It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hello,

This is most probably a faulty DMD chip, because of the snowy effect, if it only happens for some seconds then it might need replacing. Normally this does not go away, have you had any repairs done to this TV recently?

No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

The noise could be one of the cooling fans has some debris in it or the most likely cause is the color wheel is starting to fail and will have to be replaced. If the picture starts to have color or picture problems then it is the color wheel.

Well that humming sound is indeed the color wheel.

Hey thompsonsrj, basing my answer only what little I have learned about one part of your problem you pointed out the screeching sound... my tv also did this and I discovered through research that it is indicative of the Color Wheel going bad. It is a $100 or so dollar part and can be replaced with a bit of elbow grease. As far as the overheating, possible cooling fan issue, I am unsure if they are related? I hope this helps a little? Thanks, Will

See Here:

as well as in your manual. Sometimes the lamp must be reseated
by removing it and reinstalling it with great care making certain
the door and all the gaps are closed tight.

If the lamp replacement or reinstallation does not solve the
problem you will likely need a service tech to look at the tv
as there are few user serviceable items for Plasma sets. Most
of the repairs are done by computer connection that downloads
the error messages and interprets what went wrong.

Hope this helps.

The sound comes from the color wheel and not a fan,common to samsung dlp tv's which can be the cause of the shut down.

Do you mean that red and blue are reversed? If so, you may need to remove a jumper, see end of linked article. Pinkish-yellow or orange sounds like a good description of skin tone, but perhaps too intense. If the color is too intense, can you just lower the color level with the color control? Or can you just change the tint with the tint control? Otherwise, see http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/ including the comments at the end.

We solved the problem by purchasing a surround sound system and hooked it up to the Cable box thus bypassing the TV speakers. It was a cheaper fix than having a TV repair service guy come out and we have even better sound! Thanks anyway!

Hi,If your tv is between 2-4 yrs most likely it's time to replace the lamp.If you hear continuous clicking it could be the ballast which is the board that powers the lamp.If you hear buzzing it could be the color wheel,which is a spinning wheel that creates the color on your tv.God bless you!

you have a bad board, maybe the power supply/deflection board, maybe the signal board, to troubleshoot this problem you need a qualified tv repairman. or you could replace the whole board yourself, the power supply board is about $200, the signal module is about $500, i'd start with the cheaper one, or hope the repairman can fix it at component level.
