Question about Panasonic PT-47WX53 47" Rear Projection HDTV

1 Answer

R517 Burnt D" board

After checking the schematic on the D" board' Replaced R517 with the proper 10 k reistor checked d509 found it open no back to back reistance replaced it with a 1 KV. fast switching diode , found C524 measured .24 uf with my capacitor meter and replaced it with the required value of .22 uf 100 volts.
Powered up the tv and it shut down' with the resistor heating up, I removed the output lead from the flyback to the flyback divider .
The unit stayed on and I was able to measured 20kv with my high voltage meter, at the output from the flyback, and it was naturally to low.
My question is do I require the flyback as well as the flyback divider or just the flyback ?

You will need the flyback as thats way to low. The HV splitter will only direct the HV to each of the CRTs it doesnt change or regulate the HV in any way just directs (splits) it. Let me know if you need any more assistance.

zenith are famous for bad soldering even going back to the 80s with the 960-05 boards in the space command sets.
i would pull out the circuit board and check the soldering before doing anything else.

Check the voltage across R517, should read about 12v if not replace C524 which is your AC gournd return and possibly D509 feed diode. I suspect that you get enough voltage to trigger the relay but just before B+ happens the 12v line drops well below the trigger voltage and the relay re-opens.

Low ohm resistors are open or poor solder connections on the bottom of a convergence IC.

You need to look at resistors in good light with magnifying glass. Bad ones may show as discolored or burnt.

The repair needs someone that has the schematic for the convergence cct, and can replace the burnt resistors or replace the whole convergence board.

If you are near Calgary, call me, if not, find someone that has done it before, preferably many times.

if you know aything about tvs which it appears you do check to see if you are getting voltage to the horizontal output ckt at the collector of the horizontal output transistor if you are probably you either have a horizontal drive or output problem if you are not check to see if you have either fuses or icps or pico fuses are open generally you will see about a 135 volts to yhe hoizontal output ckt.

Plug in tv and doesnt work


If you have no Tv repair experience, how do you know what part this is?, as I dont have a clue as you didnt supply a schematic or a picture of what the part was. We techs have a trade we learned not by doing but by going to school to learn the theroy behind the circuits. If you know how to read a schematic diagram, i suggest that you get one and know what part it is that you think you found burnt out. If you go to http://www.servicemanuals.net, download a service manual or schematic diagram, i will assist you in this repair as long as you have the proper equipment such as a mutimeter and know how to trouble shoot solid state electronics. Its not a tube you can take out and test or a board that can be exchanged anymore my freind. Its down to the componet level these days.
