sega mega drive model one with horizontal bars

sega mega drive model one with horizontal bars what can i do to make them gone i have cleaned the cart slot i have 3 mega drive ones with th same prob hope someson can help me out

 

Pictures??

 

I'm gonna guess you mean on the video. Make sure you clean all your connections, even on the TV, because it really wouldn't make sense that all your MD's would do that, I would have to guess it is whatever you are hooking them up to. If it is the TV, and cleaning stuff doesn't make it go away, you may have some dead ports or something.

 

i have cleaned the console with the card trick and cleaned everything

 

RGB SCART?

My LCD TV does that with a Mega Drive through RGB. Try it on a CRT or with a different lead to see if it persists.

 

ok i will now
i will upload a picture asap

 

as you can see its the same i dont have any more crt tvs to test
as you can see the bars are still there i have checked the board for dry jonits as far as i can see theres none

 

Try a different PSU. Is the sound clear via the headphone socket, or is there a noticable humming sound when the volume is all the way down? That's sometimes a good clue that the PSU is incompatible.

 

i am usein a sega ac model 3804 9v 850mamp it does humming if theres no game in the console if i turn it all the way up
so i looks like i need 10v 1.2amp any one got a spare one to sell

 

for now i am going to use my mega drive 2

 

Ooer, how odd. Do they move at all, or do they stay static?

 

they dont move at all

 

Yes it's probably noise from the PSU as the console is drawing a higher current than what the PSU can output. Get hold of the original PSU (Sega model: 1602-05) or one with the correct rating, and the problem should disappear.
Ebay's usually littered with them, but you may have to ask the seller for more info if the pic(s) don't show the rating clearly.

 

Sellers on ebays are utter arsewipes. Dont mention or assume wrongly which model its for then refuse to refund you

 

ok i will get one soon and i will let you know what happens what was sega 3804 ac used for

 

hi i found one 1602-05 in my mega cd 2 boxed so i tryed it again
it still came up i the bars if i use rf it gone so i think it the a/v cable
i will make up or buy a rgb cable and see what happens

 

Your a pretty handy feller so i guess you've down this but have you tested all the caps?

 

i have had a look at all the caps seem fine but i am saveing up some cash to complete set for my mega drives system i do replace most cap every time i buy a sega even if they dont need changeing the worst is the model one mega cd /sega cd they always like a game gear for caps
i will let you guys know what happens when i have change all caps
i only buy 105c type the long lasting and i use pcb lacquer to protect the sega consoles from dyeing out most game gears and mega cd model ones
need cap replacment
