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

1 Answer

Tv turned off

Hi, I was watching tv and it suddenly turned off and now it won't turn back on. We replaced the convergence about a year ago. Could it be a fuse or something else? I'm not even sure if there are fuses lol.

Thanks,
Mike

Does the Led blink when you push power? If so let me know the number of blinks. If its dead it may be the fuse but usually theres a cause for blown fuses, usually a short. You can get the service manual emailed to you from the following link, and if you purchase the manual they will provide free step by step support to help you diagnose and repair the set.heres the link in case you want the manual and free support.

Good day!!!I i had problems with the fl 231 fuse on my RCA D52W23 proj.tv....i...


FL231. FUSE.... The RCA ITC222 chasis has a common problem. and it not all that difficult to repair. Does your rca projection tv have read blue and green shadows? Does it have bowing in affect on the top and bottom of picture? when you turn it on does some thin red green and blue line bow in from the top then go away. The main question to determine if you have the fl231 fuse problem is if you go into customer menu then setup do you have the "CONVERGENCE' option. If you do not. then i suspect you have this problem. In the manufactering of these sets Lead free solder is used. now there is great debate over the use of lead free. connection tend to be more brittle. cracks develop around the solder connections of the high voltage flyback transformer. this very small crack set up oscillations in the cuicit with a 400 milliamp fuse. THis fuse cant take it. When this fuse blows the processor then does not know its a projection tv with three projection tubes. it thinks its a crt tube tv. and crt tube tv dont need "convergence" so it removes the convergence from the set.

TO REPAIR... 1. Warning. this set can generate leathal dangerous voltages even unplug do not attempt if you have no experence with electronics.
2. Remove the back. there a number of torx 20 screws.
3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse.
4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes.
5 when you get the tray up the bottom side of the board can be accessed
you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace
6. REPLACE FUSE RCA PART 259213
7 RESOLDER FLYBACK CONNECTIONS simply heat up and add a little solder
8 reassemble set. make sure you examine the set for loose connections.
9 and remember "BE Careful'

Several years ago we purchased a Philips 60" Rear


Hi,
It seems problem with convergence output section of tv and convergence output ICs need to be replaced by professional because it requires soldering work with proper tools.
Please call local tv repair shop to get tv repaired.
Thanks.

Ctc 195 series rear projection T.V. piture quality


It's most likely a failure of the convergence amp and some other power supply problem in the convergence circuit by the sounds of it... Your unit takes an STK730-130 and some 750k 1/4w resistors for the yoke return. I would bet two or more of them are out of value, at least R19702 and R19703... There are also two diodes Cr19710 and Cr19709. P/N# 164590 which commonly open under a load and are recommended to replace anytime the convergence amp is replaced. Also check Q19700 (Bc457) which crosses nicely to an NTE123a...
Not real expensive in a reputable shop - just a pain this time of the year.. I would recommend getting it repaired, it's worth it..

Panasonic rear projection TV 47 in PT 47WX49


Camaroguy: This exact problem happened to us about 8 months ago. A board had to be replaced at a cost of $500. Yesterday, the convergence has gone on the set. You get a blue and yellow shadow on the picture. From what I have been reading, this has happened on a few TVs and it will cost another $500 or so. We refuse to pour more money down the drain so we just went out and bought a new plasma (RCA) for half what it cost us for the Panasonic 4 years ago. We have never had a problem with RCA in the past (two tvs for 20 years a piece).
