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.

My TV is a LG 47LN5700-UH I had a lightning strike near the house. Afterward TV would start but not boot completely. Now it won't start at all. Cable box also got fried at the same time.


The led driver AND the T-con board are bad. If you could see a picture with the flashlight then the T-con board would be good. It is not. The led driver can be on the main board or the power supply board. You can get these parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Why should I treat every race equally when not every race behaves equally?


For the sake of argument let us suppose that all persons having some physical characteristic a "race" and all those who are not in that particular "race" do not have that characteristic. To therefore conclude that the race behaves badly you would have to show there was a cause-effect link between the physical characteristic and the actions of every individual having the defining characteristic of that race. For example, if it were that blue-eyed people universally hated cheese and the rest of the world universally loved cheese you could say that there was a good chance that their was a causal link between blue eyes and hating cheese.

But when it comes to the real world scientist have never found a single action or attitude displayed universally by one "race" and not displayed by a single individual outside that "race." No casual link has ever been made between physical attributes and actions and attitudes. What causes people to act badly or well is not there race but their culture. And culture is not the result of race but of conditions, heritage and history. What is at work when you (seem to) claim that some races do not behave as well as others, is that you confuse culture with race. I suspect you do so because in your experience certain actions and attitudes have been consistently displayed by people with similar characteristics. You therefore sense that the race is the cause of the action and attitude. And while there may be a correlation between a certain physical characteristics and certain attitudes and actions, correlation is not causation. It is unlikely that we will ever find that a set of physical attributes unfailingly lead to a particular set of attitudes and/or actions. In other words, "race" is not the cause of the actions and attitudes you might label as "bad," but culture may be.

That there are cultures which are worse than others is hardly disputed, assuming you have any sort of preferences. But one "race" being better than another isn't tenable with our current understanding of how physical attributes influence attitudes and actions. It's culture my friend, not race.

Try replacing that evap thermistor. The diagnostics on thermistors can be wrong. If it is rounded on the end, replace it. There is a damper between the freezer and refrigerator. There may be a refrigerator fan motor in the damper assembly, It could be bad. It could be a bad control board. When you run diagnostics there is one function that checks all the fans.

WMG30GS Whirlpool microwave display


please follow this steps and fix it. God bless you
  1. Main control board If the display on your microwave has gone out completely this is usually a sign that it is a malfunctioned main control board. To correct the issue the main control board would need to be replaced.
  2. Display board A display board can either malfunction completely or partially, causing two separate results. If the display on the unit has completely gone out, this can be attributed to either a bad main control board or display board. On the other hand, if the display has only partially gone out, this is usually a sign that the display board is defective and will need to be replaced

When turned on, monitor power light comes on for a moment and then goes out. Monitor eventually comes on after several minutes. The same happens if the monitor is left on but goes into sleep mode.


This is a common problem on these monitors. There are three or four capacitors in the power supply, three on the inverter board and anywhere from 2 to 6 on the main board that go bad.

The number on the main board depends on how long the monitor has been having problems before it was serviced. The longer the wait, the more capacitors will have gone bad.

The power and inverter boards are easy to repair, the main board is not. As mentioned, it is a multi layer board so removing the old capacitors and the old solder can be troublesome. I would suggest you have someone experienced at soldering repair the main board.

Btw, our shop would charge $60 labour plus $2 for each capacitor.

LG 42PX5D sparkles on black


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
http://electronicshelponline.blogspot.com/
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.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sparkles


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 :-)

Tv seems to need to warm up


This is a pretty commom problem with this model. As it has several bad capacitors that go bad. If you have no solid state repair experience, and to save you from any high voltage shocks that can kill you, i would highly advise you to contact a local authorized repair shop to assist you in the repair of this set. As much as you really want to repair this set yourself, To do so would be tempting faith! As a Tv set these days are all solid state and have no user serviceable parts inside of them and to try and experiment with them, could be very harmfull and a risky thing for the user to do. Please find a trained tech to assist myou in the repair of your set. Good luck , and please report back on how the set was repaired.
