Question about Samsung Televison & Video

Open Question

Samsung Plasma TV takes anywhere from 5 minutes to 4 hours to turn on & work as it is suppose to. I have replaced the main board & y-main board & the same issue remains. Replace the main logic board?

Model # is PN50A510P3FXZA. The detailed issue of the TV is as follows: when I turn on the TV, the TV makes a clicking noise and then shuts off. The TV does this a couple of times. Then the TV will turn on and make a loud popping noise and the picture is not clear with lines going through it. The TV will then shut itself off and turn back on with a loud noise and a distorted picture that alternates from getting better to worse on each subsequent cycle. This process will repeat until the TV finally works as intended. If I replace the main logic control board will that work or is there another board I need to replace?

SOURCE: No picture or sound after replacing lamp

Possible bad color wheel...

Pull the lamp out & look inside where the lamp sends the light-

does the color wheel look defective? If so,replace it.

Or, the lamp ballast may be bad.After that,usually replace

complete engine.

I Can Assure You That This Problem Is Associated With 2 Capicators On The Power Supply Board.

SOURCE: Red noise or flicker on bottom half a plasma screen

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

SOURCE: TV shuts itself off after a couple minutes of being on.

One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem.

In most of the case, the problem is the main board, you may try the below procedure to fix the problem:

Re-Flow Soldering Procedure for Main Board

    1.Pre-heat your kitchen oven to 385 degree (No more than 400 degree);

    2.Put the main board on a card board (like a pizza box board) in the oven;

    3.Heat it for 10 minutes (No more than 10 minutes);

    4.Turn the oven off & leave the door open, at this moment, do not touch or move the board until it colds down to the room temperature.

    5.Install the board in the TV & try it out.

Samsung pn59d6500df display turns off after 5 minutes. Comes back on when unplugged for a while. Cannot see any bad caps.


Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its 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. Surf the site with patience. Pull up older posts.

If Vs & Va voltages will differ to an extent, this type of fault can occur to Plasma TVs. The adjustment to these voltages are possible, and the adjustments presets are there at the power regulator board. Please contact any service technician before replace the power board. Even though you replace this board, you have to adjust the above said voltages after fitting the new power board too.

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.

Light blinks but tv won't turn on


If the TV is less than one year old is covered with factory warranty by Samsung. Give them a call ringing the number listed on the owner manual.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Red blinking light on a Magnavox Plasma TV


Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture. There is no sound, TV comes on and then after a few seconds clicks and screen remains blank.

Cause:

On the main power circuit board to Capacitors are prone to failure from over load. The caps are 3300uf 10v 105+c capacitors located to the left of the AC power input.

Service:

Magnavox will refer you to a service center. They will advise $$$ for an inspection. They will also want to charge upwards of 500$ to replace the entire board.

Solution:

1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.

NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)

This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.

Hope this all help, Magnavox is should take ownership for this problem and recall any tv's that have these caps in them. The worst part about this is that teh **** from the repair center that was paid 100$ to check the TV, stripped out the screw holes and damaged the case for the TV.

Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

Samsung plasma sp-r4232


Remove the power supply cable to Y Main board, check Vs on power supply board when you turn on tv.
1. If you have normal Vs, replace the Y Main board. If still not work, replace the Logic board.
2. If you don't have normal Vs when you try to turn on your tv, just replace the Power Supply board.
