I have a Yamakawa 288K VGA DVD player. Accidentally, I changed something in its menu, and now I don't get any signal out of it. My TV just doesn't recognize any. Can you help, please? Thanks in advance!
You may have already tried this but try connecting the player via it's composite and component cables. It's possible you switched off your VGA connection in the menu and no image can be displayed. Worth a shot if you haven't done it already.

If you have a DVD player you can do a test to see if you have a bad tuner in the TV. Using Red, White, and Yellow cables hook up your DVD player to the corresponding jacks on the back of the DVD player and INPUT on the back of the TV with corresponding jacks as well. Turn on the DVD and TV and go to the TV menu and find the input that you have the red, white, and yellow jacks hooked to and see if you get a picture from your DVD player. If you do get a picture you probably have a bad tuner in your TV (if you are sure your cable signal is good). This setup bypasses the tuner. Let me know how it goes. And if you haven't done so be sure you have the right input for your cable signal correct in the menu as well.
Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.
If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.
A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)
Bad FBT Flyback Transfomer.You need to also check the Hori output Transistor,chances are if FBT is bad then Hori output will be shorted.
Mats Electronics should have FBT 1-800-628-1118
try different type inputs on your TV- HDMI, component, composite
then look in the menu of your DVD player- with no disc in it- find "setup menu" then find "video output format"- select the one you are using on the TV, the options will be HDMI, YpBpr (component) , video out (composite)
What is your TV input connection? Are you using Antenna? Cable? Dish?
The Unusable Signal sounds like the TV is not getting a signal. Does your TV have a built in HD Tuner?
If you are using Antenna you might want to try setting up the connections and it should search for quality channels that you get good signal strength. If you are on channel 2 and there is no over the air channel 2 it may say "unusable signal".
The TV supports 1080i so if your hardware is plugged into the Component Cable Connection for Digital TV on the back the signal will come out 1080i as long as the hardware supports the size.
For example, my 360 is connected like this and when the dvd player is in use it upscales from the 480 format dvds use to 1080. More on the HD-DVD for the 360 and how it handles the sizes here: http://www.engadgethd.com/2006/09/21/xbox-360-hd-dvd-playback-maximum-1080i-via-component-1080p-vga/
Kind of an old article since the newer 360s have hdmi and support 1080p that route.
