Convergance - Protection Mode TX51P250

Hiya Its a TX51P250 RP-TV that has the standard 3-blinks of power light, inspection of the D board revealed that 4 10R Resistors burnt out inline with the STK 392-110 modules, after replacing modules twice with new units ex USA, and have also replaced the resistors/rebuilt tracks, (new resistors are 0.6W not 0.25W) still get the 3 blinks on power on and protection mode clicking out.

Any suggestions for next steps? Nothing obvious has presented itself ie no further scorching,

Any assisistance is gratefully acknowledged in advance...

Regards

AJ

http://servicemanuals.vstore.ca/

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Light blinks three times but dont turns on


  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

It may be made up of a few faults but the power supply is a good place to start.
Hope this helps

The standby light on my sony television keeps flashing on and off. It will not turn on.


The TV is on protect mode.

Try first leaving the TV power cord unplugged for at least a couple of hours.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.


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.

Blank screen. When I turn it on the Stand by/Timer light blinks twice and the Stereo light blinks once.


THREE Blinks = over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.You need to replace these components. Just as a tip it would be better to have this done professionally rather than DIY Please rate our help to keep the service online

Green light flashing


About the second user with the remote problem, the problem is likely a bad IR sensor/board inside the TV, The IR circuit is the one that receives the remote signal.

About the original problem with the light blinking instead:

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.

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.

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.

Toshiba cz32v51power light flashes, with no picture


That means that an internal error had been detected, and now the TV is on protection mode.

To start unplug the power cord for ten minutes, and see if the TV restart.

If it does not try leaving the set unplugged for longer, let say two hours.

If still no luck call the number listed on the user manual, as the TV has an internal fault, and must be repaired by a technician.

My 37" LCD maganavox tv won't turn on - it blinks green and then eventually will turn solid green and then the tv will come on. This has been happening for a few weeks.
