Samsung HDTV HPS5053 - Can main board Rev be swapped?

I have the sparkle problem several others have reported which seems to be universally attributed to a bad main board. I know there were three revisions to this board and I know mine has BN94-00925A.

My question is will the B or C board also work or do I have to find an A board? I've been looking and A boards are scarce and far more expensive.

Samsung LN46C610N1FXZA SOUND fine no backlight. flashlight test shows video is fine. voltage test on power board is double on all voltage points,

Sorry to hear that, it seems video processor chip failure on main board and entire main board swapping is needed, please note that there are various different version of main board utilized in this one mode so it is very important to get identical main board as replacement that has same part number.

Screen keeps losing colour and ends up with a blue tint

On this model there tend to be two problems. One is that the power supply capacitors fail early and often. While this typically caused no power or slow power-on, it can cause other issues as well.

Loss of color typically means the 'Main Scaler board', which is the main board where all the inputs are attached, is having an issue.

There are some problems reported with a faulty crystal on the board causing loss of color, although most techs would just swap the board as these TVs are meant to be serviced at the board level, not the component level.

I assume that this loss of color happens on any input source, including when using the internal setup menu of the TV? This would help to confirm that the loss of color is not related to a faulty input signal caused by a bad cable.

Makes you wonder why nobody is taking on the problem, doesn't it?
Well , to the best of my knowledge, it is because nobody really can.
To understand why you have to understand what do they sparkles come from.
They are random electricity discharges coming from capacitors or other components that act like capacitors, but mostly capacitors.
When laymen hear about capacitors they usually associate the word with bulged electrolytic capacitors, which often cause problems in electronics of all kind.
Well this time it isn't about them.
It's about all other capacitors - or other components exposing similar qualities - which are installed on the board. Most of them are small filter capacitors put in parallel to the big ones or to other passive components such as diodes and resistors.
The excessive heat developed by the sustain boards damages those capacitors. It hardens the electrostatic material they are made of and small breaks in it start occurring at voltages that shouldn't otherwise be causing issues.
The trouble is, they can be everywhere. You can't just pinpoint which ones were caught at fault and causing the sparkles.
When it gets REALLY bad eventually the whole capacitor burns and either shorts or, more commonly, just breaks.
Believe it or not I've seen a board that exploded before my very eyes and , after the explosion, started working LIKE A CHARM!
Turned out a small filter capacitor had blown. It as not essential for the board's functionality and after being problematic for so long and causing image deffects it had eventually shorted completely and literally exploded.
Luckily, the short it had created was too short in time and apparently in a circuit that could take the load for a short while without getting damaged.
So after it blew everything worked just great!
it's a real story from my repair experience.
Hope this helps all consumers, DIY enthusiasts and competitors alike :-)

Many TV's with an LG plasma display (or built by LG for other manufacturers) have a manufacturing defect that has been reported widely on the Internet. LG, Akai, Samsung1.gif and Zeneth among others.

The sparkles are (usually red) visible on a black background with all inputs after the set has been used approximately one year. Soon after a pop is heard and the picture no longer shows at all.

LG and some other manufacturers using the LG displays have not acknowledged this defect and will only repair them free during the warranty.

Often techs will merely adjust voltages and or picture controls, which does not fix the problem but it just disguises it -- until the display blows -- usually after the warranty expiration.

I own a 42" Akai that is 9 months old that has recently been showing the red sparkles. My set is being replaced.

You should contact service if your set has this problem is under warranty and it should be replaced at no charge.

Good luck. :)
