Sanyo DP42849 - HDMI Doesn't Work

Re: Sanyo DP42849 - HDMI Doesn't Work

For future reference - the Sanyo GXBM works the menu and other general functions for this TV. I suspect that any remote that looks similar to the GXBM will also work.

TV looks and sounds pretty amazing. Very impressed with it. Especially the sound and general lack of input delay, which is very surprising for such an old TV.

Thanks everyone.

Re: Sanyo DP42849 - HDMI Doesn't Work

Ahhh, you're probably right, Tom.

In any case, I picked up a new board on the cheap yesterday and now the TV is working as it should. I just have to figure out which remote to get for it that will actually work for the menus.

I have the old board if anyone wants it for parts or a test board.

Re: Sanyo DP42849 - HDMI Doesn't Work

Just a note--settings will be stored in non volatile memory (eeprom) so unplugging it for months won't make any difference.

It's more likely than anything else that the surge damage killed the HDMI receiver too. Often the surge current will pass thru a cable box and out HDMI to destroy connected TV's.

Amazingly i've never had a surge damaged TV out of nearly 100... Think it's more of a us problem

Re: Sanyo DP42849 - HDMI Doesn't Work

when troubleshooting in electronics, one of the first things you should try is resetting the device by to factory setting, then check to see if that resolve the problem. Then you try other thing like, another cable or another video source. Then you go inside unit if the problem isn't resolve.

I'm not 100% convince your HDMI ports are bad. does the main cpu chip get extremely hot if you plug in the HDMI cable?

This TV sat for months and months with no power (or power board). I'd be very surprised if it is operating under anything other than factory settings.

There's no need to try another cable or video source - the XBOX works fine with my LED TV, so the cable and source are working.

I can't imagine there being any setting in the TV menu that would disable all HDMI ports. And even if there were - again, the TV has been sitting for months unplugged, surely it has reverted to default settings by now.

If anyone has a board for this TV, let me know, thanks.

The HDMI is bad. If the chip is not replaceable, then I'll have to find another board.

I'm probably not going to spend money on a remote until I get the HDMI fixed. There are loads of Sanyo remotes that look alike but have different model numbers and functions, so finding one that will work correctly is going to be a hassle.

Will the HDMI picture quality be about the same on this TV as it is for the newer TVs? I'm asking because I've been using component, and while watching Cosmos I noticed pixelation in the black/dark areas. Is that normal for component?

SlickClick please get back with me on that board. I need an N7AE. THank you!

Re: Sanyo DP42849 - HDMI Doesn't Work

The TVs HDMI portion in the chip is shot... I might actually have a mainboard laying around for that unit too... how well it works i dont know i bought the unit for the LCD screen... I will have to get the part # off it to check it...

To end the xbox argument; Older versions of xbox known as the "PHAT" models have the fans that blow out the back of the unit; "SLIM" versions have the Fan out the Top of the unit...
If you have a "PHAT" model; HDMI and other inputs is not exactly "automatic" at all... The composite cable has a switch on it physically to switch between HD and SD video display; which means that to trigger the HD function of the ANA/HANA chip it is done externally by that switch. Now I have for hand on fact have an Xbox that when on SD using RCA the xbox works fine as soon as you switch it over to HD it throws 3 rings of death... This concludes that HD is for fact controlled by that external switch where that cable is being used... Now when you remove the A/V cable and switch it for lets say a VGA one the xbox sense that connector in there and allows for very high resolution selections for monitor type displays... Now early versions of xbox do not even have an HDMI port so the older models that do its sort of a pigback on so when you plug in an HDMI cable it basically triggers a signal electronically that an HDMI cable is inserted and activates that line on the HANA chip thus giving signal to the HDMI port; however it will NOT readjust the resolution automatically...

The newer "SLIM" version of xbox only allows for one cord or the other -A/V bung or HDMI- plugged into it at one time and does automatically recognize what type of input and resolution...

So in the end the xbox question is a YES and a NO depending on if its PHAT or SLIM...

