20 Most Recent Samsung HCL473W 47" Rear Projection Television Questions & Answers

This set is prone to convergence issues---someone to know would have to open set and unsolder the convergence chips it uses to see if set will power up with them out of the circuit. They will look something like this but have a different stk number like -020 or 040.

You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Thats usually indicating the ICs have failed. Usually with that model its best to replace the board rather than try replacing the individual components as ther are several 3.9 ohm resistors that will need to be checked and possibly replaced along with both ICs. www.tvcircuitboards.com should have the replacement board for your model if you need one.

Itispossible that the high voltage module went out, and to have it repair you are looking at babout 500, at the lest, and if it was me I just buy a new LCD, prices have really went down.You can good to www.partstore.com and checkand see if they have a highvoltage, deflection module, for your set, Take care.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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.

Here is what to do to confirm what problem is, go to black and white program and make sure color adjustment is turned all the way down to zero.

What you are looking for is what color is the screen?


If it a primary a yellow looking screen (all or most) you have bad Glycol in most likely the blue tube. These sets have a sealed area with a sealed area with Glycol (it is like antifreeze and meant to keep the face of the the three picture tubes cool).

What can happen (usually the blue) is it becomes contaminated with bacteria====note, if blue tube is contaminated you will have yellow screen (red and green=yellow.0

The real easy way to confirm if this is the case is with the back removed and access to the three large lens on top of the tubes look into each lens, if the blue one has no picture and looks like a floodlight, but the red and green have a picture, YOU HAVE FOUND OUT YOUR PROBLEM.

I can tell you if this is the case I can tell you what is involved, this most likely is not a do it yourself repair but i can tell you what is needed.

Hi,

The problem you are experiencing is due to a failure in the convergence section of your set.

If you have some electronics experience, and soldering experience, you can repair this set at home.I can help you.However, it is not the easiest set to work on and definitely not for beginners.so if you don't have any experience I would highly recommend having a shop perform this repair. It typically should range from 200-300 dollars.

If you have experience repairing electronics, then i believe you could do it yourself.

I can talk you through this, But an easier way would be to point you in this direction - This kit is $76.95, and includes full directions, WITH photos included for reference..

If you have a soldering iron, and a screwdriver, I know you can do this!!

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

yes or the green tube is going bad. if it holds solid just a little green, you just need to turn down the screen control for the green drive. if it gets brighter and brighter green until its really intense, suspect bad tube or board.

the green drive knob is hidden in the front, behind the front access panel. its labeled but hard to see, only turn the one know counter clockwise, it will be labeled G and SCREEN, there are 6 knobs

Hi


Thanks for using FixYa. To reset the TV turn it off and wait for 15 minutes. After 15 minutes unplug the television power cord from the electrical outlet and let the television remain without power for more then 1 minute. Plug the power cord back into the electrical outlet. If the television is plugged into a power surge protector, remove it from there and plug it directly into the wall outlet. Turn on the television. If the issue is resolved, then the problem is with the power surge protector and not the television. If the issue is not resolved then this might have happened due to over-voltage. Please check the power supply unit for swollen/ bulged capacitors and burnt wires/components on the power supply board. Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in off condition. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Ur tv have a convergence problems,it dead.The convergence board have 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Ur tv have a convergence problems,it dead.U must know how do soldering,have soldering tools,and have solders to fix convergence problems.U must replaced the 2 STK Convergence ICS,and some or all it resistors on the Convergence board.Tries wesites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors

Call FOX 1-800-227-5369 they have Lamps

You don't need to replace the whole board, regardless of which board it may be mounted on. The STK IC convergence chips alone are all that need to be replaced. You can order them from a number of different online sites. You can try Alibaba.com. If you have any more questions, feel free to ask!
