How do I go about testing my POWER SUPPLY BOARD (sos-p) for defects?

PANASONIC TC-P50X5 POWER SUPPLY BOARD (N0AE6JK00006), how do I go about testing my sos-p board for defects to make sure repair or replacement is what I really need to do? Breaker flipped off, TV no longer turns on nor does any light. Did the un-plug/plug in, wait 5 min/1 hr/2 day deals and still nothing. Pulled back panel and ready to pull sos-p board, but want to test for the problem first.

Visual of board may give clues like a puffet top or end of a cap. other parts may look like they have been hot.

Your problem is most likely the thermistor , or degausser, is going bad. It is a little black box with pins and says D1R5M on it. It can be found by following the wire from the degaussing coil around the picture tube. The location number is CF803( i think)the Panasonic partnumber is D4DF1R50001. Also, I believe your fuse is 6.3A not 3.6A.

Hi! I am sorry to hear about the frustration that you experience from the tech support of dish network. If you already talk to this guys for 90 minutes do different troubleshooting steps, Did they ask you if your receiver is plug in to a power strip or surge protector? If your receiver is plug in to a surge protector or power strip, please unplug it from the surge protector or power strip for 1minute. then plug in directly to the power outlet. Sometime the power strip or surge protector dont give the 100% current needed by the dvr. just to isolate the problem, connect the dvr to the power outlet and plug in after 1 minute. if the receiver dont boot up it just turn on the green light and turn off by itself. there is a problem from the power supply of the dvr. just in case it turn on and it shows attention 015, press the menu button on the remote and it will show the main menu, press 6,1,1 on the remote and it will go to point dish,once its on point dish, selct check switch, then on the next page selct test, it will run the test up to 1 of 3 or 4 it depends on the condition of the sat dish, once its done, it will show the installation summary screen, it should show the 3 sat or 4 depends on how many you have, ex, 119, 110, 129, or 77, 72, 61.5, once all sat are all ok, selct done, then select done on the point dish and cancel all the way out of the menu and you will see attention 015, it should finish the progress and download the programming guide, and it should show a picture on the tv screen, just in case the problem still exist, call 1-800-333-3474 and ask for a supervisor and explain to the supervisor that you talk to the tech for 90 minutes and also tellthe sup that you did the troubleshooting step that i mention to you but the problem still exist.. the problem is with the dvr, pls feel free to get in touch if you have any query..

Before you replace the power supply , check for swollen(rounded top)capacitors.
Also check and replace C126 47mfds/50 volts

My panasonic tc-p50x5 will not come on after power outage. whats wrong?


Being in the field of electronics I can not stress this enough....POWER SURGE PROTECTION...and I am not talking about a power strip with "surge protection"...they are useless. That being said you had a surge that most likely blew out your main power board. There is a fuse on that board and if you are lucky that popped and it is an easy fix. If not, you will have to remove the board, get the numbers on it and search out a replacement. There are plenty of places online to get them but I use Allied Electronics. One thing to check while you have the tv apart is to check all boards for visible burn marks or damage from the surge.

Why won't my TV power on?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Panasonic tc-p50 X5 wont switch on no red light


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Won't come on after power outage


hi is it totally dead if so it's possible the fuse inside could have blown, this will be on the power board, glass type, if it has and you replace it and blows again then there's a dead short on the power board or on main board hope it helps

Panasonic TH58PX60U TV comes on for 5 to 15 minuets and shuts down with 4 red flashes on trouble code light. Is this the power supply board?


4 blinks Power SOS P Board
Try opening it first look for some bad connections or so if they are none use a hair drier and heat the board looking for the place that creates the 4 blinking then use the hair drier on cool to cool the place and get this time little longer.
