Unable to increase the picture brightness sufficiently using remote control. Can't seem to find any technical info on the Internet so I thought I?d try here before I crack the access panel to ?poke around?.
Tom, Have you also attempted to clean the mirror as well as the inside of the screen? Focus as well as brightness issues can arise due to elements on these components as well. I would imagine you are having trouble with B+ V if this is not the case. Also if you have a HV probe you should get the service manual and check each flyback as well as the individual drives. Not familiar with Panasonic s method of return loop but if the voltages are wrong somewhere it will greatly effect performance of the circuit. Hope this helps. :) I smoke and have to clean mine regularly.

A lot of people don't realize that backlight settings can affect the picture.
Go to the menu (press menu on your remote)
The menu will show picture options. Just toy with different settings until you find what you want. It may be on a preset setting that doesn't work. If you are in a bright room, you will need to increase brightness and contrast and perhaps backlight.
Usually an unclear picture is due to the contrast, backlight, and brightness settings being too low. You can also increase sharpness.
I suggest a contrast setting of 70, a brightness setting of 60-80, and a backlight setting of above 80.
Your problem is that your shutter speed is too low. If your concern is primarily stopping movement (hair or other) you need to increase your shutter speed or use a flash. If you don't wish to use the flash (or it is already too bright), then use the Tv mode on your camera (Shutter Priority) which controls the shutter speed.
The value will vary based on the speed of your object and the amount of light in the scene. I would suggest starting with a value of 1/250 second which will probably be sufficient to freeze most hair movement. Note that as you increase the speed, you need more light.
there are controls in remote by which we can decrease the brightness. u did not mentioned if they are working. try to decrease brightness by pressing the menu of remote & going to picture controls & find brightness control there.
if above function not controlling the brightness of tv, there may be fault in lcd panel of your tv. which may be diagnose only after seeing exact condition of picture.
Make sure the power cord is properly plugged into a wall outlet if your TV is not powering on.
Make sure the video and audio cables connecting your TV to external devices are secure if you are experiencing a fuzzy picture or no picture.
Reset the parental password if you forgot the password and
are unable to view certain programs. To do this, click "Menu" on your
remote control and use the arrow keys to select "Parental Controls."
Enter the master password, which is "4357" to reset the password.
Turn off the caption vision option if you are seeing a large
black box on your screen. To do this, click the "Menu" button and select
"Setup." Select "Caption vision" and press the "Plus" button on your
controller to set the option to "Off."
Check the "TV/Video" setting if you're not getting a picture
on your screen. You may have inadvertently selected a video input that
isn't active. Press the "TV/Video" button on your remote to cycle
through video inputs.
Alter the brightness settings if you are experiencing a poor
picture or no picture. To do this, press "Menu" and select "Video."
Increase the brightness settings to see if the picture begins to appear.
Make sure the volume is not muted if you are experiencing a
clear picture but no sound. Press the "Mute" button on the remote
control to turn mute on and off.
Power cycle your Sony
Wega if it's frozen or not responding to your remote control. Unplug
the power cord and wait a few seconds. Plug the power cord back in.
Remove back fron tv locate line flyback transformer
on this transformer there should be two adjustment controls very carfully adjust the bottom one, do not adjust to far as picture will have fine white lines on it
Hi, before you go any further, did you try to press the brightness control up? because sometimes the remote got stock, it might cause to decrease the brightness, use the control button on the front panel of the TV instead of remote to increase the brightness, if no progress try to shake the Tv if you can, if its a loss connection, you can see the screen flickering and if its the case try to unplug and plug in the wiring connections or call the nearest tech in your place. for more info about tv troubleshooting tips visit www.my.electronicshelponline.com
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.
