Time for a replacement bulb.

If you feel ok replacing the the bulb yourself, they are available on the internet at a good cost.

If you don't, bring it into a service center near you. They normaly charge around $100-$200 to replace the bulb.

I have noticed the screen is now not as bright as it use to be, still works just not bright. A darker look is the best way to describe it


Hi,

The most common indications of a weak bulb in a Sony LCD Rear Projection TV are:
  • Dimimage with low brightness and contrast.
  • NoPicture, Dark Screen.
  • Shadowsin Image, sometimes circular.
  • Intermittent Shutdown.
  • Fluctuating or Flashing Brightness.
  • Longerthan Normal starting time.
Also check for distortion caused by Optical Engine Failure. If any of these faults are present, bulb will not fix. Sony Optical Engine Fault Gallery

Darker screen after replacing a samsung dlp lamp


DID YOU USE THE FOLLOWING LAMP
BP96-00826A (PHILIPS WRITTEN ON THE LAMP)? ALSO PLEASE CHECK THAT THE LAMP IS COMPLETELY SEATED OR IT WILL RESULT IN BRIGHTNESS ISSUES. THERE WAS ONE THAT I REPLACED THE LAMP IN AND I NOTICED THAT THE DIAL OPENING ON THE LAMP HOUSING WAS A BIT SMALL AND WOULD NOT ALLOW THE COMPLETE SEATING OF THE LAMP AND I HAD A DARK PICTURE AS A RESULT. I USED MY CORDLESS DRILL WITH THE PHILIPS HEAD STILL ATTACHED AND REAMED THE HOLE LARGER AND IT SOLVED THE PROBLEM.
HOPE THIS HELPS.

Blue lines that surround a face or broken lines across the screen


Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Screen getting dark


If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it

Dark band on left side, Samsung HL-R5668W


the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)
