Colors in left upper corner like a rainbow and fuzzy warped picture with lines that will run thru the picture from time to time, majic focus does not clear this up and I can not get the color set...

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common 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.

50" hitachi 10 years old has blue and green colors

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( 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 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.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, 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.

Philips 55P8288A tv has a dull color and a red hue.

This sounds Like the the coolant for your piture tube has become cloudy and needs replacement (usually blue or green tube - thats why the image seems ovrely red).It's a big job (labour wise) since completee dissassembly is required ($200-300). It can be done youreself - check out TVrepairkits.com to get the coolant and instructions.
You can confirm that this is the problem by dissassembling the unit to the point where you can view the face of the CRT's (red green and blue) directly.

Color problems

You have a defective light engine and Hitachi will replace the part. Here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. At first, they will act like they've not heard about this problem but they will give you the names of some certified dealers in your area to have come out and take a look. Once the tech comes out and confirms that it's a defective light engine, call Hitachi back at the same 800# and they will send a brand new light engine directly to the dealer and Hitachi will pay for it ($1500).

Here's the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty they will cover the expensive part but not the install. Our install was $400 but other on this site have paid around $200. Please do not let anyone tell you that you have to pay for this part. Hitachi has not recalled the part but they are replacing it with a brand new light engine for free. Also, deal only with Hitachi's customer realtions and not regular customer service. Good Luck!

You have a defective light engine and Hitachi is aware of it. Here's what you need to do...recently went through this. Call Hitachis customer relations department at 800-654-7013 and tell them you have a defective light engine. At first, they will act like they've not heard of this problem but they are all too familiar with it. They will give you the names of some certified dealers in your area. Once the tech comes out and confirms the problem, call Hitachi back at the 800 # I listed and they will call and confirm with the dealer that you have a bad light engine. They will send a brand new light engine to the dealer (Hitachi will cover the cost $1500) and the dealer will call you to come out and install.

Here's the kicker, if you're not still under warranty, Hitachi will cover the expensive part but you will have to pay the install. Our install was $400 but others on this site have paid around $200. If you're still under warranty, Hitachi will cover the part and install.

Please do not let any dealer tell you that you have to pay for this part. Hitachi has not recalled this part but they are replacing it to you for free...you just pay the install. Also, deal only with their customer relations at the 800# I listed.Good Luck:)
