I need your help L42WD22 unsuable signal

You have posted this solution and I have the same problem

If the TV will play a HD input then the digital board can usually be repaired by replacing the fuse on the board. It's not a normal fuse and there is a updated part available so it won't go again. Any RCA authorized service center should be seeing many of these and should be able to take care of it.


I have opened the back cover of the tv and also opened the metal cover of the junction/connection box...don't know what it's called the one that has the shielded rf tuner.

Know I'd like to fix my own problem but the thing is that I don't know where the digital board is situated at and what fuse people are talking about.

I have some experence with electronics so I figure I can fix this myself with a little bit of help from generous people.

Thanks.

Mike from Montreal, Canada.

    I have the RCA L42WD22. The "Unusable Signal" popped up a few days ago. QWERTY957's solution was dead on. It was indeed the fuse. Replace it with an F1455CT-ND which can be found at
    http://search.digikey.com/scripts/DkSear....




    The cost from Digikey was $0.81 for the fuse. I bought 5 (just in case) and the total cost was $6.66 which included shipping and tax. It took a couple of days to receive the fuses and about 30 minutes to put the new fuse in, put it all back together and back on the wall. I did find it easier to just piggyback the new fuse onto the old the one. The tip on my home soldering iron wasn't quite small enough to get between the other components.



    Thanks for the help.

The part number is 275819. It is located near the tuner and has the location 7C32 on the board next to it. You may want to get the part then you can see what it looks like to make it easier to find on the board.

I have a Toshiba older TV that doesn't have HD digital converter box I bought a leaf ultimate antenna do I still need to use the converter box with this new antenna


if the tv does not have a built in hd digital tuner you need a Hd digital converter to analogue converter. What you need to be careful about is the available inputs on the TV if it only has AV in then you need a converter that transmits out RCA video or an analogue tv channel on RF the tv can tune into. Some of the new converters have HDMI out so if TV does not have HDMI input it won't connect. The antenna would go into the converter. Not sure how much signal you need you may need an rf amplifier if the signal is poor in your area.

PICTURE SEEMS TO BE BLURRED WHEN ITEMS MOVE FAST ON SCREEN, ESPECIALLY PERSONS IN CLOSE UP.


The Sony Bravia KDL-32BX320 generally gets excellent reviews (4.5 stars out of 5) from owners, so I have to wonder what you're watching.

This is an HDTV and should excel when provided an HD signal to display. SD (standard definition) signals often look worse on an HD display than on an SD display. An HD signal is only available via the following ways (reference the image below):9_27_2011_4_28_11_pm.jpg
1) An "over the air" (UHF / VHF) antenna is connected to the cable / antenna input and there is a broadcaster of HD content nearby (only an over the air antenna can input HD signals to this jack - no cable boxes, etc.).

2) An HD Cable TV, DirecTV or Dish Satellite set top converter, Blu Ray Disk Player (or other HD source is connected via HDMI or Component RGB jacks.

3) An HD video played back from a computer hard drive connected to the VGA jack (when the computer is equipped with a modern processor and video card).


You will NOT be able to view HD video if:

1) The source material is a SD (non-HD) source. An over the air antenna will not provide HD signals if the broadcaster does not have HD content to show or is not capable of broadcasting in HD. Digital is not necessarily HD.

2) The source material (other than over the air antenna) is connected via Antenna / Cable jack.

3) The source material is connected via Composite jacks.

The USB jack is generally not an input for motion pictures, but may display stills - depending on the TV's ability to play the format they are stored in (jpeg, gif, bmp etc.).

Hopefully, this will help you solve the problem you're having with the picture. Good luck!

How to Hook Up a Receiver to an HDTV

Though it utilizes the most sophisticated technology on the plant, an HDTV is extremely easy to hook up to a receiver. Home entertainment systems are designed for compatibility, whether it is a cable or satellite receiver, a DVD player or a stereo sound system.


Instructions

things you'll need:

* HD television
* HD satellite or cable receiver
* DVD player
* Stereo receiver
* AV cables
* Cable connector
* HDMI cables


Examine the back of your HDTV. You will see a series of input jacks for AV cables, (typically color-coded white and red for audio and yellow for video), as well as an antenna input and one or more HDMI input jacks. There will likely be a number of them, but each one should be distinguished with a label ("video," "cable" or something similar).

Attach the cable connector from the cable or satellite receiver to the antenna input on the back of the TV.


