Technika 32-270 LCD TV won't stop scanning

I've had the TV for around 4 weeks. I tuned in all the stations, although it is mostly used for my pc via a VGA cable. Turned it on today and was greeted with a black screen and the message 'do not power off'. It now continuously tries to scan, but every time it reaches 64% it starts scanning again. Both the remote and buttons on the TV are unresponsive. Any ideas of what the problem could be?

Try unplugging the aerial while the tv is off, then turning it on.
Plug the aerial back in when the tv is on, then re-tune.

Im currently in the process of doing this myself hope it works...

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

SOURCE: TV was playing, then the screen turned black.

If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel

SOURCE: LG 42LG30 TV will not scan in DTV stations

Sounds like you're having a problem with your main board assembly. The main board is what processes all your audio/video signals. So if it's not scanning DTV you've probably got a bad card. Call LG's customer support line at 1-800-243-0000 and have them schedule you a service call. Request a DMST if there's one available in your area as they actually work for the factory. Otherwise you may get an ASC(authorized service center) which can be less than reliable at times when it comes to customer support and satisfaction. 

Remember to have your proof of purchase handy as well as the full model and serial number. And by model number, I don't just mean 42LG30. On the side or back of the unit there will be a manufacturer's code. The first part is indeed the model#. However, it will appear something along these lines:
42LG30-UA.AUSRMJR or something similar to that. 

Have that ready definately. Any tech worth their salt will call you a few days beforehand to try to get that data so they can order boards before coming out there, saving them, and you, an extra trip when they have to come and order boards. Without that extended manufacturer's code, LG techs have a hard time with a lot of models trying to order parts as different revision codes and such use slightly different circuit boards.

Computer screen messed up after connecting to a Projector.


Sounds like your screen resolution has gotten changed. Plug your VGA cable in and reset it to 1024x768. Then with the laptop on remove the VGA cable. When you connect your laptop to other devices like that, make sure you are not setting the resolution to the same as the TV.

TV does not autotune to all stations and does not store stations


The set has a EPROM somewhere that stores that info--either a stand alone one or one incorporated into the microprocessor the set uses.

The tuner if bad likely will not cause it to "forget" stored channels.

A possible way AROUND this would be the use of a cable/sat box connected to rear inputs on the set---you would sit on that input and change channels via the box which can usually be programmed to skip up/down channels you do not want---straight around the issue.

I can't connect my xbox360 to my sony pfm-42b2 tv


Keep in mind that your Sony IS NOT A TV, but a monitor instead. There is an actual XBOX360 VGA adapter that's available at most gaming retailers. It was initially designed for those who wanted to use their PC monitors for there console gaming. HDMI is NOT compatible with a VGA input as HDMI is a digital signal type and VGA is an analog type connection. You must also remember to have the XBOX set to a NON-progressive resolution (480i) if trying to hook it up using the standard XBOX video cables.

I have a inspiron1300,and i wondered if it is possibe to connect it to my philips hdready tv.am sure which cable to use


You never mentioned what model Philips TV you have, however I've researched several and most seem to have a VGA video port in the back of them. If you have one of these (15 pin D connector) on the back of your TV you should be able to purchase a corresponding VGA cable (you'll want female pins on one side of the cable and male pins on the other side) and plug one side into the VGA port on your laptop and the other cable into the TV. Then use your TV remote to select that input. Should work fine!
See item 8 in the attached user guide link to see what I'm talking about. http://download.p4c.philips.com/files/4/42pfl3403_98/42pfl3403_98_qsg_eng.pdf

How we can connect pc to tv


Hi
I'm writing this post on how to connect your PC or computer to a TV because last week I returned from a trip in India and wanted to show all of my pictures and videos to my family from my laptop onto our HDTV, but unfortunately I did not have the correct cords and so after fumbling around for 30 minutes trying to connect my computer to the TV, I had to tell everyone that they would have to wait till the next weekend! Pretty annoying considering the times we live in, it should be quite easy to connect the two together!
So here's a quick walk-through of all the methods that I know (if you know any more, please comment) to connect a laptop or PC to your TV:

1. S-Video - This is probably the most common method out there currently because an S-Video cable is cheap as heck and just about every TV under the sun has a S-Video port. You'll have to make sure you laptop is equipped with this port. Remember, there are two types of S-Video cables: 4-pin and 7-pin. Most laptops and PC's are equipped with a 7-pin port, so if your TV only has a 4-pin S-Video port, then this method will not work.
2. VGA - If you have a HDTV, then you will be better off connecting using a VGA cable. It gives much better quality than S-Video and as with S-Video, the cable is very cheap. You usually won't find a VGA port on regular TV's though, so this option is if you have an HDTV.
3. DVI - DVI stands for Digital Visual Interface with "digital" being the key word there. The digital signal will give a higher quality picture than either S-Video or VGA. Of course, your computer will need to have a DVI connection and your TV will need to be an HDTV. This cord is definitely not cheap, it ranges anywhere from $40 to $80.
4. HDMI - Using HDMI will give you the best quality by far. No computers that I know of yet have HDMI ports, but you can get a DVI to HDMI cable to connect it to your HDTV. HDMI is compatible with DVI.
5. Scan Converter Box - This is the last method that I could think of and it involves using a scan converter box, which takes a VGA signal and converts it into S-Video or component video.
Here's a graphic I created with some pictures of the various cables:

Hope this helps someone! If you have any other ideas or suggestions, please feel free to comment!!! Thanks!

The screen is black and a little box that says no signal is moving around on the screen


Check your inputs. The no signal box means exactly that - there's no incoming signal for the TV to decode. So you've either disconnected a cable somewhere or turned off your input device.
Try changing the inputs on the TV (this will be a button saying input or A/V)
Try changing the channels
Check that your cables are correctly connected and that whatever you are trying to use (dvd player, PS3, etc) is turned on.
Check that your TV is tuned to the corresponding input it is plugged in to (if you plugged your DVD player into HDMI input 8, tune your TV to input 8)
Hope this helps.
