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

3 Answers

Shuts Down Immediately When Turned On

Can you help ? Seems like a lot of people have this problem. The set worked fine for years and all of a sudden started this. There are no blinking lights and I did unplug the set - once for 2 days with no results, and once for 6 weeks while I was out of town, also with no results. The set is actually listed as model PT47WX49SE if that makes any difference. I really like the set and would hate to have to give it up. There are no repairmen listed for my area and I would have to find a way to transport it over 250 miles to the nearest other town (in Alaska). I am relatively fearless when it comes to sticking my hands into something to repair it, as long as I have instructions. The last 2 computers I have had I built from the board up, so I am not totally ignorant of electronics but have never "messed with" any television sets, so I do need advice. I could do whatever is required as long as I had the repair manual with schematics but I don't even know where to start troubleshooting. Thank you for your time, I appreciate your input.

    In response to Tim Nolan - it is a resistor glowing - I have a picture of the board but don't know how to post it here - I can tell you which one it is if I can post the picture.
    Thanks - Sherrie

    From reading a lot of the other posts, I am guessing that it is indeed a convergence problem. Do I need to replace the ICs? If so, what are the pros/cons of replacing the 110s with 115 or better ? I do have the service manual and while my soldering experience is more along the plumbing line, I do have a friend who is into electronics & might be persuaded to help me out here. Thanks

    You Guys Rock !! Thank you so much - I am now ready to tackle this job and am confident that I can be successful at it. The link to cmpalmer's blog was extremely helpful. Thanks for saving me a ton of money and for opening up a whole new area of DIY for me - hey, if a 65 year old grandma can fix her HDTV - Life is Good! I am a firm believer in the old adage "if you can read and follow directions, you can do anything". Thanks again for making that statement a reality. Sherrie

    I have a 4 year old Panasonic PT47-WS49SE. When I turn on the tv, the
    red LED comes on, then turns off about 2 seconds later. It won't turn
    on again after that unless I unplug the tv and replug it back in. Then
    the same thing happens again.


    Model Number is actually a PT47-WS49SE. Issue is the same unit turns on
    for a few seconds but I have to unplug it and replug it for it to do
    the same thing every time. So input would be greatly appreciated.

Hi,

Your post "no blinking lights" is significant. It initially tells us that the problem is in the frontend of the power supply which could simply be a fuse, powercord, cold/loose solder and/or any relatively easy to spot and correct problems. So offhand, exploratory diagnosis and checks might be in order. Since you are considering a DIY (do-it-yourself), pls post back if you have access to a DVM and a soldering iron. Additionally, pls see this post here at FixYa and look into the possibility of getting a service manual.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

First take the back off, then when you hit the power button can you hear a click from the relay trying to turn the set on? Or does it do absolutly nothing? If you can hear it click and try to come on then stand behind it with the back off and look in while you have someoen try to turn it on. Do you see any resistors glowing? If you see resistors glowing and they are near the two large STK392-110's then you have a convergence problem. If you dont hear a click at all then you may have the relay resistor open. If you can take a digitol picture and post it here then take a picture of the back of the set with the back off and I will circle some things for you to check and post it back. Let me know what you find out.

    Sherriem,



    Dont make this more complicated than it is, you dont need to go buying manuals or looking at websites on how to fix it, your just going to get confused. If the resistor that is glowing is right in front of the STK's then all you need to do is replace the STK's. This is an EASY fix if you or someone you know, knows how to solder. As for the 110 vs 115 questions, it really doesnt matter. My company uses 110's all the time and we never have them go back out on us. So let me know if you need more help or instructions!



    Thanks

Dell Inspiron 530 randomly shuts down and restarts


Sounds like it could be a virus. Or, a heat buildup problem - are all fans inside machine working? Is the fan inside the power supply operating? Was there any work done inside the computer recently?
If the hdw is all ok, go out and buy yourself a copy of Norton Internet Security 2009 - 1 user lic - $49.99 @ Staples. Do *not* buy any earlier vers. of this software! Install, update it, run computer computer scan - probably will find/remove some/many viruses.

If this helps, please take the time to rate my response to you.
Thanks and good luck.

Samsung DLP TV HL-R5667W shuts off intermittently


Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set
