    Westinghouse LCD? TV only has little blue light nothing else!

    After a power outage at Simrah Gardens in Hudson, Massachusetts, the TV only has a little blue light lit on the front.

    The TV was brought to Vermont.

    I checked the symptoms today, at my weekend worker's house, in Bellows Falls, Vermont, the same town I grew up in.

    I was thinking maybe a fuse.....

      Would help if we could have some pics of the psu board. That is where I would look first, with these symptoms.

          And a blown fuse would be unlikely to cause a standby light but no power, unless it was on the low voltage side.

              My 55" Proscan, that I had already repaired(caps) and was using in my living room died from a power outage recently. It turned out that a MOSFET had shorted and it's back up and running. It's worth checking them out I think.

                  Lovely! Especially if I have a hard time reading the MOSFET specs.....

                  Getting the back off is expected to be a bitch!

                          I'm not at the worker's house in Bellows Falls. It was brought there.

                          Sorry, didn't get a chance to even read the model code.

                          Didn't even get a chance to read the manufacturing year, LOL.

                          I don't even have a multimeter and I don't want it to get thrown away!

                              Looks like he chucked it!

                              It seems to have gotten spiked! (power spike) T-storm-like damage, even when it was wintry weather!

                                  Nintendo 2DS XL – Orange light, no blue light, signs of overheating
                                  by Tomylee
                                  Hi everyone, I have a Nintendo 2DS XL that shows the orange charging light when plugged in, but nothing happens when I press the power button — no blue light, no screen, no sound.

                                  Here's what I've observed:

                                  All ribbon cables are properly connected

                                  Battery is present and in good condition

                                  No reaction even with screens disconnected

                                  There's a visible burn mark / overheating sign on the metal shield, right above the CPU


                                  I’m suspecting an issue with the CPU, PMIC, NAND, or a power...

                                  After being plugged in, red light comes on. Push power button and blue light comes on for ~five seconds then goes out. Power button does not turn the unit on a second time - have to unplug/re-plug before power button will try to start with blue light.

                                  No sound, no picture (used flashlight test).

                                  No bulging cap, no burn spots, no burn smells, nothing visual (cold joints/breaks/bugs).

                                  PS5 EDM-033 Blue Light 2 Sec then Powers Off
                                  by TurboTundra
                                  Hi, I am waiting for my uart tool so I can grab an error code and narrow down where my issue is, but I decided to measure capacitors and fuses to insure everything was okay.

                                  The PS5 turns on with a blue light and a beep for 1-2 seconds then turns off. I noticed a grey capacitor measures no voltage on standby or input power. Does this indicate a problem with the capacitor or something down on the line? I’m getting 3.3v on input with the red cap next to the grey one, and 5.2v on input with the red cap further away from the grey cap.



                                  Thank you for any input...

                                  by cajoeg
                                  Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

                                  The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...
