try replacing the lamp.

Interesting problem. Get yourself a Canadian Tax Consultant

Could be a bad blue TUBE. Samsung tubes were NOT too good.

Check all the coax cable fittings by moving each with set on---you are looking for a loose shield connection (outer one to connections) that can with ease cause this problem.

lamp and color wheel do both fail on these sets, what is your specific question?

If you here a whining sound when it is trying to turn on, then your colorwheel is bad and needs to be replaced.

okay that sounds like a problem in the horizontal circuit and vertical circuit.the module of those section wants to be replaced.only a tech can do the repair.look for a tech to repair your tv

After the timer light blinks for a while say a few minutes do any other LEDs start blinking along with it? Please provide this info so that I can help you with your problem.

Sai.

I believe you have an issue with the CRTon this set, it is a common one and not that expensive of a part to replace, around $80.00
This is the color gun that atatches to the lamp.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) 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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
• 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.

need replace convergence ic chips to resolve this issue, parts cost about $40

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.

Solution #2


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

Hi,
You can confirm new convergence issue cause by installing old audio-video board back and also check all connectors are plugged properly in respective jacks in circuit board.
Can you post wavy lines screen image here to diagnose its possible cause?
That will give me better idea to diagnose problem.
Thanks.

Can you please upload an image to imageshack.us and get me the link so that I can see for myself what it looks like?

Usually when I see this set with an unusual problem the first thing I do is to remove the front cover and look for coolant leaking onto the circuit board. The coolant is in a small chamber above each picture tube and sometimes the gaskets lose their seal and it begins to drip down onto the circuitry. Get a powerful light and inspect it closely for a few drips coming from the frame around the picture tubes and look for small puddles of goop on the boards. The only other common problem I run into on this set is convergence issues which usually cause a dead set or color alignment problems when set is on. I really think whoever looks will find coolant leaks. Good Luck, Russmann.

Timer light usually starts blinking if there is a problem with the vent. Take of the back cover and empty a can of compressed air on it(the cover) so that it will be un-clogged. Put it back and turn it on.Let me know if problem persists so that we can continue troubleshooting.
