It's not moving the mainboard that causes problems to happen. Alot of people don't know but the screws inside the Dreamcast that hold the mainboard down are different sizes and there is a place where a longer screw isn't supposed to go and it will go in to far and touch the mainboard and cause problems. But that's besides the point of your question but could have been done before. There could be a bad capacitor or a break in the solder joint where the AV port is at also.
Lemme guess.. Your trying to run it from the cable connection and not av-cables?
It's a pain trying to get a cable connecting game consoles working on newer televisions with a digital tuner installed. Your gonna have to go the annoying route of searching for the channel through your setup screen or you might be able to access the channel that it is set for using your remote for the tv (channels 3.0 and 4.0 still work with older consoles using the cable plug).
Just type in either of those channels with your controller unless you went the search route.
If your playing the Dreamcast with audio-video cables, you would have to find exactly which input your using.
Probably not. Better picture results are achieved with either S-Video, standard RCA AV cable (yellow-white-red), or YUV component cable (red-green-blue) (component output does not have audio - this requires extra cable to be connected). The video via either one of these 'AV' connections is stunning (based on a standard 16:9 LCD TV using a Panasonic DVD recorder).
RF tends to be lower quality - as opposed to AV/digital input. AV input/YUV component handles digital better. No one connects their DVD devices to their TV via RF (either directly to the antenna socket or with a modulator/attenuator) anyway. Because a VCR is mostly analogue, it will work fine with an RF connection, but DVD is digital, and so won't work as well, if at all.
RF also goes through the tuner in a TV, creating cross-interference, whereas AV is a direct input and is separate to the tuner.
I would say an RF modulator would not be designed to handle the output frequency that your DVD device generates. Throw the modulator out, or perhaps get another TV, or use RCA cables instead if the TV has AV inputs. Whichever is cheaper and easier, but don't use RF accessories except a standard antenna if/as required.
Hi the chances are its the cable at fault try giving it a good wiggle all the way along and make sure its plugged into the dream and tv properly also make sure your tv is on the correct channel.
if you have got it plugged in via scart lead or the 3 coloured wires then you need to put the telly on av so find the button on the remote that says one of the following av source input or a rectangle with an arrow facing to the right then press that button with the dreamcast on you may need to press it more than once depending on how many inputs the tv has .
let me know if you have any problems and still cant get a picture ok
plz rate this solution as i have a whole page of unrated posts, thanks
This might not help everybody but it might be a cheap fast solution to the "Xbox 360 no picture but sound ok" problem. I have old refurbished 360 that has had no problems at all. SInce I got it have used it with powerwave cooler attached to the back. This cooler has seperate Outputs for Vga, SVga, audio, component and av. Don't need the microsoft cable at all just standard cables. Always had it plugged in with VGA or SVGA cables and got great picture. I bought new 360 and put the old one in bedroom with old tv which only has av inputs. Got shocking picture that was unwatchable but sound was good. Tried all ways but no different. Seems the xbox plug has problems. If you get the powerwave cooler it splits the xbox output socket in to seperate outputs for everything so you can use it with Vga or Svga cables if your tv has those inputs and it should work fine. Only seems to be the standard AV outputs that have problems. Haven't tried the componet leads but I guess they might work as well. If you only have the old yellow, red and white AV inputs on your tv this wont help you but if you have the other types of inputs it might fix it. The powerwave cooler you should be able to buy for under $20 so it could be a cheap solution for this problem everyone seems to be getting lately. It works for me at least so get one and give it a try.
Maybe there's something wrong with the rf and av cables that you have. Try and borrow some of them from your friend. Or, maybe your RF and AV cables' cords are either bent or wrecked. Try fixing them and try again. If it still doesn't work, then come back.
