The Official HP LC2600N/LC3200N/LC3700 thread - Page 32

post #931 of 1101
Hello all. I've got a problem with my 2600n. Yesterday the picture started going extremely dark and then out. Eventually the screen was unreadable. Adjusting the volume put a yellow bar from the top to the bottom of the screen. Obviously something is really out of whack. I've called HP and they're sending a tech. I was just curious if anyone else had this problem and whether or not it was a fast and warranted repair. THANKS!

PS: I do really like this TV and I have this board to thank for making my decision to buy it...

Can you see the menu if you call it up?
If so, can you adjust the backlight and does it vary the background from black to grey?

PS, welcome to the forums.

videobruce,

I cant even pull up the menu. When it comes up it is nothing but grey bars from top to bottom. I think the "video card" portion of the television is toast.

Try a full reset. It will dump everything I believe (memory wise);

Pwr down,
Unplug for 30 seconds,
Press and hold the top system reset button (w/ ball point pen under RF inputs) while you plug AC cord back in,
Turn set on.

What,s not clear is if the reset button should be still held when you turn the set on w/ the pwr button. Try it either way.

Still no luck...the thing is fried. I'll update after the tech stops by friday. Hopefully I'll be getting a bunch of new parts for $0.
post #936 of 1101
Ok, so the story gets longer. They sent a contractor who replaced all the internal parts...It works great for about 2 hours then dead. I'm convinced its cursed. Tuesday they're sending someone else.

The whole chassis was replaced??

Hi there,

I used to have an ATi Radeon 9800 Pro, and by following the instructions in this thread, I was able to run my LC2600N at 1368x768 successfully and beautifully. But, my video card died and I replaced it with an ATi Radeon X1300. When I follow the same instructions as before, I do NOT get 1:1 mapping; the LCD just says it's in 1280x1024 resolution out of nowhere and the screen becomes small and fuzzy (not razor sharp as before). How can I solve this issue?

Thanks,
Abe

I changed it to the Sony GDM-W900, as described in one of the earlier posts (I think by Rhetoric). Apparently, the monitor already there (Sharp something) could not take the resolution. Any ideas?

I have a hp LC2600N. My kid played with remote control today which has caused me a problem as no display(picture) on screen when I switch input source back to PC from TV. I have to reset pc to get the picture back. any one knows how to get the problem fixed? thanks in advance

Are you using the HDMI for the computer? If so, I believe if you change inputs you loose the handshake with the computer.

Thank you for your reply, videobruce. I use DVI for the connection. the last try I did was reset the TV back to factory setting, but the problem remains. I used to be able switch between the inputs freely, now when I switch input PC (with display) to TV then back to PC again, PC has no display and the menu indicates no input signal. TV input has no problem.
post #945 of 1101
That's one up on me since if I switch off of the HDMI input I can't get it to handshake unless I re-boot the PC. I just wrote it off to one more 'glitch' in ther firmware.

Anyone else have something on this.

Does anybody know if there are discrete remote codes for video inputs for these models? I wouldn't have thought so since the remote doesn't have any buttons other than the one for scrolling through the different inputs, but I found this thread in another site:
http://www.remotecentral.com/cgi-bin...read.cgi?26680
that has a link to a remote code file for Pronto remotes. I don't have Pronto remote, nor Pocket PC to emulate it, so I couldn't try the remote codes, but I looked at it using ProntoEdit application, and it has buttons for "TV" "AV1" "AV2" "HDMI" "DVI", etc. which seems to indicate that it is programmed with discrete input codes, and the OP indicates that most of the codes work (he doesn't really say which ones).
Does anybody have any additional info on this or verify that those work? It would really be helpful to have discrete input codes for programming macros on my universal remote.

Thanks.
post #947 of 1101
I feel a bit like I'm talking to myself, since I'm answering my own question, but hopefully, some people will find this useful. I recently discovered that despite the lack of buttons that come with these TV's, they do have discrete input codes. So if you have programmable remote control, you can assign buttons to go directly to any of the input ports without having to scroll through the list. More usefully, they can be used to include input selection in macros on the remote contol.

If you have the newer Pronto remotes, you can just go to
http://www.remotecentral.com/cgi-bin...hp-tv-2005.zip
and download the file and upload it on to your remote and most of the keys there work. The discrete power on works, but not off key. Others, like HDMI 2 doesn't exist on these TV's, so they don't do anything. The interesting thing is that there are separate buttons for Input 1 composite (AV1), and input 1 component (YPbPr1), and similarly for Input 2. It means you can have both composite and component of INPUT 1 and INPUT 2 connected to devices, and can access either of them via a button on the remote. I don't know if anybody would find having additional composite input useful, but there it is.

If you have some other programmable remote, you can go to:
http://www.remotecentral.com/cgi-bin...&dv=television
to get the codes for the individual keys, but, but the procedure will be different for different remotes. I have the URC-8910, so for those of you with JP1 remote, you can start off with the attached file to create the functions (it's in RM format). The file currently sets L1, L2, L3, L4 to COMPONENT 1 (INPUT1), COMPONENT 2 (INPUT2), HDMI (INPUT4), and DVI (INPUT5), respectively. Also, SHIFT L1, SHIFT L2, and SHIFT L3, is set to VIDEO 1 (INPUT1), VIDEO 2 (INPUT2), and TV. With RemoteMaster application, you can change the key assignment to anything. I hope someone will find this useful.

