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

1 Answer

Identifying resistor After opening up the back, I discovered what appears to be a severly dis-colored resistor. Any help in identifying it aside from buying the service manual-schematic ? Thanks much !

Re: Identifying resistor

Look at the location marking on the pc boaed and record the number of the resistor  and then we can find the value of it via schematic /parts list ,also require model #

Error Code 2-2. (Low Voltage Supply) What now?

That is a power supply issue and this requires a skilled person to do it.Trouble shooting in this kind of problem includes voltage measurement and resistance reading of the components/parts inside the high voltage section This is not a DIY problem but if you still want to do it yourself then I can give you some guide that you can try.
1.Check the power supply board,this board is where the power cord is connected.The common problem on this circuit are the filter capacitors .A leak and shorted capacitors always cause that kind of problem the worse is dead set.To visually identify a defective capacitor is their appearance they look to be bulging on top blown,theirs a liquid leak on the body.replace the defective capacitor if you found any.with the same rating and value..
2.Resistors -change value resistors and open resistance can cause the same problem this resistors usually near the regulator transistor.They appears as burned and overheated replace it with the same rating there is an available color code calculator of resistor in the internet click this link and key in the color of the resistor to get the value..

3. check the voltage regulator transistor if it is shorted .the first pin and second pin must not have a reverse reading..

4.Check also the two big IC marked with STK xxxx this IC are the convergence IC it controls the horizontal pin of picture..when this IC are defective this will shut down the power supply ..

The steps I mentioned must be done with a skilled personnel If you feel you can do it,well you can try or better yet bring it to the service center or call a service this link for service center
good luck hope this helps!

The screen piture will not appear, the lamp light flashes red before all lights flashing, how do i solve, thanks

In this case is best if you replace it, but first, try identifying any awkward noises, if it's clikcing the issue is with the ballast, if it's humming, it's with the color wheel, and if you replaced the lamp already, it's most probable that the issue would be either ballast or colorwheel

52 in philips help.

the large IC's on a big heat sink is where the convergence ic's will be
here is an example
the resistors will be on the lines of these IC's
need help identifying the resistor values?

Replaced ic on philips you told me about which resitors are 6.8 ohm ....

your model is 55PP9352/17 correct? If so all the resistors from R3149 - R3160 are all 6.8Ohm 1watt 5% tolerance. metal film resistors. The resistors in your upper pic 3157 and 3158 appear to be open by looking at the pic I cant actually make out the banding colors to determine what rating they are. But if your set is a 55PP9352/17 they should be 6.8 ohm. let me know the actual color of the bands in order and I will post the ratings of 3157 &3158

Color convergence red and blue will not line up/ double images

Repair involves some dis-assembly...replace convergence IC's
and inspect current limiting resistors for over-heat damage...
part # STK392-110 sub to upgrade STK394-160 Hitachi part # CZ will need two....good solder technique required.

PT-53WX42 IC replacement

The two convergence IC's are generic part# STK392-110 and Panasonic part# C5AA00000203. Also check for burnt or discolored resistors nearby. Since this is such an easy repair,a schematic is not necessary....The hardest part is identifying the burnt resistors and aligning the green convergence in the service menu.

Hourglass Picture

it easy to locate the fusible resistor in the power module PCB,it look like a resistor but white in color,normally printed soc xxxx (2100) on top of the component. After you replaced the STK392-110 , you need to re-alight the convergence setting again.hope it will help.

Colors became distorted, then it shut off

Your tv has two problems showing up at the same time,the convergence IC's have loose conections in some of the conecting pins,the Ic's are mounted on heat sinks and can be identify by the markings on its face STK--- ---,3 letters and 6 numbers,one IC for each color,this pins need to be resoldered as well as any other loose conection or overheated areas in the board. The shutdown problem might be a resistor next to the output transformer,its value should be .47 ohms but it might measure open right now,the resistor is at the back edge of the circuit board on the right witch is the deflection board.If you are familiar with tv service you have a place to start but if you are not too familiar be safe and call for assistance from a servicer.Let Us know how it goes.
