    46LA45RQ 2 CCFL's not lighting up

    So I opened her up and found that 2 of the top ccfls are not lighting up. When these don't light up it turns off in 2 seconds... I have seen many threads on this TV, and saw one about a ground but I dont see any of the bulbs coming out or not being grounded. What could make this happen? Thanks,
    Zack

      After inspecting more, I believe one of the transformers on the inverter board is going or went... one part of it has a smoky white liquid material under the tape where the copper wire is wrapped around it. All the others do not have this...

          And holy crap, after searching my parts warehouse (Closet) I had an inverter board in there from a prior TV, and it WORKS!!!!! OMG! So excited, I spent $50 on this broken one and fixed it within an hour!

              Remember to check Inverters when CCFL lamps in a certain area are not working people!

                  Lithonia Lighting versus Light of America Compact Fluorescent product quality
                  by sam_sam_sam
                  I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

                  I also have back when Light of America had these light bulbs available for yard lights

                  The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

                  While the Lithonia lighting fixture has all most certain bulb failure

                  So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

                  I have only had this light fixture for not more than a year if it...

                  Aiwa Z-R700 Music System has very low power when switched on, dim lighting and nothing works
                  by pecman
                  I was given an Aiwa Z-R700 from the 1990s era to look at by someone who said the twin tape deck did not work. The whole unit unit powered up ok but there was nothing from the tape deck. I had a look and found all the belts broken, I replaced the belts and then put the tape deck back into place and it still does not work. Also when I now power up the unit all the lighting on the front is very dim and the cd player and the tuner as well as the tape deck do not work. I have checked all the connections and ribbon cables again, there are no burnt or swollen capacitors. Maybe there are capacitors on...

                  Trying to determine a fault, not sure if the culprit is LM2574 pin 7 output is grounded
                  by repair-it
                  I'm not sure if this is correct, the output pin 7 is grounded or the ic has a short. I'm just trying to rule it out. https://www.ti.com/product/LM2574?qgpn=lm2574

                  LED lighting batten drivers
                  by onextwo
                  Hi,

                  In my workshop I have 12 LED lighting battens and the some of the drivers have failed.

                  In side there is 2 aluminium PCB with a 72 LED on each PCB as ‘current' Schematic.

                  I am looking the get some constant current led driver to replace them.
                  is it there any problem wiring as ‘option 1' Schematic or is it best as ‘option 2' Schematic.

                  With option 2 I would have to modify the all PCBs, so a lot more work.

                  Vanquish CMH lighting system Controller Board
                  by Gadjet
                  Ok so let me run you through the chain of events, the controller stop coming on no video, after checking the board they were lots of shorts on the board. I removed the screen a couple disappeared, then I removed the cpu and more disappeared, lastly I removed the memory chip and all shorts were gone. (The 2 chips circled in red are the memory and cpu) Also there is an issue with the 5v test point that is circled it’s reading 12v and so is a 3.3v regulator next the power jack.

                  Ordered a new CPU and Memory chip and installed them, reconnected the screen and all shorts are gone. Reconnected...