Hey I have the LC2600N and I cant understand the widescreen set up. I have a xbox 360 and widescreen is perfect on it. And thats on just the stretch aspect(even though that seems like it shouldn't be stretched). When I watch Standard Definition TV, It's also fine on stretch mode. BUT, when I watch DVD's in my DVD player or 360, even widescreen DVD's, I always have the black bars, unless I put it on zoom, and that makes it look like ass.

Now I got a HDTV because I play my xbox alot and I watch alot of movies, but it doesn't seem right that I have those black bars...any suggestions?

Does anyone have experience with the LC3200N and the Nvidia 7600GT graphics card?

I can't get a signal at anything higher than Windows load screen resolution. This happens with both DVI and VGA settings (and corresponding ANALOG and DIGITAL settiings on the input).


---the past---
If I booted up using an extra HP L1925 display and then swapped the cable to the LC3200N, everything used to work fine... I could use Powerstrip to get the LC3200N to run at 1368x768, and just 'suspend' and 'wake' to simulate a normal experience. However, if I tried to boot directly with the LC3200N, I would always get 'no signal' after the Windows load screen.

My desktop is 60Hz.

Any ideas on settings, cables, the 7600Gt card, etc...

HELP!!!!!!!!!!!!

There was a 'trick' with these sets You have to force the TV to 1280x720 or 1366x768 (forgot which) in the TV menu for it to work properly. Read back through the thread.
Are you using PS?

Yeah. I read all those messages earlier this year and have set the TV for the appropriate resolution (1366x768). I've done just about everything I can think of with the TV, so I'm assuming this is problem is between the card, cables and TV.

Oh, and the problem is not power supply related, as I am using a replacement 500W power supply which has allowed the 7600GT to run games like Oblivion at 1366x768 just fine.

Check your Device Manager. Under "Monitors", does it say "Plug and Play Monitor"? If it does, it could be that your computer is confusing the TV with the old monitor you may have had it hooked up to. Try following this post to reinstall a new monitor driver

You can use the attached inf if you want, since the link to "davemon.inf" seems to be down now. It's not exactly the same thing, but it will practically do the same thing. It just sets the max resolution and identifies the monitor with a name.

Thanks!

But sadly, these tactics only work if you can get back to your normal desktop. I'm stuck in SAFE mode (800x600) or VGA mode (640x480). If I try to go to anything else the LC3200N shuts off after telling me there is no signal.

I assume this really means the 'signal' is out of range in terms of refresh rate or resolution.

---

I had problems before, but this latest round started when I tried to go pure DVI from my graphics card to the LC3200N, rather than using VGA adapters on both ends.

Its almost as if the DVI cable (shipped with the LC3200N) somehow told my 7600GT drivers that the display properties had changed ... and now I am locked out of my desktop on all of my LCD panels (just got rid of my CRTs).

Any thoughts?
post #955 of 1101
After reading the manual, it looks pretty ominous re: firewire port. I have firewire out on my camcorder, and would love to hook directly to LC2600n this way - could I in any way damage the monitor if I try it? (dire warnings in manual almost recommend against connecting to firewire!).

Thanks

DVI shouldn't be a problem. I have my computer hooked up to the TV via DVI. When you are in safe mode, change the screen resolution to 640x480 or 800x600 and set the refresh rate to 60Hz and "Apply" the setting, then reboot to normal boot. You should have your desktop at whatever setting you set at safe mode and you can change the setting from there. If you still get a blank screen, uninstalling and reinstalling the video card driver from safe mode might work. When you do get a screen up, and you are custom setting to get native resolution, try 1368x768 if you don't get a good result with 1366x768. For some reason, with my video card (an old Ti4200), I had less trouble with 1368x768, although through DVI it would accept 1366x768 (possible because it just an old card).

You might also try changing the TV setting to "Digital AV" to see if you can at least get a screen to be able to change the setting. It seem to me that digital AV setting was a little more tolerant about the signal it was receiving and would sometimes at least show a screen, even if it was distorted or off to ones side.

Can you go more into detail on how your screen blanks out?

Does your desktop load then blanks out

or


Do you get an "out of range" message after boot ( not seeing desktop at all)

Alternatively,you can go into safe mode and un-install powerstrip and re-install it under normal mode.Also,try holding down SHIFT to prevent any applications loading.I suspect powerstrip is giving you problems ,since you have stated you have access to more then one monitor.

Does anyone know what chipset the LC2600N uses for the tuner?
post #959 of 1101
I get a "no signal detected" message before I even see the desktop, and AFTER I see the Windows loading screen.

When in safe mode GVA, if I try to change the desktop to 800x600x16 (or 32) at 60Hz, I get a "no signal detected." In fact, I can't change the screen to ANYTHING other than the VGA mode...

Actually, the monitor does not actually say 'no signal detected' or 'out of range.' It just gives me a blank setting for resolution (upper right corner) and then goes to sleep.

So it seems like the card/cable is not sending a signal to the monitor. Or at least not a signal the monitor can use. Rebooting after changing the resolution in safe mode VGA does nothing. Same problem.

I think I'll try to reinstall the drivers. Does this really work under safe mode VGA?

Thanks!
