Hi and welcome to FixYa,

Based on your post, no matter what you use, there is no display shown. This would indicate that the signal controller/processor is faulty. This board provides the selection of which source to display. Although repairable and relative easy to fix, this of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service/repair manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

To your other concern of a user's manual, pls try here.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

    I think if you have warranty cover, better to take it to supplier and get replacement.

ON SCREEN HAD POWER ONLY V8.02.8


FOLLOW this instruction and fix it. God bless you
·
Connect the component video, HDMI1 or AV1 cable from the component device (such a DVD player) to the appropriate input port on the TV. This port may say "Video IN" on the back of the TV. Ensure that the cable is connected securely at both ends.
· 2
Use the remote control's device button(s) to access the menu and select the input through the menu that matches the type of cable input connected to the back of the TV. For example, if you connect the cable to the HDMI1 input port on the back of the TV, selecting anything but the HDMI1 option with the remote control may cause the "No Display" message to appear, which usually means that the TV is not receiving a signal at the connection input you have selected.
·

· 3 Turn the power on to the component you want to view. If the power was off, turning it on will activate the display and replace the "No Display" message.
· 4
Test any other connected components at their selected inputs to see that the TV is receiving the video signal properly from those sources.
· 5
Check with your cable or satellite provider if their set-top box is the source of the "No Display" message and is powered on, to see if the problem is caused by a disruption in their service. If using an antenna, adjust the antenna and re-scan for available channels.

I don't know what channel to go to to be able to play my dvd player


where did you hooked up the connector wire coming from the dvd player, in the component input or at the RF jack of the tuner of the tv?. if you plug at the component input of the tv you will select AV1 or AV2 etc. in the settings. but if you hooked up into the RF jack you can select channel 3 in the tv but at this time you need to have manual tuned in the tv to get the signal coming from the dvd player or xbox.

I have a 32" flatscreen


Different video signals use different connections ...and we are speaking ONLY the video(NOT including the audio connections)
  • Composite Video (typically colored Yellow) uses 1 RCA connection on your TV
  • Svideo (uses 1 svideo connector on your TV) a circular connector with 4 pins in it
  • Component Video (typically colored Red/Green/Blue) uses 3 RCA connections on your TV
These are the common analog video signals....You cannot mix and match these and plug a composite (Sometimes called AV in menus) into component etc
If both your sources (wii/DVD) you want to use a component signal to your TV (which BTW is the best quality of the 3 I listed) you will need 2 component inputs on your TV
OR
run it through a high end receiver (that will act as your switcher)
OR
buy a small stand alone switcher, something like: http://www.amazon.com/4X1-HD-Component-Av-Selector/dp/B000BVIBGI/ref=pd_sim_sbs_e_4

settle for a lower quality DVD signal and use the Composite video out (yellow jack) into the Composite Video In on the TV and use the component for wii

I hope this helps,
Magoo

DVD player won't work on my 27gt615


alexa,

good day, if youre saying that you program the DVD to work on channel 2 or 4 does it mean you convert the signal of your dvd player from A/V output to RF out?

because the simpliest way to connect your DVD player to TV screen is by using RCA cable ( 3 wired cable being color marked as yellow/red/white) yellow = video red and white = audio

the connection would be: from dvd back part you'll see colored socket yello/red and white. connect the RCA to those socket following the same color .

and from the TV screen there should be A/V input socket. can be locate at the BACK/Side or FRONT of the screen marked as
"INPUT" ( AV1, AV2,AV3 if multiple inputs). Then select which input you want to place your DVD player ex.AV1 (from AV1 there will be 3 scoket in a row, yellow/red/white)

Connect the other end of your RCA cable following the same color code to TV "AV1 INPUT" yellow = yello/red =red/white=white. then from the remote commander of your TV screen locate a button marked as "TV/AV" or "A/V" press this button until the screen display switch to AV1.

cheers,
mark

DVD input with signal access


IF I understand you correctly, the VCR, Satellite, etc is connected using an RF modulator/coaxial cable wire going into Antenna in

IF this is true, then you have an AV IN port (red, yellow, white) free on the back. Just connect the red, yellow, white from the out of the DVD - you can use 1 or 2 - just remember which one you used; and connect it to the AV IN on the back of the TV.

THEN press ch down on the TV remote until you get to "AV1" - it is below channel 2; double check DVD player to make DVD is playing and voila!

Hook up vcr


Unhook the dvd cables from the AV1 ports on the tv. Then hook these DVD outputs to the inputs on the vcr. Then hook the vcr outputs to the tv inputs (AV1). The tv and the vcr must then be set to channel 3 in order to watch the dvd (and possibly also some menu settings such as setting everything to "component video" and/or setting the tv/vcr button to "vcr. Also set all "3 or 4" switches on the back of all equipment to channel 3. Also, don't forget to go into your tv menu and choose AV1 when you want to watch the dvd and/or the vcr.
You can also try connecting your dish to the vcr and then the vcr to the input on the tv where you HAD the dish connected. There are several combinations you can try, but just remember to always put output cables to the INPUTS of the next piece of equipment in line, and set your menu settings appropriately on all equipment whenever you change from one machine to the next.
If all this fails, then here is a 100% positive solution. Buy an "A/B" switch. It has two inputs and only one output. You could leave the dvd connected as is and connect the dish and the vcr to the two inputs on the A/B switch. Then hook the one output of the A/B switch to the tv. When you change the position of the A/B switch back and forth, you will be changing over back and forth from dvd to vcr. You can move the A/B input selection switch manually or you can buy a remote controlled A/B switch and do your switching with the remote that comes with the switch.
