    Sanyo DP52449-01 Dead, Standby flashes every 20 seconds

    Found this Service Tip, this is same symptom in my TV.

    Anyone able to successfully verify this fix? Are these chips available as well as the software?

      As far as I can tell. The software is not available. I just found a dp42849 with the same issue. I ordered the flash nand chip off of ebay and installed it with no positive results. It came with SW84. If I needed something else, I woulda been SOL. Sanyo/Panasonic never responded to my request for the firmware.

              For : kevinm34232
              P52449-01 use SW85 if IC 5700 is Samsung chip ...... SW83 if IC 5700 is Quimonda chip
              ................This will fix +80% of the boards with the symptom below...........




              IC5750 needs to be replace.
              Hynix HY27US08561A-TPCB TSOP 48 pins IC Chip
              Flash NAND 256Mb (x8) TSOP 3V


              But ...but..... 50' and 52' Sanyo TV have the symptoms look like same problem , so u need step by step troubleshooting.......

                  I'm pretty good with a soldering iron. I checked with a loupe. All pins were soldered with no bridges.

                  My plan is to hold onto it in case I find something with a cracked screen that shares the panel. Why, what do you need?

                      Peter are you saying that is the correct chip in your post?
                      Sanyo says it is out of stock when I try to order it from them.

                          Vizio D50u-D1 Dead Set No Standby
                          by fharris1977
                          Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

                          Insignia NS-LCD019-09 issue: Power light turns blue for 3 seconds, the flashes red before going solid read again
                          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...

                          Sony OLED XR-77A80J - Initially dead, now 4 Flashes
                          by thstuff
                          A) TV initially dead
                          B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
                          C) Was able to perform a Reset from Settings menu and completed out of box configuration.
                          D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
                          E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical...

                          LG C1 65'' dead standby
                          by jacobtc
                          I've owned this C1 from new since late 2021, and it has now suddenly started with the following symptom:
                          If power has been connected for a while, the red standby lamp turns off, and the tv wont turn on (no reaction from remote or button on tv).
                          If power has been disconnected for 5 minutes, the tv turns on fine, until turned off and left for a couple minutes, as the standby light will then turn off again.

                          I've seached and found that this is most likely a failing PSU, and I've seen repair services on eBay fixing these symptoms, so I am hoping that someone here has fixed...

                          QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
                          by mecha1166
                          I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!
