I believe my grandson turned the brightness down until there is no picture, but I can't see the menu to bring the brightness back up. Can anyone walk me thru the menu so I can see it that is the problem. I change the channel and lower or raise the voice, but have no picture. I did buy a new adapter on e-bay. With the old adapter I got nothing, so I bought a new one.

Re: No picture on Phillips 20in TV
Your previous adaptor may have been damaged by the failure of an internal component in the set.
Look at your LCD screen from a shallow angle to see if you can spot any 'ghostly' images on the screen when it is turned on and has audio present.
If you can, then either the fluorescent backlight has failed or the circuit that produces its high voltage.
I've yet to see a modern set that even allows the brightness to be turned down so far that no image is present.
Your grandson may be 'off the hook.'

In the menu system there is a reset (I believe it's all reset, or reset all...something like that) which should fix the issue.If not, leave the TV unplugged for 4 hours and plug it back in then turn it on.
You can adjust the brightness control on your 19PR19 Philips Tv. For that you have to go to picture contol menu
Do it as follows
To adjust your TVs picture control, select a channel and follow these steps.
 Press the Menu Button on the remote control to display onscreen menu.
 Press Cursor up or Cursor Down button until the word Brightness is hilighted. For each press of Cursor Up or Cursor Down button you can go through Colour, Picture, Sharpness, Tint, Colour temp etc, depending on the adjustment you want to make.
 Press Cursor right or Cursor Left buttons to increase or decrese the selected option. Ok.
yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!
Pressing the menu button will bring up the picture menu. This will show you the options for brightness. If turning this up doesn't fix the problem, the TV will need to be repaired.

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.
By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
I had the same problem with my TV when I purchased it used. Select the input you are having troubles with and enter "Service Mode" by pressing and holding the "VOL - " button and "CHAN + " buttons on the TV, simultaneously until the screen flashes red one time.
At this point you will be in service mode. Pressing the "MENU" button will open a service menu, which is different from the typical user menu. From the service menu you can further adjust your image settings until you have a decent picture.
Initially my VGA input looked terribly bright and washed out. Now it looks incredible!
If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.
i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box.
Switch on the TV.
Set the channel to normal tuner channel 3 or HD input.
Turn off the cable HD box.
Press the Menu Button on the Cable box or the remote.
You should see a Menu.
Use the cursor keys to navigate
The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change.
The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop.
Hope it helps.
