    52"RCA Problem.

    RCA 52"
    Model# LK520D3HA88-QYE

    The problem I am having is when you plug the tv in I get a red led As soon as i hit the power button the led goes out and then there is a flash. and then nothing. no sound, no pic.
    All the caps look ok no burns on any of the boards all solder joints look good. What should I look for next.

      what do you mean by a flash? did you check the voltages for the connector on the power supply when the light is still red?

          so it tries to turn on then shuts down completely? did you check the voltages on the connector on the power supply?

                  can you check the small cap in the center of the board to be sure it isn't bulging? the pic is kinda fuzzy

                    That cap looks good no bulging. That is the model # on the sticker here is another # on it a01301xpqy00001326.

                      Where are you from? The model number and the part numbers that I can decipher don't show up on any google search that I do.

                        Minnesota. I am having trouble finding boards for this tv to, I thought it was because it was pretty new.

                          First thing I see is that the LVDS cable at the TCON is not on correctly. Also the power supply seems to be getting it's power on voltage but isn't putting out any 12 or 5 volts.

                            Having trouble finding boards for a new TV is not uncommon. Not finding a single advertisement, review, or website that even mentions the set is uncommon. Could you post a picture of the label on the back?

                                Sorry for the confusion. I was actually referring to the label on the back cover. It might have the date of manufacture and the chasis number as well.

                                  That is my fault This is the model#on that sticker and the manufacture date.

                                    OK, so we're looking at an RCA LED52B45RQ. Manufacture date of 12/12?!? Did you buy this new? You may have a warranty that will take care of this.

                                        Sounds like a nice friend. We can test the power supply to weed that out of the equation. With all of the connectors plugged into the supply and the TV plugged in but not powered on, check the voltage across the big cap. Black lead of the meter on one leg and red lead on the other. It should read around 165V. Power the set on and check again. If that part of the supply is working, it should read around 390V. If you can post clear pictures of all the connectors on the power supply, I'll try to help you attempt to force the supply on using two resistors. I need to be able to read all of the labels for each connection.

                                          Nikon D800 camera - flash don’t work and capacitor don’t charge
                                          by corrize
                                          Hello, I'm stuck in troubleshooting…
                                          The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

                                          In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
                                          When I press the flash button, it's detected by the system, flash icon appear on LDC display....

                                          Problem with LG Plasma 60PM6700 - Random power downs
                                          by theone111
                                          I have an LG Plasma TV 60PM6700 for the past ~12 years.

                                          In the last ~3-4 months I have been having some issues.
                                          1. Problem: It started with random picture disappearing (sound still worked).
                                            Frequency: Happened about once a week.
                                            Solution: Had to turn off TV wait a few seconds before turning it on again.
                                          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                                            Frequency: Happened about once a week.
                                            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                                          3. Problem: TV shuts down
