Replaced convergence ic's and picture is good but still no blue color to adjust in the convergence mode. the blue bulb is lit in back.

You may have pressed a wrong button when in service mode---it allows among other things to turn individual colors off like Blue--to make it easy to adjust red to green first.Also take a look with set on into the Blue lens to make sure you have a image and it does not look like a blue flood light.a last note: if you tampered with the lens (they have a wing nut on side that allows them to be turned you may have on the blue turned the lens so far there is no focus---for that lens--Did you?

Blue green and red not in line. how to solve

Thats a convergence issue which is caused by the convergence amp board needing repair. The samsungs with the P55A chassis such as your model usually require replacing the convergence amp board which is a simple unplug old board and plug in the new one repair.

Is it hard to restore a Samsung HCN4727W tv back

You want to re-align the convergence for this tv correct? It is not hard, you can do it yourself. You really need to get the service manual to do this. Use a good input source for the 480i input and maybe an xbox or blu-ray player to help with verifying alignment for the 1080i input.

Too much to explain here, so search on google for the service manual. You will likely need the original remote for the tv as I think a universal remote will not have all the button you need on it to complete the alignment.

Pop smoke and blurred screen.


The easiest solution would be to go to http://www.servicemanuals.net and purchase a downloadable service manual for about $16 US. If you plan on working on this unit in the future it should more than pay for itself. The manual would have the values of the components and much more valuble information.

Thanks for using FixYa and for the generous rating.

Picture is distorted

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Model hcn4727w screen went black .wont power back

I think you have a ADC that went bad and needs to be checked out. You need to have a service adjustment done by your Service Tech. You just can't fix the ADC without clearing the buffers, and all the other procedures needed to fix this TV. I think your TV repair persons are probably just going over the complex procedures to fix your TV.

Good luck!

Developed herringbone lines

This is a very common issue on these TV's. The pro-scan module is failing and must be replaced. Here is a link to the part number and ability to order it. The module is a plug in device and in the TV is surrounded by a metal shield. The module is very easy to replace and just requires that you unplug the TV before removing the back.

Samsung hcn4727w. All colors out of wack.Curve at

Aging eletrolytic capacitors cannot hold the voltages necessary to keep the color guns in alignment. This is NOT a problem you can fix yourself. The are DANGEROUS high voltages inside your TV which can persist for WEEKS after the set is off.
You must call a qualified service technican for repair.

My samsung hcn4727w will not come on. when pushing

Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978
