HDMI Headscratcher Hannspree 37" YTO8

[spottydog10]

I am having a problem with the HDMI socket on my Hannspree 37" YTO8 TV.

I have been connecting my pc to the HDMI without problem for the last couple of years now it suddenly comes up with "No signal".
Nothing in the pc has changed and I have tried a laptop also without success.
I have checked all the settings on both the pc and laptop and changed cables. Both computers fail to detect the TV as a monitor.
I have tried another HDMI monitor and it connects fine and I tried a different video card in the pc a few weeks ago with no luck.
Tonight I reinstalled Win 7 from scratch with no updates and the original video drivers just in case an update had buggered something, no luck.
If I plug my BT Vision box or my DVD into the same socket it works OK.

What other steps can I take to troubleshoot?
Is it possible that the HDMI socket on the tv is faulty to the extent that it will not accept a signal from a computer but will from a BT Vision box or a DVD Player? If so what is the solution?
BTW, I have turned everything off at the wall for 15 mins, disconnected and reconnected without any joy.
I have tried (and failed) to find a factory reset code for the TV.
Thanks,
Mike

May be the socket, solder joints at the socket, the HDMI IC had failed, or may be the Voltage feeding it is no longer there.

Thanks budm,
What would the first step for me to verify the problem?
Take the back of the set and see if there is anything obvious?
I'm no tv repairman but I'm pretty good with pc repairs.
Thanks,

Look at the main board where the HDMI port is, there is should an IC close by.

Thanks bud,
I'll have a look this evening.
Not sure what I'm looking for but I'll take a photo.
BTW, is there any voltage risk with this set, obviously I'll have it switched off and unplugged at the wall
Cheers,
Mike

If you only deal with the main board, you should be OK. Just don't touch the power board, at all.

Re: HDMI Headscratcher Hannspree 37" YTO8

OK, got the backoff alright
The hdmi port is inside a silver box casing alomg with other stuff (see pics)
The port seems tight enough
I'm a beginner here, what do I do next
Thanks,

You need to remove that shield.

Have you tried a factory reset on the tv i dont know if it will fix your problem but worth a try i guess whats the model number of the mainboard? some times its on a white sticker.

sorry just re read post 1 and saw that see if you can find the mainboard numbers it maybe used in other sets so you can probably use the factory reset code from another make of tv.

Re: HDMI Headscratcher Hannspree 37" YTO8

did you try this
Turn the TV on.
Press the {-/--} {9} {9} {1} buttons on the remote.
The Service Menu will be displayed.
To change pages, press the {MENU} button then
the {-/--} {9} {9} {1} buttons again.
Press the {EXIT} button to exit the Service Menu.

or if your tv has buttons on the top try this
power on the tv, hold down the right two buttons (CH UP & Enter) on top of the TV then press the Power Button

Re: HDMI Headscratcher Hannspree 37" YTO8

ok see if you can get the mainboard numbers for us and has the set got the buttons on the top of the tv?

[spottydog10]

Re: HDMI Headscratcher Hannspree 37" YTO8

Vince, the buttons are on the bottom of the set.
I cant take the thing apart again till tomorrow but I do remember a couple of the chips were Samsung.
PS, where would the name of the mainboard be?
