The RGB is messed up, specifically the red. It goes out of alignment. If you hit the bottom of the TV. It will temporarily go back into alignment but it usually doesn't last.

Best is to open the set and realign possibly with the pattern screen for picture , colour alignment.
Do it with care and set the corrections coarsely , then to fine trimings to have a good focus and aspect.

How to reset nokia mobiles life timer to ''0''


Nokia life timer is a counter that keeps track of the Total call time of your phone. It will show how much the phone has been used, and it?s the best thing to check if you?re planning to buy a used Nokia Mobile.
To see the Total Call Time or the life timer counter, On the standby screen type the following code *#92702689# (Easy way to remember this is ? *#war0anty#). And it will pop up a message that shows the life timer in hours and minutes.

Here is a detailed procedure to make this life timer zero.


REQUIREMENTS:
The following files are required to reset the life timer:
  1. Nemesis service suite link: Download from Here
  2. lifetimer.pm file: Download Here
PROCEDURE:
1. Download and Extract the lifetimer.pm file, and Download Nemesis Service Suite.

2. Install Nemesis Service Suite on your Computer, It won?t take much time.(select the first option)

3. Install Nokia Cable Drivers (No need to install, if you have Nokia PC Suite already installed)

4. Connect The Phone in ?PC Suite? Mode to the PC

5. Open Nemesis Service Software

6. Click on ?Scan for new Device? Button on Top right Corner 



7. It Will take a few seconds to scan, and it will load up the software interface after communicating with the Phone.

8. Click the ?Phone Info? Button.


9. On the Bottom, Select and open the ?Permanent Memory? Tab, which is next to the Fbus info.


10. Click the ?Write? button on Below right, and open the Extracted lifetimer.pm file on your PC. 


11. After the lifetimer.pm file is opened , it will immediately start writing it to the Phone?s EEPROM Area.

I cant keep my tv turned on after i pushed the rgb button by mistake it keeps on displaying no signal and then it goes off


Turn on the TV again. You need to change the input from RGB back to cable or HDMI or Component or whatever input you have a source for. If you don't know which one, look at the back of the TV and the wires you've got plugged into it.
If it's 1 round coaxial cable, change the input to Cable.
If it's three wires (red, white, and yellow) change the input to A/V.
If it's 5 multicolored wires, change the input to Component.
If it's an HDMI cable, change input to HDMI.
If you cannot change the input before the TV turns itself off, try unplugging the TV from the wall socket for about 10 seconds, and then plugging it back in. If its still on RGB, you're going to have to either find a way to get faster at switching inputs, or find an RGB cable and something to connect it to your TV. This is a last resort however.

How to turn on rgb from lap top to tv.


In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Red and blue convergence wont line up. What should i do.


convergance can be tricky and you should follow a manufacturers proceedure from a manual.

most specificaly start with the green H and V Linearity and center , then the Red and Blue

Projection TV's and Component Video RGB have their Horizontal and Vertical Sync signals on the Green Component..

There may be other reasons for their specific order of operations within a calabration proceedure such as your 'RGB convergance alignment'

Philips Projection Screen TV Model PTV915 Horizontal Alignment


Problem solved, needed to get the universal remote i was using set up with the proper code. Once I did that I was able to use the remote to set up the single & multi-zone Red & Blue Alignment.  I also pulled the back plate off and manually adjusted the RGB focus knobs. It seems to be working just fine now.
Thanks to all the other posts.

G2 alignments?


Hello YankeeTwidgt,

Here we go you will need a schematic diagram (You may already have one but I thought I would mention it ), an oscilloscope, a TV signal generator (NTSC color bar, RGB purity screens, and pattern screen), and a voltmeter (I would prefer you have a VTVM, but a digital meter with high impedance (>=10M) will be ok).

First turn all of the color and tint controls completely down (This includes the main color and tint and the pre-amp color controls if you have access to them).

Then turn the RGB pots fully counterclockwise.

Once this is done connect the signal generator set to channel 3, and set to the specifications on the schematic, use the color bars, what you should see at this point are bars of various shades of gray.

Then turn the generator to the purity setting and set the pattern to red.

Once this is done your screen should be dark or dark red, gradually adjust the R pot until the screen is pure red and the voltages, and signals match what is seen in the schematic (mark this point on the pot and the return the pot to fully counterclockwise).

Do the same for the Blue and Green Controls (Blue first and then Green).

Once all of the pots are marked and turned to counterclockwise, set the pattern to gray purity, and turn the pots back up to their marked positions, the screen should be gray. switch to color bars and the screen should have the proper colors.

This is a course adjustment, and you will have to do a fine adjustment using the schematic, and the test tools, but this will put you way into the ball park.

The reason these pots are not talked about in gray scale adjustments is because they usually don't have to be touched. That's why it is important to get them back to specification using the voltmeter and oscilloscope to set the signals up properly.


I wish you success,
