    Re: Taking apart a gv42l and troubleshooting

    Now I am beginning to see the later model of VIZIO with bad EEPROM in the TV threads, that is more difficult to troubleshoot to find out if it is firmware or hardware problem.

        Re: Taking apart a gv42l and troubleshooting

        I remember seeing Vizio TVs at my local Costco about 2.5 years ago. What caught my attention was the box proudly said "Designed in the USA".

        I wonder if Costco is now regretting carrying Vizio with all the problems with their generous warranty.

                The terminal may be removable if you can see the exposed locking pin on the other side of the body.

                            Not easily, I fixed them by removing the terminals, spread the crimped section and solder the wire to the terminal. Or you can solder the wires directly to the board.

                                Service manual has a Bill of Materials. Look through the drawings to see what the part number is and maybe you can order a replacement or find equivalent on ebay or digikey.com

                                Use Chrome or IE with adblocks disabled, wait 60 seconds and the "Get Manual" should appear



                                Look for

                                            Thank you guys so much. I've probably been a bit of a pain but after all this I've learned a lot. I even found replacement cables. All I had to do was think outside of the box and get proprietary cables from a vizio set. Ebay worked wonders. I'll probably buy more broken tvs and have a hand at it. Of this same model.

                                                mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France. I have been a computer network system administrator and a corrector of administration modules for automated programs under Unix. But I really miss the practical "ops" side of troubleshooting. So I would like to start from the beginning: 1.8V, 3.3V, 5V and 19V tests for example, etc...

                                                The issue with this video card is the HDMI port. Specifically on pin 19 (Diode checks on all other pins are normal). When i do a diode check on it from the pin on the board itself, I have nothing. There is also no short on the pin. Resistance reads about 200k. Normally on any HDMI pin 19 I would expect some voltage drop anywhere from .5v to 1.2v but here, I have nothing. The card is operational and can be used via the displayPort ports, but not through the HDMI. Attached you will find the pdf schematics for the card on page 22. I have verified that all of the resistors on this line before the...

Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...

                                                Troubleshooting Old Chiefmax 650Watt ATX Switching Power Supply
                                                by Zippie
                                                I’m looking for some advice troubleshooting an old Chiefmax 650w power supply in a PC, if it’s advisable to dig into it.

                                                Worst case I can replace the PSU, I’m just interested in learning the troubleshooting process. However, it’s out of my area of expertise and I could use some direction.

                                                During PC operation I heard a loud pop noise, like a cap gun and the tower lost power.

                                                Initially there is no power output 3.3v, 5v, or 12v when jumping the power on pin to ground. Also, no fan power.

                                                Opening the PSU the only things visible initially...

                                                Dell Lattitude 7424 Broken USB-C Port

                                                Hello!
                                                I run a dell rugged extreme as my main computer, and have linux installed. All is well! However, after plugging in a friends power adapter to test it (it turned out to be broken), my USB-C port has stopped working. This isn't the end of the world, since I can still charge with a good old-fashoned 19V barrel power, but I'd like to fix it.

                                                The port shows up to the operating system, but does not provide power to devices plugged into it, nor can it receive power. I have tried cleaning it.

                                                I strongly suspect that the physical port itself is damaged, and would...
