    Rca 42pa30rq troubles

    I'm trying to troubleshoot this RCA 42PA30RQ. It clicks on then clicks off right away. I did the disconnect test and have narrowed it down to the T-Conn board (I think) When the T-Conn board is disconnected from Power Board it only clicks on. When connected on then off. Tried disconnecting all the other connections to the T-Conn but still click on click off...Bad T-Conn? Or? None of the other boards affect it connected or not.

    Serial Number: 1357-42PA30R-A112332 MFG DATE: NOV 2011

      Most likely, Y-main/X-main/Y-buffer fault.

      The controller / T-con will send the on/off signals, but just because these go away with it disconnected, does not mean it is bad.

      Do you have a digital multimeter available?

                  After replacing the ymain, xmain and y buffer it works like new...nice tv. It also has the tuner that will get the hd cable channels we have here on channels 1005-1011 without a cable box.

                      Acer Predator Helios 300 - will not power up if battery is CONNECTED
                      by survivalbloke
                      This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

                      820-2915-A Wont power on with battery connected
                      by beogeek
                      Ok so this doing my head in and hopefully someone more knowledgeable will be able to assist.

                      I've got a MacBook Pro 820-2915-A it will power on without the battery connected, but when the battery is connected it will do a 2,3-second fan spin when pressing the power button and then nothing.

                      After measuring and probing around I found that R7051 was bad, reading high instead of 2.2Ω so I replaced it. Still the same issue, I have the green light on the charger but it won't power on or charge the battery.

                      So to cut the long story short I've replaced U7000,...

                      PS5 too many USB devices connected
                      by muhuruu
                      Hello. I have a problem with a PS5 console that I bought to learn electronics repair. The auction description indicated that the console had been dropped. The HDMI port and USB ports were damaged. The HDMI port was replaced by the previous owner, and after his repair, the console worked for 2 days and then became dead. After receiving the console, I replaced all the USB ports. After replacing them, the console started to turn on. On the logo screen, it displays "too many USB devices connected". My further attempts to fix the error involved replacing the Southbridge, 4 TPS2001D chips,...

                      Weird problem, laptop stays on when connected to another pc
                      by versionlab
                      Hi, I want to ask for advice about an interesting issue I've been having with a sony vaio laptop.

                      Client came and said that "a desklamp touched the back of the lid while laptop was operating normally and it caused the office's circuit breaker to trip. Laptop had never turned on since".

                      After taking the laptop apart (checked dc adapter everythin ok), I found a faulty MOSFET on the motherboard which I replaced. Laptop managed to turn on. However, while booting it shut down. Nothing else seemed faulty and thermals were ok. Shutting down was coming at random...
