Hello folks.
I bought this machine brand new. It ran fine for nearly 6 years. Lately, it has been plagued with random shut downs without warning and I have nearly pulled my remaining hair out trying to troubleshoot the issue.
I have no electronics knowledge though if anyone can guide in the right direction this would be awesome.
Description:
----System will randomly turn off. There is no specific timing. Sometimes it can run normally for a couple of days without the issue but once it starts; it becomes more frequent, and then it sort...09-19-2023, 12:51 AM -
Trying to fix a backlight problem with a Sceptre 48" TV.
I found replacement strips with the same part number as the strips in the Sceptre, but the new backlight strips have 5 leds per strip and the ones in the tv has 6.
So I decided to replace the leds instead. I found 3 bad ones. I had no problem removing the bad ones with a heat gun, they came right out. However the leds on the replacement strip would not come out with heat. I use my solder iron as well, they will not come off.
Anyone know how I can remove those leds without damaging them? -
Hello all,
I have a Sceptre X505BV-FMDR8HJ1PE8 tv that had been gradually over time taking longer
and longer to come on, now it will no longer display any image. Original symptoms
are the red standby LED would turn to blue immediately when pressing the power on
button, but there would be a delay for the "SCEPTRE" image to appear on the screen
and backlight to come on. The delay kept getting longer, then it would go from blue
LED back to red. Then when I pressed the power on button again it would bring the
display up and work fine.... -

Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this... -
Hello everyone.
I have a device that is used to shape the human body muscels and burns fat. Works on the principle of electromagnetic impulses. One thyristor in side is shorted which has only this unknown mark on it ( QC230301 ). I can't find any information about it anywhere on the Internet. I tried to replace that thyristor with one of 1.6kv 800A and after 5min. of work he has burned out again, which means that he is probably weak. There is no schematic diagram on the internet, but that didn't suprise me because all the transistors and chips that are on the boards have their markings...
