    possible purchase maxx tv

    Found this tv available pretty cheap, however I cant seem to find any info whatsoever on the manufacturer, suppose to be a plasma. Fault started with vertical lines that would come and go, then screen went black however still has sound and turns on and off normally.

    Be careful could have a panel fault and a tfp ribbon ic on tje panel can shut dowb the va voltage.
    Did I leave the soldering iron on?

      Yeah, I was thinking the same thing: Possible panel issue. Also, IMO, it's too obscure a brand to chase.

        I'd avoid it as well.

          Thanks thats kind of what I was thinking as well. Maybe I will offer to remove it for them since there is no documentation anywhere and it will likely be a difficult fix.

            Well I ended up getting this tv yesterday, they decided they wanted rid of it more than they wanted paid for it. I opened it up this morning and it is all samsung internals. The panel is S50HW-XD02, I looked over at Electrotanya and didnt get any hits for a manual. I pulled a manual for a samsung hpn5039x that uses the same panel, but has no ysus schematic anyone know where a more complete SM might be located?. The fuse is open on the ysus but I suppose it could have failed from age as this tv was built in 2003.

                I did say I didnt get any hits, but that wasnt quite accurate, i did get a hit but it was for a phillips tv not a samsung.....But as it turns out I had a fuse of the correct rating, after pulling the ysus and bufer and testing for shorts (and not finding any) I pooped in a fuse and she fired right up.

                  its a samsung so watch out for y buffer failure.probably what popped the fuse.
                  will blow up ysus too.

                    Not sure what caused it to pop in the first place but I will test it out and hopefully it stays working. Its built like a tank and weighs almost as much.

                      I don't think these suffer from such Y-buffer issues. Fuse is probably one for the 5V or 15V. Nice fix. These are well built sets.

                        Re: possible purchase maxx tv

                        Fuse was on the vs rail, but no shorts found. Ran it for about 3 hours today with no trouble so far. Top does get very warm I'm thinking a fan mod may be in order, although it apparently ran fine for 9 years so far without trouble. Too bad it doesn't have any hdmi. One other question for Tom or whomever may know, the 4 large caps on the power supply have bubbled plastic tops, but the caps underneath are flat would this be caused by the heat of the set ? Haven't seen them do that unless the cap underneath was bulging.

                          Does it have DVI? HDMI to DVI adapters are easy and cheap. Just a thought to make the TV slightly more useful

                            Yes it does have dvi as well as rgb inputs, as far as I can tell its only a 720 set. But can't say no to a free TV. I hadn't seen the HDMI to dvi adapters, just for resale everyone wants hdmi

                              Even though the TV has my name in it I wouldn't bother unless I was getting it for free. Even then... maybe not.

                                  Yeah the plastic tops do bulge with heat... that's normal.

                                    push on the bubbled tops.
                                    if they flatten out ok.
                                    if hard they are bad.

                                          Panasonic SA-MAX770PU SMPSU board fault....
                                          by Rictech
                                          Hello everyone. 😀

                                          As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                                          Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                                          Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                                          This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                                          There are no devices that have exploded or otherwise show signs...

                                          by sam_sam_sam
                                          I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
                                          I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not

                                          One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference...

                                          Hello,
                                          I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).

                                          The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
                                          On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...

                                          MacBook Pro M1 Pro Logic Board 820-02100 Mosfet where to purchase?

                                          My reference only: TT10141.

                                          Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?

                                          Mosfet specs are as follows:

                                          Chip markings:...

                                          Extech EX330 multimeter current range offset fault
                                          by PanicMechanic
                                          My multimeter has developed this fault, a few months ago. I tried to fix it, but had no success.

                                          The fault is that on the current ranges it never shows 0. Does not matter if the probes are open or shorted.
                                          As you can see from the pics, the offser is the same (just multiplied for other rages):

                                          -4.9 uA
                                          -0.49 mA
                                          -0.49 A

                                          I don't know what exactlly caused the fault.

                                          The meter had a battery leak before I noticed the fault, but I am not sure if the fault was present before that happened. I just did not noticed. The battery leaked...
