Turning on the tv the picture is small and distorted and sound is not functioning correctly. takes about 20 minutes or so for tv screen and sound to function properly.during commercials mostly the picture shrinks and gets larger. during commercials mostly the picture shrinks and gets larger.

You need to replace the DLP chip in the TV. The whine may be coming from the cooling fan for the light.

If you can darken the room when first turn set on and have sound, take a small light (flashlight) and examine the screen, DO YOU see a faint image of the picture on the sets screen?

Most use a back light and it may not be coming on correctly.

Hi,
Replace lcd panel to solve tv problem.
Thanks.

Hello,

The reason your television is having distorted vision and screen going black with sound is because there is a problem inside the unit. This problem could be caused by either a bad lamp or a faulty t-com board.

My best bet is the lamp, because it is when the lamp start developing any fault it begins the distorted screen thing and coming up black.

What you hsve to do is to get a replacement lamp, open up the television and replace the lamp with a new one, after doing that your television will be in good condition once again.

Take care and good luck

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Rear projection hdtv, most likely damaged tubes. Don't repair this by your self get a tv repair man to do it before you injure your self.

This is the picture tube. If you check shops you can find one that has a picture tube restorer. If they run just the cleaning process it will buy you some time. This is good some times for up to a year

Yes if you could give me a model #, it is probably a diode shorted in pincushion area, or a capacitor.

Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
