Question about Recoton Advent Advent HT3251A TV

1 Answer

Advent HT2751A display no good until after 1-2 hour warmup - maybe

All inputs, will not display video, although the audio does come through. When in RF/TV channel mode, the screen shows a picture with lots of horizontal tearing. Eventually it just displays a random, static spotty colored picture. After a good hour or two, the set may actually begin working - although the picture quality is not perfect by any means. What info I've gathered suggests it's power supply/flyback related. It's strange that heat actually helps the set begin working correctly. I believe the problem to be more related to a bad IC than a power problem. From what info I've obtained, this problem is not unique. I have to believe someone out there has faced and fixed this problem.

    OK - I entered this problem and now for closure I will add the following repair info. I took it to the only place in town that would repair it. It turned out to be a bad capacitor. I don't know which one, but I do have the bad part. If you're curious, this repair cost $103 and the TV now works great. Since the set cost $300 plus, I figure it was worth having it fixed - this time...

    When I first turn on the tv, it will only display the blue screen. After turning the tv on and off a few times, the sound may come on without a picture. The tv eventually comes on with picture and sound. Just yesterday, I noticed that the picture on the screen is bowed on the sides. The screen appears to be taking on a hour glass shape. I will like to see what this capacitor looks like. Maybe this is the problem I'm having

    I have a problem with my Advent HT2751A very much related to yours. When I leave the TV set on the Picture is scrambled and when i leave it on for 30 mins the picture comes back slowly but after 45mins of warming up, i turn the tv off and on and the picture comes back but it'll distort again 2 hours later. I would like to see what the capacitor looks like if you have a picture of it.. I posted pictures of my Symtoms.


    When i first turn on the TV:

    After the TV warms up:

    Picture stays frozen like that for like 45 more mins..

    AFTER the tv warms up for an Hour, i turn it off then on and it works for 2 hours then it repeats the cycle:

After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.

Testimonial: "We took it to a repair shop and that exactly what they did - replaced 1 capacitor. Glad you figured it out. Thanks!"

I'm trying to figure out how to connect an apex digital t.v. converter box to a hitachi clu-5722tsi television...how do I do this? please help!! picture is the back of the tv..but then I also don't know...


Most digital converters provide two types of output: an RF output that connects to the antenna input of your TV and left audio, right audio, and video outputs that connect to the corresponding inputs of your TV. The RF output connection produces a digital picture on channel 3 or 4 (selected by you at the converter) with your TV set to the appropriate channel. The L/R audio and video connection produces a better quality picture. Choose one or the other, but not both. The picture you provided shows three possible inputs for the L/R audio plus video arrangement.

RF Modulators and cable connections


948bde9.jpg

RF MODULATOR HOOKUP
For a TV with only a RF input jack, a RF Modulator can be used to hookup DVD players, DVD recorders and other devices which output RCA composite video and audio. For example, analog cable TV can be connected using a RG-6 type coaxial cable to a VCR or older DVD recorder's analog cable ready tuner RF input. Then as shown above, the output can be connected to the TV thru the RF modulator. The modulator outputs on channel 3 or 4 for the older TV so the TV is set to channel 3 or 4. Some RF modulators are built-in to Audio/Video switch boxes. These allow multiple RCA inputs along with RF input.

RF MODULATOR CLOSE-UP
The modulator converts signals to channel 3 or 4 so older TVs can tune them on their analog tuners channel 3 or 4.

I found a SuperNintendo that has been in our attic for many years, however when I conect it upo my TV cannot find the output from the SuperNintendo when it does a search. What frequency or channel does it...


Locate the TV's VHF IN [ANT, CATV, or 75(ohm)] or Cable Connector.
Disconnect the existing cable wire from the TV's VHF IN.
Connect the short, thick wire from the RF Switch (labeled ANT) to your TV's VHF IN.
Reconnect the existing cable wire (disconnected in step 2) to the silver post labeled ANT on the RF switch.
Connect the thin wire of the RF Switch (labeled Control Deck) to the back of the Super NES (labled RF Out).
On the back of the Super NES, set the 3/4 switch so that it matches the channel of the TV.
Note: The RF Switch does not produce stereo sound. To get stereo sound, connect your Control Deck to your TV or VCR using the Stereo Audio/Video Cable.

After the system is connected to the TV:

Insert the Game Pak firmly into the Control Deck.
Plug the controller(s) into the front of the Control Deck. Use the far left port for a one player game.
Plug the AC Adapter into the back of the Control Deck. Plug the other end of the cord into a wall outlet.
Slide the Power Switch to the On position.
Turn on the TV and set it to the appropriate channel (3 or 4.)
The game image should now be displayed on the TV screen. You are ready to play!
If after following these directions you are not able to view the game, try our Troubleshooting Tips. Note: pictured above is the redesigned Super NES. The original Super NES uses the same hookup steps listed below.

Installation Steps:

Locate the Audio/Video inputs on the back of the TV.
Place the yellow end of the Stereo AV cable into the Video "in" on the back of the TV. Connect the red end of the cable to Audio "in" Right. Connect the white end of the cable to the Audio "in" Left. Use a slight twisting motion when inserting each cable and ensure the cables are firmly pressed into the input.
Note: If you have a mono television with only one Audio input, click here for a diagram of how the hook-up will look. The Y-adapter pictured is optional; you can also simply leave the white cable disconnected instead.

