Sharp LC32AD5E sky?

dragon2611 · 08-12-2007, 12:10

Sometimes when watching sky (standard sky box connected via scart) the picture will blank for a split second and then ext1 will display and then it will come back

Its always just as the adverts come on (sky sports news is the worst culprit) or if you change channel but only sometimes when you change channel, it seems to depend on what channel you were on before and which one you were changing to.

I thought it might be the change from widescreen > 4:3 that sometimes happens with some programs but setting the TV from auto to one of the other widescreen settings didn't help.

Also tried setting Ext1 from auto to pal and it didn't make a difference.

If it's any help?, there are no technical bulletins on this model, but there are firmware updates dated 22/10/2007 for both the set and the DTT side.

Some of the other Sharp sets have updated software to cure a blanking problem on specfic satellite channels.

No idea what firmware mine has, or how I would go about updating it..
I did do a check for updates but it said there wasn't one... although unless it was being transmitted at the time (not likely) then i guess it wouldn't

Over the air updates are only for FreeView, not for the TV's own software - it requires an update from a computer, by an engineer.

However, I've no way of knowing if it would make any difference?.

Bah whos bright idea was that one (requiring an engineer) why do these companies never bother putting out the updates in such a way that anyone can just bung a computer on the device and update it themselves.

They do it for routers.etc sometimes so why not other stuff

Because if you get it wrong, you trash the TV!.

Only if you destroy the bootloader

I've not yet bricked to the point where it couldn't be resurrected with a full re-flash.

Except it's a completely different procedure, if you mess up the serial upgrade, then you can't recover using it. You need an I2C interface adaptor and a different technique.

Hmm silly if you ask me but then i'm not an IC designer

Essentially you're altering the entire OS of the TV, including the BIOS (in PC terms) - trash the BIOS, you trash the motherboard - unless you have some other way (that doesn't require the BIOS) to reload it.

Dual chip Bios in some of these newer motherboards for exactly that reason.

Lot of devices running embedded firmware are ok as long as the bootloader survives as they go into a failsafe mode where its still possible to communicate with the thing to flash it again (but thats about it)
Sometimes you have hit a certian button sequance to get to it but its there.

Mine was updated today by an engineer who called to sort out my speakers vibrating. It needed a PC with a parallel port and a cable into the back of the TV under a "secret" panel.

Are you sure he used a parallel port?, all the ones I've seen (and used) are either serial or USB - it's been a long time since you could get laptops with parallel ports (or even serial).

If the company ordering them is ordering a sufficient quantity they can usually dictate to the manufacturer as to what features the laptop will have (within reason)

Yes it was parallel - an older laptop used for that purpose and into the parallel port went a circuit board with the cable to the TV.

The engineer did have problems and used a second laptop, this time with an expansion card inserted with a parallel port on the card. Same circuit board into the card and cable to the PC.

What sort of TV was it for?, I've never seen one that used the parallel port - I've also never seen MY Sharp one yet, I'm still waiting for it to arrive, and there's no suggested delivery date

Guess what - Sharp LC32AD5E!
The PC used a parallel port because the cable to the TV was connected by a circuit board terminating in a parallel port. I do not believe that this is the only way to connect to update the software. In any case I have noticed no differences since the update.

There are various methods for updating a Sharp LC32AD5E, first is the system software - this is normally done via a serial lead that plugs in the mini-DIN socket on the rear of the set, and uses an adaptor you buy from Sharp, that connects to a standard serial cable.

There is also an I2C method, possibly he was using some old type of I2C adaptor?, presumably not one obtained from Sharp?.

Upgrading the Freeeview software is an entirely different method, and requires the (currently unavailable) interface from Sharp, which is presumably USB? (the ones I've seen used are).

I let the engineer deal with the update - I only observed what I mentioned previously.

My "speaker" vibration is back again at certain frequencies and another visit from the engineer is tomorrow. I say "speaker" because it may be some part of the casing or other components actually vibrating.
