    Starting from scratch with Mitsubishi DLP problem

    I have a Mitsu WD65734 DLP TV that is giving me a steady red status light on front panel. Everything I can find online points to either a cap problem on PS board or a lamp issue. Can anyone enlighten me as to which is more likely?

    Thanks

      I have no idea, but if you open it up and look at the PSU you should be able to spot any failed capacitors.

      Uploading some photos here would be useful, and should help you get help

          So I learned how to get error codes - came back an error code 48 which evidently indicates a problem with the PWB Main board. Now the question is whether or not the PWB Main board is one that has bad capacitors, or I just need to buy a whole new board. Any ideas?

              Well...I'm not sure where you would just get a OEM board. Maybe they make replacements? Well, you'd have to do a visual inspection. If any of the caps are bulging, leaking, or just look strange, it could be the reason. It depends on how many have gone bad I guess. And if anything else looks messed up...

                  Don't forget that in a faulty system any error codes may in fact be wrong because of the fact that there is a fault somewhere.

                  The fastest way to know if there are bad capacitors is to open the thing and look at them.

                  If anything looks suspicious, upload photos here, we can see what's what...

                      Thanks for the feedback - I'm going to open the set up tonight and begin inspecting things. Probably start with primary power supply. If it's bad, who knows what kind of error code would appear.

                          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

                          i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
                          The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

                          Lenovo T580 - LCD Panel problem - error 0288
                          by perzyk23
                          Good morning,
                          I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....
