Medion 42" (MD30163DK)

[nostrike]

Hey All.

This looks like a nice forum and I hope you can help me.

I have a Medion 42" LCD TV with a blue screen.

I can turn it on, use remote, see menu on the screen
and hear the sound from movies (played through DVD player).

There is no picture, just blue screen, except the menu is there.
It is like there is no signal, but the TV only complains when I remove
the dvdplayer (no signal) , It does not say it, when it is plugged in.

I have changed the PSU (17PW16-2)
and the Mainboard (17mb26-2), because it would not start at all first.

Could it be my Tcon board or something else??

Hope someone can help me.
Thanks in advance

First thought is have you got all the connectors back in place?
Second - can you try another input insted of dvd- computer?

Yes, have checked the connections three times to be sure.
Have Tried with antenna, pc and dvd player.

Did you own the tv from new - have you seen it working properly.?
Do you still get sound with PC and Antenna - have you anything to go in the scart socket or hdmi.?
Did you change the source using buttons or remote control?
Check in the menu is there a child control switched on?
Is there an option for resetting the tv in the menu.?
Can you run a channel search from the menu?
Do you have a soldering Iron and Multimeter and can you use them?
Unless someone recognises this fault you will probably have to post
Pictures of the front and backs of the boards in the machine.
As a start could you post one with just the back off the set with the leads in
place so we can see the general set up.
Were the replacement boards the same numbers and revisions as the old ones - and have you still got the old ones?

When you say DVD player is that internal or external - if you disconnect the internal
and connect to pc do you still get no signal message.

Got it to work.
Thank you.
It was the child safety thing.

My next problem is that I can only select Digital TV as source,
PC, HDMI or DVD I can´t select them in the menu :S

Have the manual , but that does not help my much,
when the other things are not there.

Probably a Vestel.

Press 4-7-2-5 then menu. You must press them 0.8792387 seconds apart and in that order. (It's extremely sensitive, at least on the Vestel TVs I have.) You should get into a secret service menu that lets you configure some core settings. Look for the option for inputs and set it up, enable the ones you need. While you're at it, add the Dolby sound decoder, 7-day EPG (if it only has a now-next one), extra picture settings, and some other features you'd normally pay extra for .

Tom66, you are a f**cking genius

It works perfect.
Only one thing is wrong
and that is when playing a dvd movie (dvd player),
only colour is blue (but must be a setting)
because PC works perfect with the TV.

Re: Medion 42" (MD30163DK)

I've never seen a 42" with a built in DVD. Crazy!

Try enabling the "Medion Mode", if it's available. Custom settings for Medion TVs. I've seen it on one TV - no idea what it does though!

There may also be a mode for the DVD player i.e. 0 - 7 or a list of DVD player units that they may use, if so try selecting each one and seeing if it works. (You may need to restart the TV every time while doing this.)

If you still can't figure it out, there's a reset to factory settings option somewhere there. That will reset it to the defaults for your model so it should work like new. That's assuming the main board is from the same model... given Vestel manufacture about a million different variants, it's probably not so easy.

What input are you using? I've got a 32" Goodmans in the shed which works well on all inputs. I had to reconfigure it after the memory got corrupted so I know how everything is set up. I'll see about what it has set up for those inputs tomorrow.

Re: Medion 42" (MD30163DK)

I tried Scart and S-video (the yellow one). Still Blue picture. Thanks Tom

Have not searched for Channels yet, but the normal "no channel" noise picture
is also blue, so it must be a picture setting

Re: Medion 42" (MD30163DK)

Got the settings right now. The picture is beautiful
Thanks tom66 and selldoor
