the other end to the television's A/V INPUT. Again, be sure to follow the color code. Also, if your television has more than one available input, be sure to know to which one you made the connections (A/V 1, A/V 2, etc.)

Next, tune your television to the proper input channel. Look on the television's remote control for a button that is labeled "Inputs" or "A/V." Press it until you see the correct A/V channel appear on the screen. If you made your connections in A/V 1, then the TV should display "A/V 1" in the corner
Now, just turn your equipment on and settle back to watch your favorite show or DVD

Connected the coaxial cable to the tv but got no channels. the tv turns on but all I have is snow

Some possible things to check:

1. Are you trying to receive off-the-air broadcasting? If so, you'll need a digital converter box. This set doesn't have a digital tuner, so there won't be any channels for it to receive without the converter.

2. Are you connecting a cable from a cable converter box, satellite receiver or FiOS set-top box? Your TV will need to be set to channel 3 or 4 to see the signal from the device.

3. Make sure the center wire in the plug on the end of the cable isn't bent over, and that it extends far enough (about 1/8 to 1/4-inch) to make a good connection.

4. Do you know for sure that the cable you are connecting is working? Is there actually a signal on the cable? It may be disconnected somewhere else (at a splitter, for instance) or there may not be any signal source.

5. Have you tried another TV to test the cable? If the cable works with another set, the tuner or antenna connector on the snowy set may be bad. If the cable connector is tightened too much when hooking it to the TV, the connector may be damaged and this can cause the snow.

Start by checking with a known good TV. If that one is snowy, you can check the other possibilities. If it works, you'll know the problem is in your set and can decide what to do (repair or replace).

Hope this helps! Thanks for using Fixya.

Please take this disk capacitor to a commercial electronics store. For example an authorized TV shop, A general electronic supply or an NTE Supply reference catalog.

The plug to the tv broke off!

One way would be to go to a store that sells electrical parts and buy a replacement plug and install it.
The other would be to replace the whole cord, much more time consuming and probably a bit more expensive. I'd just go and buy a new plug.

Buzzing in television

Sounds like power supply buzz. Usually means dried- out electrolytics, U need a serviceman. Could be frame buzz, but I think unlikely.

Nothing but snow

Your explanation about a different TV receiver working OK on the same aerial connections leads me to believe you have lost the tuning in the faulty receiver...
Just "snow" with no sound is a classic response for lost tuning....
It shouldnt have lost the tuning as there is a small battery(capacitor) that holds the previous receiver channel settings when you turn the TV off. But as you have had the Receiver in the back of a truck and disconnected from the power supply for some time then this is probably the culprit....
This battery (Capacitor) may be getting old and has lost its capability of sending a minute amount of current to the tuner IC (Chip) hold your previous channel settings...So if you can retune the receiver to the output from the Dish Network Receiver you should be fine again, but if the battery is shot you need a new one....or just leave the Receiver in the standby mode for a couple of days to re-charge the battery (capacitor) up.
You will need a service technician to replace this small battery (capacitor) its a special type made just for your receiver....
Hope this helps

Sanyo DS25390 Cable Terminal Ripped off

I personaly would replace the entire unit, the capacitor is a Ceramic "DC Blocking/Couplng" capacitor, possibly a 0.001uF cap... I should think if ya take it to any component supplier/radio repair shop or the like they would be able to give ya a replacement?