Re: Sanyo DP42849 - HDMI Doesn't Work

Do you buy the original remote controller?

are there any components on the bottom side of the main board near the HDMI ports?

to concluded: you try two known working devices: XBOX and a DVD player using the HDMI ports on those unit and still not video? right?

The HDMI is being feed directly to the CPU,so it is possible is could be non functional. possible bad main board.

Re: Sanyo DP42849 - HDMI Doesn't Work

Hmm looks like all HDMI goes into the xilleon processor.. Which is not replaceable. :-(

Re: Sanyo DP42849 - HDMI Doesn't Work

Think the HDMI chip is buried under the shield, which I hope comes off with some screws...

Finally found some time to mess around with this TV again. The shield does come off easily - here are some photos.

To recap: this is the television that didn't work at all, likely as the result of a power surge. Got it working, but none of the HDMI ports work.

Component works, but it has trouble displaying darker colour saturation without pixelating. Not sure if that's normal for a large TV, or if that's an issue with this particular model, or what.

Any ideas would be helpful, thank you.

Re: Sanyo DP42849 - HDMI Doesn't Work

Thanks for the info. I'll have to try to get a remote off eBay for it. Can't believe they didn't put a menu button on the TV . . .

Re: Sanyo DP42849 - HDMI Doesn't Work

here is a link to your TV user manual, review page 6 and page 18 maybe this will help

page 6 you will need the original remote to reset the tv

page 18 are setting on the HDMI port input

Re: Sanyo DP42849 - HDMI Doesn't Work

I remember resetting my a friend xbox because he will travel from one house using HDMI and then at his house he was using composite input. the xbox didn't switch automatically between the two outputs

That's abnormal behaviour. By design, the 360 will automatically detect what kind of connection is being used. Mine has no trouble switching automatically between an SD and an HD connection on its own.

Thanks for the information. That just resets the resolution, tho.

There's no menu button on the television.

Re: Sanyo DP42849 - HDMI Doesn't Work

Thanks for the replies guys. Here's how the Xbox 360 handles video output: If HDMI is hooked up and working, it will show a picture. It might look like crap if the console is not set to 720/1080, but it will still show something. Unlike a TV where one needs to select either component or composite via menu, the output selection on the 360 is automatically detected. Just the quality of the picture is manually changed.

360 works fine on other HDTV.

. . . I have no idea how to reset the TV other than unplugging and holding power button, which doesn't work

Thanks!

Resetting your TV to factory can be done from the "MENU" function on the TV. you have to browse through the menu to find it.

I found this on the web:
Reset the console display settings (xbox)

If the display problem is still not resolved, reset the display settings of your console. Here's how:

Remove any discs from the disc tray.
Turn off the console.
Turn on the console.

Note If you are using an Xbox 360 Wireless Controller, turn on the console by using the Guide button on the controller. Make sure that you use the player 1 controller when you do this. The player 1 controller will have the upper-left light illuminated.
As the console starts, on the controller, press and hold Y while pulling the right trigger. The display settings are reset to the default settings, and then the console automatically restarts.

Re: Sanyo DP42849 - HDMI Doesn't Work

I agree that HDMI is NOT a "hot swappable" thing to try and do... I have seen several HDMIs on TVs go unusable for awhile then later work again but eventually the port fried out on those unit cause they didnt listen and now have to use component...

I also tinker with xboxes on the side; depending on the model of the xbox unit there can be an issue with the HDMI port itself; does the HDMI on the xbox work on another tvs HDMI..?

If the xbox works on other TVs than the HDMI chip or port can be shot on the mainboard of the TV...

Re: Sanyo DP42849 - HDMI Doesn't Work

Hi might sound stupid but has your xbox been connected to a tv by its composite cable ? if so it will not output hdmi and you will need to plug it in via composite cable and change output to hdmi. Sorry I don't want to state the obvious but spent hours on my sons xbox and that was the problem

that doesn't sound stupid, that is a good possibility. there is way to reset the xbox by hold some buttons. Also I will reset everything on the TV from the TV menu function.

Yeah, I'm just hoping only screws, not solder...
