..Hi friends ..
Spent most of my morning searching once again for a replacement main board ..
..and maybe I found one that will do the job ..
BN94-01077E

Whereas mine is a BN94-01077B
It certainly looks the same ...i/o connections etc ..
but the number is slightly different ..
Anyone know if there is enough difference to be an issue ?

Its a bit pricey ...so don't want to make a mistake if I do decide to buy it ..
Unless one of you guys has an exact match ...I might well have to take the risk..
The company selling it is SJS ....
Anyone had dealings with them before ? ..and if so ..are they reliable ?

E Parton:
Thanks Dave ..
Surprised when Stewart from SJS rang me an hour or so ago ..
I had emailed them with my address and details ..but without a phone number ...so was quite surprised when he rang me ...having obviously gone to the trouble of finding the phone number himself.
We discussed possibilities ..and there is good chance the 'E' board can replace the B  board ..after various links have been moved which relate to the type of lcd panel fitted ..
We've agreed that I should keep searching for an exact match over the weekend ..but should I come up empty handed by monday ..I'll order one from him ..and attempt to modify and fit it.
..and there is a discount available to Trade registered customers ..

Cure or pure fluke ??
I took the plunge and ordered a BN94-01077E board ..
Mine was  BN94-01077B and couldn't source one anywhere ..
The board arrived this morning ...and although plugs and connections are the same ...its designed to drive a completely different LCD panel thus ...it can't be fitted without major board surgery ..
So I fitted it anyway ..but didn't plug in the lcd panel ...
Connected the dvbt boards to the top edge connectors and powered up..
It went through the initialise process ...but obviously there was bo picture ..
I then removed the main E type board and refitted the B type ..and the previously connected dvbt board ..
My intention was to give up and tell the customer ..he'd have to use a freeview box with it ..but to my amazement ...the dvb menus were back ??
Fluke ...coincidence ..or cure ?
Still not sure ..
It _may_ be that the E board wrote something to dvbt board during its brief lcd panel-less boot up ...making it initialise ...
I'll probably never know ..but a result is a result ...
And the set now functions correctly..

E Parton:
...Hmm
..although I now have this set essentially _working_ ..
I still have an issue insofaras
The backlight shuts down ..ie no brightness/picture ...but ONLY occasionally and for short periods ..when the set is displaying a Dull low brighness Low contrast image ..
Once the broadcast changes to a brighter image ..say a studio picture ..the backlight comes back on ..and a picture is displayed.
In other words ..the backlight is either on or off depending on picture content.
Does anyone know if this is fixable ? ..perhaps by tweaking a setting in the service menu ?
