Hi


Thanks for using FixYa. It is either the T-con board in the unit has gone bad and/or it is not getting the required 12vdc from the power supply unit. If you have knowledge of internal circuitry of the unit then you can open the back of the unit and check the T-con board which is the last board before the LCD panel. Usually it is available with the LCD Panel. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

I have an older tv with only a coaxial cable connection on the back, no others. I have a Magnavox dvd/vcr combo that does have RCA connections available and also a coaxial cable connection on the back. I...


First make sure you have the cable connected properly.. on the vcr it should be connected to the OUT coaxial connector.

Second.. the VCR usually has a VCR/TV setting..

Most TV's must be set to channel 3 or channel 4 to output the signal from the VCR when getting the signal via Coax.

So..insert a tape...hit play..tune the tv to channel 3 if you are not getting the playback signal..press the VCR/TV button on the vcr or vcr remote.

Repeat this on Channel 4

Check your cable to make sure the connections are tight.

Finally check your television menus for Input settings..make sure it is set to COAX/ANT
Make sure your VCR's output is not on some alternate output like L1 or L2 (line one or line two)

Best of luck!

I have a 42 in LG HDTV and a dish satellite and a LG surround sound system how to I hook these up to hear sound while watching the sat


See if your satellite receiver has a digital out socket in the back ( optic / coaxial ). If so get yourself an optic/coaxial cable and link the TV out to your LG Home Theaters optic/coaxial In.
Now if your Satellite receiver does not have a digital out for sound you will have to connect the TV's audio out to the LG Home Theater Systems Aux / SAT / CBL input using appropriate cables .Either 3.5mm phono to 2RCA or 2 RCA to 2 RCA cables.

No movie picture


If you want to record from cable to your vcr the usual configuration is either cable to cable box, cable box to vcr, and vcr to tv. If you want to get rid of the snowy pictures, you can plug the cable box directly to the tv and separately to the vcr, and you can also plug the vcr into the tv. but the tv has to have two inputs
the best configuration will be the black, screw in, coaxial cable from the cable box to the television and the red, white and yellow RCA plugs from the cable box to the vcr in.
then the vcr our red whit and yellow cables to the back of the tv.
To watch vcr, switch the tv to video mode
to watch cable, switch tv to channel 3 or 4, depending on the cable service.
please let me know if you have questions.

Snowy picture


Hi,

A snowy video indicates that your input signal is relatively weak. On the other hand, a noisy picture is when there are too much interference is super imposing on the video.

Snowy picture comes about when the signal coming in the RF INput (Ant/Cable) at the back of the unit is below a certain level. If this is the case, then it is not a problem with your TV but rather your aerial (antenna) or the cable from your provider. A way to verify that it is the ant/cable that is the cause and not a defective TV/tuner is to hook up an old VCR set to Ch. 3 or 4 to the RF IN of your TV using a short 75 ohms coaxial cable terminated at both ends with FP-5 connector. Play a known clear good tape and set your TV to Ch. 3 or 4 as the case maybe. If the picture is relatively clearer, better, then you have just confirmed that it is indeed your aerial or your cable (provider) that needs looking into. If on the other hand, the VCR signal is also snowy then chances are that you have a problem with the input stage of your TV including possibly your tuner.

For your aerial problem, antenna orientation or replacing with a higher gain antenna might help solve the snowy signal. For your cable problem, you have to call-in for service from your cable provider. If it is a TV problem, your best course would be to seek the services of a qualified TV technician since this involve electronic circuitry analysis, diagnosis and possible component replacements.

Additionally, you may try looking for any loose connection, loose grounding, broken wire or anything out of the ordinary in your connections.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

How do we adjust our tv


You didn't mention anything about a cable box, VCR, etc. which might be connected. A snowy pic. means simply, inadequate signal is reaching the tuner, or the TV tuner itself is bad. If the first is so... check your cabling. If you have a VCR or DVD player hooked in between the cable box or outside antenna (whichever is the case), VCR (RF or ant.) out should go to the TV, VCR antenna (RF or ant.) input to the cable box. Also check the cable wire itself. If you look at the end of the cable, you should see a relatively thin center wire. This center conductor is what carries the signal. If it is missing, bent over, or too short to make contact with whatever it is connected to, you will have a very snowy pic. If you have a spare TV, connect it in place of your "new" TV, to narrow down the problem. Lastly, if all is well with hookup, cabling, etc. the TV might have a problem. Sometimes the tuner has a component defect, or the coaxial connector can be broken.

If you are on cable, first run the cable wire from the wall directly to the TV, eliminating any cable box and/or VCR. If channel 2 is snowy but the rest (especially 3-6) are clear, it is most certainly a cable problem and not a TV problem. The TV uses the exact same circuits for channel 2 to 6 (VHF-LOW) so if the tuner was bad and 2 was snowy, 3, 4, 5 and 6 would be snowy too. Bring a second TV into that room, disconnect the cable wire from the RCA and connect it to the second TV. Is channel 2 on the second TV as snowy as it was on the RCA?

No cable picture or sound


only thing I can think of is for you to check your cables... assuming you are using a coaxial cable for the satelite and rca cables for games and dvds, I would recommend trying a different coaxial cable. There is also the chance that the coaxial connection on the tv itself is messed up. you may try buying an RF modulator that will convert coaxial to rca, most rf modulators convert rca to coax. so make sure it does what you need before you buy it. tech guys at store should be able to help if you can't figure it out.

While watching tv, the tv all sudden goes snowy, no sound, and have to turn it off and back on to make it work again


Connect up another set right next to that set thats going out to make sure the cable or that line is not bad. It soukds as though you may have an intermittant tuner assembly inside the TV set. Its also a possablity that there could be a bad solder connectiuon in or around the tuner assembley. Not really a job for the user, as this set has hot and cold chassis, and can give a mean shock if you do not have the know how to work on these monsters. good Luck PS Please do not forget to rate this thread.
