Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Detailed problem per your response

Normal 0 I had a convergence problem with my pt-47wx49e, as manyhave, and replaced the IC units and unit still did not work. I just replacedthe 2.2 ohm resistor in the R7035 slot and turned on the tv.The resistor started glowing red and then the tv shut off. Should I replace all2.2, 82, and 120 ohm resistors around the IC units? Or is there another issuethat I need to address? Footballseason is in and I need to fix this tv. Thanks for your assistance. (Post 1) – responsewas take it to a repairman, it was board issue.
I need to explain the problem. The screen went to anhourglass-type view while my wife was watching the tv.It remained this way for a couple of days then my wife smelled somethinghot/burnt and the tv went out. I ordered new IC units and replaced them, onceagain the smell returned. I then purchased some Panasonicresistors and changed one of the 2.2 ohm resistors and plugged the tv in. Thetv came on for a few seconds, not connected to an antenna, and I noticed thevery 2.2 ohm resistor turn red and the smell returned. I have purchased anotherset of IC units; this time they are the 110's instead of the 180's that Iupgraded to. My question is if I replace all of the resistors around the ICunits (i.e. 2.2, 82, and 120 ohm resistors) what is the probability that thiswill rectify the problem. I have no manual as one response inquired about. – responsewas check the manual (which I do not have)
The nearest repairman is 45 miles away, and no meanslarge enough to transport this tv. Canyou suggest anything I can look/test for in order to diagnose this problem? Ihave the other resistors from Panasonicand new IC modules (OEM). Can you advise where to look?

The problem is that the ICs may have been blown because the resistors were bad. Just as a double check before you replace anything else. Please confirm that the STKs are STK392-110. Also, replaceing them with STK392-150 is a valid upgrade, I'm not sure about the 180s, but I'll check. Both the STKs and the resistors need to be changed at the same time.

The hour glass view you reported: Was the bowing on the top and bottom or on the sides?

Thanks,
Dan

I would look for burnt resistors off the red IC, hopefully its not the DCU (digital convergence module) as most of these are integrated into the signal board. here is a tutorial i made up:

converge outputs getting tired or limiting resistors opening up. adjusting this incorrectly will make the situation worse keep in mind that overdriving these chips will cause a fold over of your image when you see this carefully adjust in the opisite direction as you may be overheating the outputs

Just click below for convergence repair kit;

Blue wave coming up frpm 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;

your convergence IVs need to be replaced. Its an easy repair if you can solder. you can get the two ICs you need at the following link. they also provide free installation instructions and free on line tech support while youre doing the repair. You need two ICs they are numbers STK392-110. Let me know if I can be of further assistance. I am one of servicemanuals support techs and board rebuilder.
