Question about RCA 35V432T 35" TV

1 Answer

Tuner Trouble No tuner input signal from the cable. Snowy - but traces of sound and pix. All other inputs work. Suspect Power surge during storm. Tuner likely not getting a proper voltage from the power supply. Anyone have experience with this? Set isn't old and a diagram is not listed anywhere at this time. Recommended sources are automated and I'm at a dead end. I can do this if I can locate a schematic. I need the diagram unless someone has already located a short zener and can point me toward it. There are dozens of sources for schematics - but no one has it available. Please don't suggest a source unless you know they have the diagram - I'm tired of beating the bushes - I give up. Thanks TVGUY

Re: Tuner Trouble

You will have to order this through an authoized RCA dealer Its not old enough yet for general publications from RCA If you call Sherl at TEEVEE Supply at 1-866-207-9824 or give them the CHASSIS number NOT the model and they will order you one. You should know my freind when dealing with RCA alsway go by a chassis number! Good Luck

No picture on main screen

Sets with PIP use two tuners--one for main and one for PIP---likely the main got hit with the static discharge during the storm----Here we always disconnect both power and cable when a storm.

There is a way around this (will lose PIP) with a cable box connected to the audio and video inputs on rear of set---bypass the tuners and use the box to change channels and provide signal.

let me know if questions.

Refer to the manual (free download here). Generally, a blue screen indicates a very low or non-existent signal. This can happen when the antenna is unable to gather enough of a signal from a particular broadcaster, or if an A/V input is selected, but the A/V device is not on or providing a signal. Since you are not seeing channel information when tuning, I suspect that the television is set to display an A/V input instead of the internal tuner.

With a working remote, locate the TV/AV button on the lower left (manual page 3 - item 8). When this button is pressed, you can choose to display signals on the ANT, VIDEO1, VIDEO2 or COMPONENT jacks. The ANT selection chooses the input on the RF jack such as an antenna or cable TV (with or without converter box). If using a cable box, the TV tuner should be set to Ch3 or Ch4 as determined by your cable box. Otherwise, select the VIDEO1, VIDEO2 or COMPONENT input that has the source signals you wish to watch from a cable box, DVD player, etc. that is connected to the rear input jacks. Page 7 of the manual details the connection and remote operation.

I hope this helps!

When i turn on the tv its norman picture but about 5minutes the picture will snowy what is the problem of that? tnx hope u help me

A snowy picture after warmup is either in the set or not.

What you may want to do to begin with is hook up a DVD player or something else to ONE OF THE VIDEO INPUTS ON BACK OF SET this will narrow it down to the tuner or the front end of the set.

If A/V hookup works you always have the option to hook the output of the cable or sat box to those same kind of rear connections- bypass the tuner and front end signal circuits completely.

As it only happens when on a short time not likely to be a hookup or bad connection there but check them anyway.

If using a box of some kind run the cable or sat direct without it--bypass the box to rule it out.

Last is if tuner in set is bad it would have to be removed and or rebuilt/replaced---not cheap parts and labor

I am having onida 21 ky thunder 800 tv.i am not getting clear picture is there any secret menu settings which can help me

You must apply a clean signal and see that the picture is clean if not the TV tuner section is faulty.
If there is snowy picture then the input RF section , the TUNER section and the VIF/SIF section must be checked.
There is not much in the menu than to use a fine tuning to have a clean picture.Otherwise the tuner is a suspect.

Tv getting snow & static sounds on all channels.

This TV, I believe, does not have a digital tuner. If you're trying to pick up channels off the air with rabbit ears or a rooftop antenna, you'll need a digital converter box. Without one, there aren't any channels for it to tune in, so all you'll get is snow and static.

If you have a converter, or are using this TV with a cable box, satellite receiver or a similar device, you may have a bad connecting cable. Be sure the cable is firmly connected and that the center pin isn't bent or too short for a good contact. It should extend an eighth of an or so past the end of the connector. Try another cable.

If this set has been working properly and the trouble is new, something is up with the tuner. It may have been damaged during a storm or from power line problems. Poor solder connections may have developed on the circuit board. Other electronic failures may have occurred. If the trouble appears to be inside the TV, it's probably not worth repairing. The replacement cost of a small TV would be not much more (if not even less!) than the labor and parts to fix it.

I hope this has helped. if so, please take a moment to give a thoughtful rating. Thanks for using Fixya!

I have a Toshiba cx35e70 tv. The problem began as a turn on, live screen, no channels, no sound. I found that when I would tap on the tuner on the main board the problem would disappear. Every thing worked...

Is the VCR going through ch 3 or video inputs - if video inputs your TV tuner is likely bad if through ch 3 seeif te picture goes funny on ch 3 without using the VCR the tuner may be bad on higher band channels - smetimes you can remove the tuner and resolder the tuner itself. But if it always works with the VCR just use it that way and don't bother with the fix.

JVC I Art No Sound


I would suspect that your tuner section in the television has developed a problem. Since the input sound is directly input into the tv's microprocessor, then the tuner is probably the culprit and should be replaced.

The tuner section is the shiny box-type section with the cable connector attached to it. I do not recommend trying to repair this set by yourself, though. The voltages inside the television can be lethal. Please refer this unit to a repair shop , as the repair should not be much. Or, you can use a VCR as the tuner to the television, using same input that you use for your dvd player, and use the VCR remote to change channels.
Hope this helps you...

Bad news. The tuner is bad. Instead of fixing the problem, you can hook up a vcr or dvd that has a tuner built in it. Hook it up to the video input and use the vcr or dvd to change channels. Or you can replace the tuner in the tv.

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.
