MD31347 startup problem

[Xian2]

Hi,

I have a problem when starting the MD31347 TV : the last couple of days I get a flashing screen. The tv switches between different colours : black, green, red, blue, ... There is sound : you can hear sound from the current program, but no image.

Disconnecting the power or pushing different buttons on the remote does not help.

After a while (20 or more minutes) the tv goes back to normal by itself.

Anyone an idea ?

Thanks

moin @Xian2 und willkommen/welcome

was du machen kannst ist eine Reststromentladung durchführen:

Reststromentladung = Netzstecker ziehn, alle Kabel ab und Einschaltknopf für 10 Sek. drücken.

wenn das nicht geht: Erstinstallation durchführen (Werksreset)

Sollte das auch nichts bringen, den Support kontaktieren.

what you can do is carry out a residual current discharge:

Residual current discharge = unplug mains plug, disconnect all cables and press power button for 10 seconds.

if that does not work: perform initial installation (factory reset)

If that does not help, contact the support.

Hallo, danke für Ihre antwort.

Unfortunately, that did not help (left the tv unplugged for more than 7 hours). Haved asked for a RMA.

scheint sich im "TV opens with Burn-In mode" zu befinden.

siehe als Beispiel: https://forum.iwenzo.de/telefunken-vestel-t40781l-bild-wechselt-sekundentak--t61627.html

habe aber kein Unterlagen/service manuel für MD31347 gefunden

seems to be in the "TV opens with burn-in mode".

see as an example: https://forum.iwenzo.de/telefunken-vestel-t40781l-bild-wechselt-sekundentak--t61627.html https://electronicshelponline.blogspot.com/2013/01/vestel-17mb22-service-mode-adjustment.html

But I have not found any documents / service manuel for MD31347

@Xian2 

wenn noch garantieansprüche bestehen, ist es dann nicht besser den support zu kontaktieren?

if you still have warranty claims, you should better contact the support.

it looks to me like a serious hardware or software issue

Hallo, vielen Dank für Ihre Hilfe !

TV worked for a day this weekend, now broken again 😞

Opened a call with Medion to repair the tv : is only 3 months old.

BTW : this hack worked on this TV  : https://electronicshelponline.blogspot.com/2013/01/vestel-17mb22-service-mode-adjustment.html

But no solution ..

Again, thanks for helping !

bitte schreibe uns, wenn der TV wieder da ist, was die Ursache war.

Du schreibst:"BTW : this hack worked on this TV"

Ich weiß

Darum habe ich auch extra geschrieben: "siehe als Beispiel:"

und nicht: damit kannst du die Software deines TV verändern.

Es ging ja darum, zu erklären,  woran es liegen kann wenn die Unifarben ständig wechselt.(TV opens with Burn-In mode)

please write us when the TV is back, which was the cause.

You write: "BTW: this hack worked on this TV"

I know: smileywink:

That's why I also wrote extra: "see as an example:"

and not: that allows you to change the software of your TV.

It was about explaining why it can be when the solid colors change constantly (TV opens with burn-in mode).

i guess it is not that smart, to talk about a hack that open here, when your device is broken and the support people is maybe watching your comment...

... you can do, when you have your TV back and when it is working again.

Hi,

small update : service-engineer came by yesterday. Still no joy :s

Probably motherboard ... hopefully : he replaced everything, but it still did not work. Mayby it was the wrong replacement motherboard (Vestel). Now I'm waiting for another replacement motherboard.

This was probably the first and last Medion TV I bought. Was a happy customer before, but now ....