Connect the rectangular (gray) plug of the Stereo AV cable into the "multi out" connector on the back of the Control Deck.
After the system is connected to the TV:

Insert the Game Pak firmly into the Control Deck.
Plug the Controller(s) into the front of the system. Use the far left port for player one.
Plug the AC Adapter into the back of the system . Plug the other end into a wall outlet.
Slide the Power Switch on (toward Game Pak).
Turn on the TV and locate the input select. It is often called: input select, AUX (auxiliary), Line, Line In, Input, Source, Select, In, or EXT (external). Switch the input select to show the Nintendo game.
The game image should now be displayed on the screen. You are ready to play!

I have audio and the set displays the channel number/ sound and menus. However it will not show the image that is playing on the tv


Your TV has video problems. Input any video signal, from dish or from DVD player or any other source, after setting the TV to video mode. If there is video, fault may be in the RF video output section, which could be detected through through checking. If DVD video also in not there, the problem is of video swiching [usually electronic changeover inside the TV]. Which can be rectified through a technician.

Can't get anything to show on TV screen..No menu or anything..


I'm still confused. Walmart has this with pictures. This DVD player has regular RF Coaxial TV output and input. But, the best way to connect it would be Video Out and Audio Out for the connection from the DVD Player to the TV. I guess it has a tuner in it? or else why would it have a TV input on a DVD player?

Specifically the Pr, Pb, and Y connectors and the Red and White - Left and Right Audio Out connectors.

That would give you the best audio and video to most modern TV for last couple of years. (I don't see HDMI but that would be even better if it had that.)

So does your TV not have Component Video (Pr Pb Y) inputs? And Audio Left/Right inputs?

If not then you are connecting Coaxial Cable RF input to your tv? The TV would have to be in TV mode in this case and on the correct channel ... I would imagin Channel 3 or 4 of the old NTSC style TV channels. Most TV's still do those - even with the new Digital TV channels being active.

I would like to know if I can connect a HDMI cable from My tv model WS-65315 to a Direct TV HD receiver?


NO> If your TV supports and have HDMI connections and your HD receiver has an HDMI output then you should have no problem displaying Video. Just make sure you change the input signal of your television to HDMI input. After looking at the spec's of this model these are the following inputs you have. your best picture quaity would be to use componet cables instead, which can show full screen 1080i format, your television does not show at 1080p whis is what HDMI is known for.
Connectors
Rear Input Connectors S-Video x 2 - Component x 3 - Composite x 2 - DVI x 1 - RF x 2 - 1 x RS-232C - Audio (RCA) x 6

Front Input Connectors S-Video x 1 - Composite x 1 - Audio (RCA) x 1

Rear Output Connectors Composite x 1 - Audio (RCA) x 1 - RF x 1

Another good option is use to use a DVI to HMDI connector and hook it up this way. But note: you will have to use audio cables for the DVI input.

Panasonic DMR-HS2 RF out is not outputting signal CH3 CH4 off


The most likely cause of this is the unit being in progressive scan mode. In progressive mode, the composite output is disabled. If you can, connect the DVD using the component output connections. If your TV does not have component input, connect the green connector to the yellow on the TV. If the unit is in porgressive scan, you will see a garbled picture on the screen. The only way to fix this is to turn off progressive scan. The manual will tell you how to do this.

Need instruction to hook up dvd player


You will need a TV or monitor with audio/visual inputs. The better ones have what is known as an S/VHS input, which separates the TV picture signal for better color reproduction. You will need to be able to switch your TV, usually by the channel selector, to the proper input for audio visual signals. Sometimes this is known as Video 1, Video 2, A/V etc. These are usually below Channel 2. Maybe your remote has that option. You will need an a/v cable. This is a three-connector cable with RCA plugs on each end. Connect the DVD player to the TV as follows: 1. Yellow cable, from video OUT on the DVD player, to video IN on the TV. Video is ALWAYS yellow. 2. Red and white cables from audio OUT on the DVD player to audio IN on the TV. 3. If you have S/VHS capability, buy an S/VHS patch cable which will have the three plugs mentioned, plus a round 4-pin plug. Select S/VHS OUT on the DVD player, and S/VHS IN on the TV. When using S/VHS, ignore the yellow connector. It is for composite video and not needed. Here's a hint: Your YV audio/visual inputs will usually be on the back of the set. Some better units have a/v inputs in front. What if my TV doesn't have a/v inputs? If your DVD player as an RF output, connect an RF "f" cable from that output to the antenna in cable on your TV. Otherwise buy an RF converter (about $20 or so at Radio Shack). Connect your a/v cable (yellow, red and white) from the DVD player to toe converter, then connect an RF cable (like the kind your cable box is connected with) to the antenna input on your TV. This signal usually comes in on Channel 3. Let me know if your problem is more complicated, It seems like a lot of wires and connections, but it is really straightforward, Remember, yellow is ALWAYS video. The two audio cables can be connected without worrying about color.
