LCD32880HDF problems

[e3gsr]

Hi guys me again.
I have been given an Alba LCD32880HDF it turns on backlights come on, then blue screen with channel number etc, but the volume bar comes on and the volume is going down without touching any buttons, Then the screen just goes blank, but it has sound so i'm told. No source has been connected to confirm this. Do you think it may be the main board that is faulty? as the screen stays on for varying times the longest being when it is first turned on.
I have noticed that the large chip on the board does get quite warm even in such a short time.
Any help would be much appreciated, Thanks in advance.

Is this a model with push buttons or a touch panel for buttons?

Has the button board had anything spilled on it? I believe the buttons are at the top?

I have a 22" alba/vestel in the bedroom, also have a 19" and sold a 15", they all had buttons on top.

edit; Never mind, you answered as i was typing. 1 Finger typer here.

Re: LCD32880HDF problems

noting spilled on it as far as i can see, my buttons are on the right hand side this one is a 32" if that makes any difference. to be honest that was my first thought lol.

Is the remote anywhere in the room?

Sounds silly but might be causing the problems.

Its prob not so lets just get that out of the way first.

I always check the simple things first before anything as its them that have you over the most.

Re: LCD32880HDF problems

Would take a stab at the touch board myself, try removing it and cleaning the capacitive touch contacts.

Sienoki's advice is also valid as he showed me this model with a bulging cap.

[e3gsr]

Re: LCD32880HDF problems

Cant see any bulging caps at all,Tried disconnecting the touch board as its doing it and it carries on, So dont think its that but thanks for all the suggestions, keep them coming lol.

Re: LCD32880HDF problems

just a quick question for you, I have been looking at mainboards for these and can anyone tell me what is the difference between v1-v4 will they all work in this tv as they all look physically the same.

[e3gsr]

Re: LCD32880HDF problems

i think mine may be a version 1 as the number under the sticker is 17mb24-3 060309. can anyone confirm this?

[e3gsr]

Re: LCD32880HDF problems

right guys quick update for you after having a fiddle when i came home i found that if you turn it on with the number buttons you get this screen. It will sit there at that screen for ages no problem so im guessing it is not power supply problems or am i wrong? it will also bring up another one if you try to change channels that has an ok button on it at this screen you can adjust the volume but the menus only flash up for a second then go off again.
Any thoughts?

Re: LCD32880HDF problems

OK try both of these methods:

Method #1
TV in standby.
Turn TV on.
Press MENU on remote.
Press 4, 7, 2, 5 in succession.
This should bring up factory menu - select RESET option.

Method #2
TV in standby.
Turn TV on.
Press 4, 7, 2, 5 in succession.
Press MENU on remote.
This should bring up factory menu - select RESET option.

Re: LCD32880HDF problems

slight problem menus don't stay up long enough to do anything. Just flash up then disappear.

[tom66]

Re: LCD32880HDF problems

Disconnect the touch panel and try again.

[e3gsr]

Re: LCD32880HDF problems

wont even turn on with it disconnected just flashes the power light constantly.

Re: LCD32880HDF problems

Darn must be a chassis detect problem. Would be hard to eliminate that without unplugging it but TV detects this and doesn't like it.

For Vestel just match the main board chassis part "17MB24-3" etc, the -3 is important and check the HDMI ports match.
