Does the Blinking Light on the Asic Main logic board mean bad Logic Board?

YES--Probable Blown Cap.

Main digital processor IC on the board has damaged. It is not a replaceable part, as normal soldering techniques cannot be applied to de-solder it out from the board, or to solder a new one in place. Card base replacement should be done.

U have all the tools?U know and understanding basic electronic and also can do basic soldering work too?Yes?All tvs with LED power light indication blinking lights are 70-80% are problems relating to the tv power supply board.That the board where the tv power a/c cord plug into it.Tv must have be unplug and taken aparts and by checking the tv power supply board carefully by looking for leaking and dying components parts that are called capacitors parts.These dying and leaking capacitors parts are very easy to spots.These capacitors parts are alway bulges up on to it tops and will not have a normal plat tops like is suppose too.U should replaced all these dying capacitors parts with the same Micro Farad and it voltages up like 5 or 10 voltages higher than those old voltages that are was lables by those old capacitors parts was in the board,this tv will solved this tv problems.But these Plasma tvs are having a very common problems with it Y-Sustain main logic tuner board too that the board where it take in the tv incomming broadcasting signal wire plug into it must have to be replaced too,if the tv power supply board have no problems or was fixed but did not fixed the power light indication won't stop blinking.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board and or the Y-Sustain main logic tuner signal board for the replacement.

The tv main logic board known as a tv Tuner signal board it is the causes and the problems.The tv main logic board,the tv Tuner signal board it is shorted and not taking in and sustance power from the tv power supply board anymore that why tv Power and OPC LED lights indication are flashing together.This main logic tv Tuner signal board that the board where that take in the tv incomming broadcasting signal wire plug into it.U must replaced the main logic tv Tuner signal bard to fixed this problems.If U have some mechanicals skills like take things aparts and putting it back together again?Yes,tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish main logic tv Tuner signal board for the replacement.Tries tv unplug,replug it back about an hour later.Tv might work again for awhile though,but to fixed this problems for good the main logic tv Tuner signal board must have to be replace.

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

Disconnect the LVDS Cable that runs from the small signal board to the display panel and apply power,if the screen comes on,the Small signal board (aka Scaler Bd ) is the faulty board. other than that,all that's really left that has gone bad for me is the logic board.

usually blink code on front gives direction but first thing to do would be to determine if surrounding sustain boards are causing draw on power supply by disconnecting them one at a time from power supply. y is on left looking from back and x is on right looking from back. if led goes solid with either board disconnected check supply voltages and if come up and stay up replace that board. if no change then you would need to verify vs on command coming from logic main to power supply. should be labeled on power supply connector and should be 3 volts. if present replace power supply if not present verify if logic main board sitting underneath signal board has one solid and one blinking led on if verifying normal operation and if so replace small signal board

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/

This what to do measure from the logic board which is located under the small signal board and have the AV jacks connected to it. If the voltage is 3.1 or close the problem is with the power supply or a boar connected to the power supply. Unplug the set. Disconnect the Y main board first that will be on the left side of the set facing the back. Plug the set back in if the led is solid replace the Y main and the Y upper lower. If still blinking plug the Y main back in and unplug the X main which is on the right side facing the back. If the led is green replace the X main. If the led is still blinking replace the power supply.
But if the volts are 0 the problem is the SSB or the logic board. In that case take the (SSB) small signal board out the set and place 1 jumper on J8003 and another jumper J8004 of the left side of the power supply. Then place 1 jumper on CN2072 of the lower left part of the logic board. Plug the set back in if the set displays a white, blue ect screen replace the SSB. If not and on the logic board you don't have 1 solid blue led and 1 blinking led data is not flowing and change the logic board.
