Question about Televison & Video

1 Answer

I have a Matsui TV model M32LW509. When its switched on it only stays on for a few minutes and then powers down.

I have tried unplugging it from the mains for a few minutes but once it's powered up it has the same problem. I have checked to see if there are any odd timer settings (although I don't believe these would be the problem). If it has been unplugged for some time it stays on longer which make me think it may be a thermal problem - something overheating?

You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies. Good Luck

your problem is no doubt in the stand by circuitry You will have to trouble shoot your set as this is a thermal issue and you will need to do the testing of the various components while it is experiencing the trouble to find the problem. Let me know if you wat a manual. I can provide a link where you can get one .

SOURCE: My Panansonic TV shuts down every few minutes and the LED blinks three times

I still have that problem. I calle Mfr and also spoke to repair shops recommended by them and they said they estimate a cost of 300-400$ or so approx. I am waiting to buy a new LCD which could be few 100 more but at least dont have to live with the old one and keep spending money...

Check mains fuse, if this is ok it may be an internal fuse, this will be located near the input power cable and is usually a 20mm glass one. ONLY replace with same type and rating.

My matsui m32lw509 TV standby light flashes once when i turn it on then it just stays blank nothing powers up ???????????????


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

No There is no other way to get into its service mode, without its original remote control. Contact the authorized service centre for Panasonic to buy an original remote control.