Connect the AV cables to the DVD player, VCR, stereo receiver or whichever other component you wish to connect to the television. The cables should line up by color: place the white cable in the white input jack, the red cable in the red input jack and the yellow cable in the yellow input jack. All three cables from each component need to go into the same label input jacks. Usually, they will all line up in a vertical row.


Find the HDMI output jack on your receiver or DVD player (some receivers will not have them--they are necessary to receive a high definition signal--but can still play on the TV through the cable connector or AV cables). Attach one end of an HDMI cable to the output jack of the receiver and the other end into the input jack on the HDTV.


Turn on the TV. Access the menu with your remote, and follow any instructions it gives you. Your HDTV may require a few additional steps to complete the hookup of the receiver (though not all of them will).


Access the "input" button on your TV remote. This will allow you to switch the TV signal to one of the cable connections you have just made. For example, if you attached the HDMI cable to the first of two HDMI input jacks, the TV will flash "HDMI 1" on the screen to tell you that is where it is receiving its signal.

Tips & Warnings

*

Not everything that can be hooked up to an HDTV is capable of playing in high definition. The signal needs to be HD as well, which means that only HD broadcasts, HD DVDs and Blu-Ray DVDs can play in full high definition (though "upgrade" DVD players will allow normal DVDs to play at an enhanced picture). You can still hook receivers up to an HDTV, and it will still play broadcasts from them as clearly as the signal permits.

It's staying on 480i sd why not 1080i


There's only one way to get that TV to switch from 480i (which is an SD or Standard Definition signal) - that's to provide it with an ED or HD resolution signal (a 480P signal is often called ED or Enhanced Definition while 720P, 1080i and 1080P signals are called HD or High Definition).


steve_con_14.jpg
The old standard yellow composite video cable.
.
You will not get ED or HD signals through the old composite RCA phono jacks (usually yellow in color), either. You'll need to use an RGB (red, green and blue) component video cable, HDMI cable, DVI, or other type supported by both your TV and the video source (CATV box, Blu Ray disc player, Satellite converter, etc.). More on this, later.
steve_con_15.jpg
RGB cable.

steve_con_16.jpg
An HDMI cable - this provides Digital audio signals, too.
.
steve_con_17.jpg
A DVI cable.
.
First, you'll need a source capable of sending ED or HD signals. This can be a progressive scan DVD, Blu Ray player, HD Cable or Satellite converter, or a simple TV antenna. Not all DVD players are capable of the 480P progressive scan output - it must be labeled as such. The DVD movies are not labeled progressive scan as they all will play back at 480P if played in a DVD player capable of progressive scan, otherwise they play at 480i. A stand alone Blu Ray player or one in the Sony PlayStation 3, the older HD-DVD in the Xbox360, (it is important to note that the Nintendo Wii can output either 480i or 480P signals only when connected with their special component video cable), "set top boxes provided when you choose HD service from your local cable provider or satellite TV provider are the main sources for signals better than 480i. As mentioned above, the old standard yellow video jack is not capable of supporting signals better than 480i. You must use the HD jacks and cables between to get these signals into your TV.
steve_con_18.jpg
The Wii 480P cable assembly - includes stereo audio, too.


Lastly, if your TV has an ATSC tuner (it is not uncommon for it to have an NTSC tuner and CATV tuners as well), you can input a UHF antenna directly into the the antenna terminals on the TV. Broadcasters in most areas have been moved into UHF bands - but some areas have one or two that operate in the VHF bands still. Check antenna web for information and help selecting antennas and broadcasters in your area. The nice thing about the antenna method is that no other cables, converter boxes, etc are needed to enjoy HD signals - plus - they're free!

Just remember you need a source capable of ED or HD signals and a way to get those signals to your TV. The yellow composite cable is from days ago and only passes 480i signals.

I hope this helps and good luck! Please take a moment to rate my reply - thanks!

Do I need a tuner or converter box for this type of TV?


Most projection tvs even if they say HD need a converter box. This is because the HD tv part is referring to playing hd video through the component inputs. This input is typically where you would connect a dvd player or blue ray player. Most projection tv's where made before the transfer of analog to digital tv.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

Screen goes black and resets during HD shows


I just posted this to another Sony owner:

Another point; HD Ready does not mean that it is HD compatible without the addition of an optional part.
The title only implies that it can be adapted to HD reception.
If you did not purchase it with the set, check your user guide to see what you need to make it whole.
You may have to seek this add-on on eBay since it is not guaranteed that Sony will still offer it.
