Question about Sony KV-36XBR450 36" TV

1 Answer

Static & no picture from UHF input / Component Video fine

When I'm watching either cable TV or VCR, both of which come in through UHF cable input, I sometimes get static and lines across the screen. Other times, when watching cable TV, I'll get grey "noise" with "no signal" appearing on TV. However, I have no problems watching DVD, which is coming in through component video cables... perfect sound and perfect picture. Does anyone know what part needs to be replaced and how easy it is to replace it?

    A more accurate description of the problem is that there is crackling and loud popping, which is accompanied by white lines that appear horizontally across the screen. This is not accompanied by pixilation. There are time periods where it does not occur at all, and times when it occurs frequently. On other occasions, I turn on the television and get a grey "snowy" screen with no sound, and a notice that there is "no signal." Again, this only occurs for video/sound coming in via the UHF connection, and not via the component video connection.

How do I hook up my dvd/vcr to the tv


On the back of the cinavision you have two groups of sockets. The yellow socket under Video out is picture. Red and white is sound. Connect them to the TV's yellow red white sockets marked Video In 1. This connection will give you picture and sound from either the VCR or the DVD deck.

There's a better picture quality available for DVDs only from the Component video out sockets (green red blue). Next to them is another set of audio sockets (red white). Connect all five sockets to the TV's input number 2. The colours match up. The picture from Component will be clearer and sharper.

On your Sharp TV remote, select Video 1 to watch VCR, and Video 2 to watch DVDs.

Wil my tv work with out remote


There are quite a few ways to connect cable box, DVD, receiver and TV together. At a minimum---Connections between DVD and a/v receiver: For Audio, either digital coaxial, digital optical or simple RCA (CABLE ONE); If you did not use RCA you need to connect Video with either component or s-video (CABLE TWO). For connection between a/v receiver and TV: either component, s-video or RCA (CABLE THREE) You did not mention how your cable (or sattelite) box is connected. You could use same set-up as between DVD and a/v receiver for another one or two cables depending on set-up used.connecting the speaker wires of an RCA TV to an amplifier: The signal that is fed to the speakers is not designed to be fed to the line-level inputs of your amplifier. You'd need some kind of conversion and I can't tell you exactly what that would be.

Get some double-screened satellite cable and fit a female TV plug to it (or a male plug with an adapter). Connect it to RF Output 2 at the rear of your Digibox. Fit a TV plug to the other end and plug it into your TV.

Temporarily disconnect the aerial feed from the Digibox aerial socket. Switch the Digibox on to get a picture on your main TV. The Sky Digibox normally sends its signal out on UHF channel 68 so go to the second TV and tune it to 68 (or tune it till it finds the Sky picture).

Now plug the aerial cable back into the Digibox. If there is now interference on the Sky picture on the second TV (or on the terrestrial channels) your Sky signal on 68 is causing interference. Press [services] 401 [select]* and set the RF output to a different UHF channel number. You need to connect it via a Scart lead on your main TV in order to see the menu.

*In the new EPG (April 2009) it's [services] 001 [select]

Try each RF output channel number in turn (21 - 69) and retune the second TV until you get clean pictures on the terrestrial channels and the Sky channel. Also check the picture from the VCR (if connected).

This is just a brief overview. If you need a real in-depth explanation you should read the "Piping TV Around the House" Ebook by satcure.

With Direct TV, you should use the video input (composite video- yellow/picture, red/right stereo, white/left stereo)
OR
component video- (green/video, blue/video,red/video white/left channel stereo, red/right channel stereo)

the antenna connector should never be used anymore unless connecting an outdoor antenna or VCR.

if one of your input connectors is damaged, it is not likely that is will be repaired without replacing the entire circuit board (expensive!!!).
just use a different "input"- there are usually at least 3 on most TV's

Hi,
Problem seems with main tuner in this tv as other AV inputs working fine so please replace main tuner (TU2) to solve this issue.
There are two tuners mounted on A board TU1 and TU2, please replace TU2 and part number would be written on tuner itself.
TV is approx 10 years old so I would recommend that do not spend lots of money on it.
Thanks.

Multiple video inputs


Unfortunately, you cannot use the connectors at the same time. The S-Video connector overrides the standard video connector. This is why they share common audio left/right inputs. If you could use them separately, they would each have their own set of audio inputs. (S-Video does not carry audio signals on the cable.) I'm assuming that you are connecting your Satellite as an input to your VCR, and then your VCR to the TV via a video connection. The VCR passes the satellite signal through unless you are watching a tape, then it overrides the dish signal. You have a few choices here: 1. You can connect the coaxial (RF) output from the VCR to the TV, and watch the satellite and VCR on channel 3 (or 4). You can then connect the DVD via S-Video, and watch it on "video". This is the simplest solution, and provides the best picture quality for the DVD (with this TV), but lower quality for the dish and VCR. 2. You can connect the DVD player via RF (if it supports that), watch the DVD on channel 3, and connect the VCR via video. This will make the DVD picture quality terrible. 3. You can replace the VCR with a combo DVD/VCR unit. You can then connect the S-Video out from the combo unit to the TV. This is a more expensive solution. 4. You can replace the TV with a model that includes more inputs. This is the most expensive solution, but will allow you to watch your DVD over component cables (very high quality) and VCR and dish over S-Video. Ironically, the obvious choice, connecting the DVD as an input to the VCR (as a pass-through) simply WON'T WORK. The signal put out by the DVD player is "copy protected" (using a system called MacroVision) which the VCR will refuse to play, even as a pass-though. Best of luck with this. Given that you are trying to make this all work without replacing equipment, I recommend option #1, until you decide to break down and buy a shiny new HDTV. They are coming down in price every week, but only you can decide when the time is right.
