Question about Panasonic PT-47WXC43 47" Rear Projection Television

1 Answer

1 ohm resistor, checked ok

I took that resistor and tested it, it seems fine. I have attached a photo where it shows some black spots ( overheating components). Are the service manuals from any good? A lot of those manuals don't include diagrams and complete schematics.Thank you for your help.

TV won't switched ON. Front LED blinks 5 times ... pause ... 5 times again, and so on. Stand-By 7V checks OK but relay RL801 doesn't click.

Ive replace the convergence IC and the whole power board and tv set still wont turn on. have a voltage regulator on the way now to see if that is the part thats messed up. cant figure this out. resistors...

Resistors need to have one end of them unsoldered and lifted out of circuit to test with the ohms meter leaving them in will often give a false reading since they tend to measure circuit resistance when checked in circuit.

How do i no if my resistors on my convergence bored are bad. is there a way of testing each individual one and i hear something abought fuses. could this be my convergence problem i am having

What seems to be wrong with your TV? You need a Volt ohm Meter to read resistors/Componets
Mats Electronics has them for $29.00 and up 1-800-628-1118
Convergence ICs are big black ICs and will have PN on them ,example STK392-110
resistors in convergence should be 1ohm 1 watt.

Zenith R60v26 has burnt resistor at RK5 on convergence board

Hello, I have the exact same issue with my R49W36, I replaced the convergence chips but there are also two 1 ohm resistors with the same color pattern as yours that are bad. I have looked all over and cannot find a 1 ohm resistor anywhere. Where did you find it?

TV Has 3D Look Hitting used to fix but not anymore

The convergence IC's are bad. (They are probably STK392-110) If you look at the connections, yuo'll probably see little rings in the solder where the pins come thru the board. Your problem probably started as bad connections and has now led to complete failure of the IC's. Replace them both. Look for burned resistors

TN50X81 - one convergence IC runs hot...TV powers off after 5min

What was the STKs that was in set ? If 110s always upgrade to STK392-180s. If they were 392-560s go back with the same. they worked differently then the 110s 150s 180s

Conversion Problem

did you remove one side of the resistors before checking them with the ohms meter? They have to be out of circuit to accurately check them. Also you need to be careful where you purchase the ICs as alot of places sell the chap chinese versions and they often fail within a few days. Heres a link where you can get quality ICs and resistors as well as free tech support.

1 ohm resistor, checked ok


these hot spots are in power supply you can run some solder on it but it should not be causing this problem can you please take a picture of your TV while it is on and show me the picture of it plus tell me exactly what it does.
