Scaler board and cables - where to buy???

I get a blank screen that changes colors every few seconds: blue, then yellow, then red, etc. I can't bring up the menu to try and select an input source -- I was told $350 for the board itself (+labor)... Any idea where to buy at cheaper price? Thanks BobbyJ

The DP26649 model TV has three inputs; video one (which is fine and has all color and everything), video 2 (if you plug them in certain ones the best i can get is full sound and all but its black and...


OK, here is the breakdown on whet you are doing wrong.

Video 1 - Composite -
Video - Yellow
White - Audio In - Right
Red - Audio in - Left

Video 2 - Components - HD - RGB = Red, Green, Blue
Video -
Red - Red Colors
Green - Green Colors
Blue - Blue Colors
White - Audio In - Right
Red - Audio in - Left

Your GameCube will only work on Video 1, unless you buy an HD (Component cable). You will need to buy HD cables for your device connected to Video 1 to work on video 2. I will assume it is a DVD player. This is a high definition cable to produce a better picture. Let me know if you do not completely understand

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

It doesn't show red color. i tried to do factory reset. but still problem.


1.After turning on the projector, press "+" and "-" buttons on the control panel
simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3 While in Self-diagnostic mode, the screen will run a seven-color-cycle test as
following:
Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct.

Contact Dell if the colors are not displayed correctly.

Cannot get DVD's to play on our TV.


It depends on what kind of inputs your TV has; here are a few of the most common, all of which your DVD player supports (best quality first):

1) COMPONENT VIDEO (Red, Green, Blue)
If your TV has three inputs for video colored red, green, and blue, this is your best bet for quality video from your DVD player. You may need to buy a component video cable from the store (somewhat pricey, but great quality) which consists of three cables (again, red, green, and blue) stuck together. Just plug the red/green/blue cables into their correspondingly-colored ports on both the DVD player and the TV.
That covers your video. To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the red/green/blue cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

2) COMPOSITE VIDEO (Yellow)
If your TV has a yellow input for video, just use a regular yellow RCA cable. Plug it into the yellow video-out jack on the DVD player, then plug the other end into the yellow video-in jack on the TV.
To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the yellow cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

3) COAXIAL JACK (Antenna port)
If your TV only has a coaxial jack that you currently plug your antenna or cable line into, you'll need to buy an RF modulater and a short length of coaxial cable (you can find these anwhere: Walmart, Radio Shack, etc).
Plug the RF modulater into an electrical outlet, then plug your antenna/cable line into the "antenna in" jack on the RF modulater. Take the coaxial cable that you just bought and plug it into the "antenna out" jack on the RF modulater, then plug the other end into the antenna/cable jack on the TV. The RF modulater should have a switch on it somewhere that sets either the number 3 or 4; depending on which number you pick, that's the channel that your TV has to be switched to to view the DVD player.
Now you're all set to connect to your DVD player. Just follow the instructions in section (2), only now you're going to plug your cables in the RF modulater instead of the TV.
(I hope this wasn't too confusing; it really is a lot simpler in practice than it is in explanation...)

I am trying to connect an akai dvd player to directv, please help


ruettab,

good day. to connect your any DVD player to any TV screen always remember this color code

from DVD back part:

yellow = video out

red/blue/green( in a row) = component video out ( this can only be used for screen with component video inputs)


Black = digital audio ( rarely use unless)
Red and white (in a row) = Audio output (left and right audio)


where to connect from TV screen.

Locate where A/V INPUTS (audio/video socket) from your TV screen, you can see it either at the BACK/SIDE or somtimes in FRONT of TV screen , having marked as "AV1"AV2"AV3' .

Once you found TV input, you must first have RCA cable (color code cable to connect player to screen) then connect the RCA cable at the back of your DVD player, simply follow color code

RCA yellow marked cable = DVD yellow socket
RCA RED and WHITE marked cable = DVD RED and white socket (second row for your player)

then connect the other end of the RCA cable to TV screen, first select which input where you gonna place the DVD player ( either AV1, Av2 or Av3 if do have multiple inputs)

once decided which INPUT to connect the player.
ex. if you select AV1 as input there would be 3socket on its row (yellow/red/white)

now connect the other end of RCA cable to the screen by following the same color code:

RCA yellow cable = TV screen A/V1 input yellow socket
RCA RED and White = TV screen A/V1 input red and white socket.

cheers,
mark

My panasonic's red color and blue are switched wat do i do?


Hopefully this is external to the TV which makes for an easy fix. Look at the panasonic menu, is it clear or distorted? if not you may have just swapped the blue and red component wires on your cable/sat box or dvd. Component video uses 3 wires for your picture (red, green, and blue).. the video runs on the green wire, but the red and blue are just chroma (color) so if you get them backwards you will get his issue. If this is not the case and you have an internal failure, there is something wrong in you video processing. Narrowing down can be achieved by checking all inputs and resolutions. If its on all inputs, its likely after your video switching IC, if not, before. Another good test is HD which bypasses much of the scaler (doubler) circuit that upconverts all non-hd video to HD for displaying on screen. If all is bad, but HD is good, the scaler circuit is faulty. All this video circuitry is usually encompassed by the Signal board, but specific models will determine exact repair procedure. A local repair shop may be the best bet if its a tv failure.

New system - no color on screen


the cable colors have to match the tv ones if you have different colors on cables then look for the label on the cables saying video or audio (red)=audio (white)=other audio (yellow)=video EXAMPLE if the cable colors are different than the tv then if the label on the cables say video and the color is blue etc. then you have to put it on the yellow putin on the tv no matter the color. If it dosent work then try holding the cables in many angles try pulling them or anything unlit they work get something to hold them up if that dosent work then i think you should buy new cables.
