Question about NEC Televison & Video

Open Question

I have an NEC NLT-40HDB2 with some odd issues, the input (changing to hdmi/ avi) and channel up buttons don't work even when using a logitech universal remote, the buttons on the side of the set d

Basic run down: I can turn the TV on with the remote, and watch digital tv fine. I can only switch channels using the down key (I have tried using a logitech 525 aswell, still doesn't work) None of the inputs work (avi/ hdmi/ vga) I've opened the set and didn't notice any buldging caps, or anything out of the normal. It appears to me the set has been locked, I've had a read though the manual for this TV and it doesn't mention anything about lock codes/ or service menu. Any ideas would be great!

SOURCE: TV freezes when switching to a digital channel

Issue was with the HD channels only.
Updated the firmware of the TV to ver 2.

Now the TV will stutter for a second when changing to a HD channel but it no longer locks up.

SOURCE: TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

Firstly, CAN??, and then how do I get an NEC NLT-19XT1 television to work with a TEAC High Definition Digital Receiver HDB848 HDMI, please. Anyone know how? Appreciate all the help I can get. Thank


Id the TV Anolog or Digital? If it is analog, then the digital receiver must have RCA outputs to meet the TV's RCA inputs. To make an old analog TV work (meaning getting a picture), you have to check id the receiver has RCA or S-Video outputs. If so, then connect an RCA cable with yellow into yellow, red into red and white into white and then connect the same colors plugs to the yellow, red and white to the RCA inputs of the TV. Or, you can connect a S-Video cable plugs in the output of the receiver and the input of the TV, disconnect the yellow RCA plugs at both the receiver and TV sockets and leave the red and white cable for sound only, as S-Video has an improved video signal, therefore better picture quality. On the TV you have to select an AV input channel, like AV1 or AV2, etc. The same channels that you had used when you were once watching VCR tapes on analog TV. Hope this helps.

How to retune a tv


Whether you have a remote or not, you'll need to access a menu screen and figure out how to use the volume buttons or channel buttons to highlight the scan for channels section and allow the TV to scan to pickup or drop channels.

It's usually somewhat self-explanatory once you've accessed the menu.

HDMI cables are actually wonderfully simple to connect. Once you have connected one end to the TV and one end to the DVD player, you will simply need to change your input channel using your TV's remote. Find a Input or Video source button and press it until the screen says HDMI. Now your TV may have several HDMI ports so you may have to try a couple HDMI channels before you find the right one.

Hope that helps!

Tv won't switch to "tv"


Your T.V. is programmed to store the last input you've selected. You have to manually switch it back to your T.V. channel input after each time you switch it to HDMI or any other input even when you turn it off. The "Source" or "Input" button on your original T.V. remote will change this.

I have a visco TV and I cannot get it off of channel 1. The remote does not work so I bought a universal remote but it still won't work. I tried to codes for NEC and Polariod as suggested by others,...


There should be channel buttons on the TV itself, try using those. Also, you may want to try changing the input from the Cable Box. 
I am curious as to why the remotes don't work. Also, how did it get onto channel one. Did you get the TV used?
Here is a link to the AV Science Forum. It seems other people have challenges with this TV as well.

Hi I have a 32 inch hd vizio tv and a ps3 system and I bought s Belkin hdmi audio and video cable and I'm trying to figure out how connect the cable to the tv and ps3 to get hd channels and hd games and...


Cable: First you need to be using an HD Cable box to get the HD channels that your provider offers. if you don't, you can't get HD channels. Keep in mind that not all of the channels that your provider offers are in HD. Out of the 300+ channels that my provider Cox Communications in Las Vegas offers, they offer 91 of them in HD. If you have an HD box, you need to go into the settings menu and make sure that your video output is set to constant as you do not want it bouncing between different resolutions when you change channels. In your case you will have two options, 720p and 1080i (1080p does not exist for cable due to the amount of bandwidth required). Choose 720p because your set is under 40" and you won't see a a difference between 720p and 1080i except for that because it's progressive, HD may actually look better. (NOTE: although your analog channels will display at 720p, they are not in HD. They are simply up converted SD so don't expect that they will look like HD channels.) Also be sure to set your audio settings on your box to "HDMI out."
In general, HDMI devices should automatically detect HDMI input but since I don't know what kind of box you are using, it is possible that HDMI-out is disabled in the settings. My box (Scientific Atlanta) doesn't have that option, but I don't know about others. As far as the set is concerned, plug the HDMI cable into the input you want to use (if it's a new Vizio, I'm assuming there are three inputs as that's what my 32" Vizio in the kids' room has) and the set will auto-detect the HDMI input and automatically set the resolution accordingly.
SIDE NOTE: The only other way you're going to get HD channels from cable without a box is if you're using your COAX cable directly in to the TV and that is only if your cable provider has them floating on the line and you're only going to get the 5 major networks and Univision in HD.
PS3: This is even easier. WIth your PS3 powered off and your TV powered on, connect one end of your HDMI cable to the HDMI out on the PS3 and the other end to the appropriate HDMI input on your TV (of your choosing). Power on your PS3. Your TV will automatically detect the HDMI input from the PS3 and put that HDMI input on the screen. You will get an on-screen message from the PS3 detecting HDMI and it will ask you if you want o use HDMI or words to that effect (I can't remember the exact message... it's been a while). Choose "yes" and it will adjust the picture accordingly and should automatically choose the highest video resolution your television can display. To verify your settings, first hit the "guide" button on your Vizio remote control and in the upper right corner it will tell you at exactly what resolution it is displaying at. If it's not where you want it to be, on your PS3, go the Settings Menu and scroll down to "Display Settings" and the first item on the list is "Video Output Settings." Follow the step by step on screen menu prompts to determine your display settings, and choose "automatic" when prompted. If everything is copasedic, the highest resolution your television can display at will be listed at the top (and will be the current setting) and all of the other resolutions will be listed below it. If something is wrong between the "handshake" between the HDMI from the PS3 to the TV and it doesn't display in HD, go back into Video Output Settings" and when prompted, choose manual in stead and set the resolution on the PS3 the highest your TV can display. NOTE: Most 32" TV's have a maximum resolution of 720p fir the reasons I stated earlier. Check your manual for the specifics on yours. Furthermore, all PS3 games are in 720p so even if you have a 1080p TV, don't expect higher resolutions than that. AS far as Netflix is concerned, not all of their programming is in HD. The scale for Netflix is SD/Low/Medium/High/X-High. HD/Low/Medium/High/X-High, your quality depends on the program and strength of your Internet connection.
Closing: I'm a little confused by your issue as HDMI is automatic and you should automatically be getting HD so the only other thing I can think of is that your display needs calibrating and you just think you aren't getting HD. In order to get the most out of your new TV and your PS3, I would highly recommend that you calibrate your set with a Blu-Ray calibration disc that comes with color filters. It will take you about an hour or so to get the hang of and use correctly but the results will be very noticeable. The presets that come out of the box and the settings that they use on the floor in the store are awful and you don't realize how much you've been missing in picture quality until you calibrate. Do not rent this disc from Netflix as it does not come eith the color filters. You can buy a calibration disc at Amazon. I got the DVE one, from what I understand, the Spears and Munsel one is very good as well.
