Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

1 Answer

Failed resistor Tv would not turn on. Got three blinking lights. removed the back and found a resistor that was discoloured. Is this the problem?

    Thanks Slinteriors.

    One more question, If I leave the tv unplugged for 48 hours would that be enough time so I can work on the board without being shocked.

  • coolmike711 Sep 06, 2008

    I want to remove the board. How do I discharge the power so I don't get shocked.

  • coolmike711 Sep 07, 2008

    Slinteriors,

    I replaced the resistor first and it burned again. The I replaced the IC's and the resistor and the same resistor burned again.



    What now...

  • coolmike711 Sep 07, 2008

    The other five read the same, I figure they are good. The burnt one has no reading.

  • coolmike711 Sep 07, 2008

    Yeah, I am about to do that. We will see what happens.

    What is the convergence yoke and where is it?

Those are the convergence feed resistors. # blinks on a panasonic means convergence IC failure. You will need to replace the two stk392-110 convergence ICs and the six resistors. You can get replacement ICs and resistors at the following link.

    first off leave it unplugged for at least a half hour, then when you remove the HV lead just ground the end for a few seconds to be safe but most dangerous voltages will drain done after a half hr except the CRTs but your not going to be unhooking them

    there are six of those resistors which are all the same rating unsolder one side of the resistors and lift it out of circuit and check the resistance of all six resistors

    If you have replaced the ICs and resistor and that one resistor keeps burning you will need to trace that circuit with the schematics to see what other components are on that one line with the resistor and one of those components have to be shorted or open. Possibly a capacitor or diode itcould also be the convergence yoke for that line.

    the convergence yoke are the small rings on the neck of the picture tubes closet to the circuit board on the end.

Panasonic PT-53wx54j" Rear Projection Television blinking light 3 times, wont turn back on. Originally turned off by itself


sounds like a bad power supply my mother has one done the same thing we found out he power supply went bad $125 to fix so we junked it and she bought another TV

Restore factory inputs


Especially if you have the three blinks error code:

No reset code, the three blinks shows the power supply failed to start correctly

3 blinks means a power supply issue which is not related to a reset which this set does not have.

TV wont turn on but it does make the clicking noise as it is trying to do so, the power light flashes three times and extinguishes


The three blinks is an error code indicating that the convergence has failed. You can get the PT47WX49 convergence repair kit from www.tvrepairworld.com whih has the 2 Convergence ICs and The 6 low ohm resistors plus the CD with repair instructions.

Panasonic pt-61hx42, turned on tv and the power light blinks three times in a continus pattern. I assume this is a power supply problem, can you tell me which componet is blown?


The three blink error code is the error for failed convergence ICs and the low ohm resiustors. You can get the convergence repair kit for your model from www.tvrepairworld.com which has the 2 ICs and the 6 low ohm resistors plus the kit contains the CD with detailed repair instructions.

I have a panasonic pt-47wx42 projection monitor. It will not turn on and the red light next to the power button blinks three times


The 3 blink error is caused by failed convergence ICs and the six 2.2 ohm resistors. Installing the convergence repair kit for your model should solve the issue. The kit is available from www.tvrepairworld.com the kit contains the 2 ICs with heat sink paste, the 6 resistors and the cd with instructions

What does three blinking red lights mean on the power, when my tv just turned off on its own no warning?


The three blinks is indicating that the convergence circuits have shorted and have shut the set down. You will need to replace the two Ics and the 6 resistors. You can get the repair kit for your model which contains the two Ics the resistors and the CD with repair instructions from www.tvrepairworld.com

Tv still turning off blinking three times after hori ic replaced


Three blinks is short protection.

97% of the time it means one or more of the 2.2 ohm blue resistors around the two convergence IC's is OPEN.

There should be 8 or 10 of them: light blue in color and will have 2.2 printed on them ------look for any that are slightly discolored or white in the middle.

What happens here is if one opens====one of the two convergence chips got it----they can be tested in place like testing a fuse===no reading across any of them and it is gone-----set detects no voltage reaching the chips(Usually STK-392-110---black in color and on metal heat sinks with fins side by side.)

DO NOT JUST REPLACE THE RESISTOR IF YOU FIND ONE BAD=ONE OF THE CHIPS GOT IT.

I have start to finish, step by step instructions showing what is needed and the best way to replace the chips etc.

FIRST: LOOK TO SEE IF any OF THE RESISTORS ARE GONE. (BAD)

If you want the instructions let me know and I will post them here for you.

Regards, SD TECH


FYI= Whoever told you to replace the output transistor does clearly not know these sets very well as it will produce a 5 blink error code.

My rear projection tv just failed me by turning off. The picture seemed fine, no convergence, but it turned off while the power indicator blinks three times. Have read similar posts, but did not have the...


Yes, the three blinks is short protection. If one or more of the 2.2 ohm blue resistors is white in the middle one of the STK-392-110 chips got it.

I may be the one whose post you saw. I have start to finish step by step instructions for this repair in this set.

I can also tell you the best place to get them and the instructions tell you everything you will need and how to do the repair in the best way.

They are based on the fact that I have fixed hundreds of these sets with the same problem you have.

TV turned off and now the power light blinks three times


Very common problem. 3 blinks means the convergence circuit has failed . Heres a link to the repair kit for your model which contains both convergence IC and the feed resistors and the kit has step by step instructions with pictures so you can easially do the repair yourself.

CONVERCENCE PROBLEMS


did you replace the convergence resistors with the ICs? Often the resistors will need to be replaced also when new ICs are installed. 3 blinks means convergence Failure so its either the solder connections on the ICs or the resistors need replacement. If you need more assistance please let me know.
