Question about RCA F36450 36" TV

1 Answer

RCA F36450 TV is intermittently snowy

This tv is about 5 years old and recently developed snow. Thought it was the cable box or connections but all seem okay. Also tried different video inputs to the set and am still getting intermittent snow even with a different device than the cable box. By intermittent, I mean the picture goes clear for a few seconds and then gets "spots" of granularity that are big enough to call snow in my mind. It's not over the entire picture either but seems to move to different spots on the screen.

Re: RCA F36450 TV is intermittently snowy

Your tuner assembly has a bad connection inside of itself, or there is a bad connection around the tuner assy. if this is an ATC113 chassis Good Luck

I was watching my television and all of a sudden the picture went snowy.

Only the older Analog type televisions get snow from lack of signal. The modern Digital TV gets pixilated. like missing pieces.
And on re-reading the title of your question, it does say CRT...... As in Cathode Ray Tube. (I thought they were all gone now, all around the world) Anyhow.... has your country switched off it's analog tv transmissions. This would give you snow. Because there is no Transmission. Seems unlikely they would stop transmission in the middle of what your watching.
Do you have a Digital Set Top Box feeding the TV? This would pick up Digital TV transmissions and convert them to your old CRT TV Screen. Knowing this should help you diagnose the problem.
Check the antenna input to your digital box and connections from the STB to your TV. They probably use a Yellow video cable and a Red & White (Sound Left & Right). You didn't mention if sound was still there?
Perhaps someone has pressed the remote control and the TV has jumped to one of the Antenna Channel inputs rather than the Video input (Yellow Video input)?
Might be that Simple.....
Good Luck

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.

The remote control may only work for the cable box and you may have to manually put the TV on the correct input channel also you might double check that the cable to the TV is hooked to the antenna input. Here is the website for the manual TV if you think it might help.

1996 RCA Color TV model G27720tn

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?

RCA F27650 27" TV - Snow Bursts

The model you listed, F27650 uses the new ATC113 series chassis, which is only about 3 years old. The ATC113 chassis is not known to have snowy issues, but if yours is then I would suspect that a solder joint is loose in the tuner. If your set is actually around 9 years old, then it might perhaps have the notorious CTC175 - CTC187 series chassis, which went snowy all the time due to cracked solder joints on the shield grounds around the tuner and microprocessor. In either case, some good quality resoldering should cure your trouble. If you have never done fine solder work on PC boards with small surface-mount parts, allow a qualified tech to handle it for you.

Have cable.........but not working

The GE (actually RCA) 31GT659 has the notorious CTC187 chassis. This chassis developes cracks in the solder joints on the shields around the tuner and microprocessor, and can mess up the settings stored in the EPROM IC. This could result in channels going snowy, vertical collapse, loss of sound and/or total shut-down. The set should be resoldered and reprogrammed by someone experienced with this RCA chassis.
