This can be as simple as poor connections on the convergence ICs or defective ICs. If you can solder you should be able to repair this yourself. Please let me know if you wish to attempt the repair and I will provide additional details and instructions.

Thanks,
Dan

My sansui rear projection tv's picture is concave with convergence problem also how can i fix it


The convergence can become unstable if you have a failing colour wheel if a dlp set. the same thing can happen if your lamps is beginning to fail the poor frequency of light from bulb disrupts picture. Convergence is usually done by entering service technician code into set through the remote and entering the engineering sub menu and if you don't know what your doing or have a colour pattern generator you could make things considerably worse .

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

I bought a Sony DSC t700 approximately 6 months


If the built-in flash does not function, then the camera may be set to Auto and will only flash when taking pictures in poorly illuminated environments.
To set the camera to the Forced flash setting so it will flash regardless of the surrounding brightness, press the UP ARROW on the control button until a lightning bolt icon appears on the LCD screen.

If the Forced flash setting is already enabled and the flash is still not working, then the issue may be due to another camera setting. Even if the Forced flash setting is enabled, the flash will still not work in the following circumstances:
When shooting MPEG movies
When set to the Twilight mode
If an external flash is connected
If in the Burst or Multi Burst mode

Please touch the MENU option on the screen of the Camera.
Then, select the REC MODE under the MENU.
Then, select NORMAL under the REC MODE.

If you're not able to select the NORMAL under the REC MODE, try Initializing the Camera.

First, please touch the HOME on the LCD screen of the Camera.
Then, select the SETTINGS in the HOME menu.
Then, select the MAIN SETTINGS under the SETTINGS.
Then, select the Initialize under the MAIN SETTINGS.

If the issue still persists after performing the troubleshooting steps provided above service of the Camera is required.

It's required to physically examine the Camera to determine the exact issue at the service center.

No sound


Go into the TV Menu and access the sound settings, for the UK it would normally be set to I. This MAY need to be changed to a different setting. Try the options that are listed. Might fix it!!
