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

1 Answer

Widescreen thinks it's a big screen

I moved my Panasonic PT47WX49 and when I plugged it back in, it now believes it's a big screen, rather than a widescreen TV. The picture comes up as if it is zoomed (even the user menu); there's no way to change the aspect and I now have PiP instead of PoutP. It's this way on every video mode. It is as if the computer inside has an identity crisis. Before moving the TV, my roommate was in the maintenance mode adjusting convergence and color. Has anyone seen this before? Does anyone know what can be done to fix it? Thanks for any help. David

Re: Widescreen thinks it's a big screen

Information as to the type of signal input is needed to resolve this problem. Does it appear in zoom mode when playing a dvd, or just in catv mode? Some times an HD cable box must be reset to a particular aspect ratio. This can be done by reading the owners manual of the cable box manufacturer. Scrivitron

Pt47wx49 panasonic rear projection tv has very dark tv scenes

Has this problem been getting progressively worse? I would suggest cleaning the CRT's inside the tv with lcd screen cleaner or something similar. Make sure the tv is unplugged, all you have to do is undo some screws on the back to gain access to the inside of the cabinet. Hopefully that's all it is. Your set has no lamp if it is a Panasonic Pt47wx49.

What is the standard price of the convergence amplifiers and how many are needed for a 48 inch HDTV?

If it is Panasonic PT47wx49 it uses two STK-392-110 CONVERGENCE chips--On Ebay select search, then advanced search and then search by seller---look for seller: sewsales55 You can buy both chips for about 12 dollars plus shipping(price for a pair with 6 month warranty)

If you need instructions on this repair let me know--pretty easy set to do this on--

Panasonic pt47wx49 taking out board A to replace IC on heat sink

You have a problem with the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board (not sure what you mean by white clips, but you should be able to take out just the convergence board) and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conducting piece of plastic to push the heat sink when doing tests.
If soldering doesn't help, then the modules have died and need replacing. Don't buy the $10 cheap ones. Most of them have an upgraded version that is stronger. Also look for any burned resistors in the vicinity of the modules.
Best of luck, hope ya fix it.
