    Re: Philips 42" 715T2432-2 issues

    Thanks for the info Ron. I have seen those kits. I already did the main 3. Looks like i will order the rest of the caps and the 2 diodes this weekend and give it a try.

        Hi Mavrick2k,
        did you resolve this ? I'm at the stage of replacing the Zeners ZD904 and ZD902, I'm also replacing the rectifier STPS40H100CW, Dual Schottky Diode, 40A 100V Common Cathode, Dual, 3-Pin, TO-247 at D922, I've ordered most of the caps as well.....getting fed up with this PSU....seems like its a common fault, just wondered if there was a iron clad fix for it....other than trial and error

            I had not reordered parts. I got busy and had not had time and then i did some more research. Seems like people do get it running again by replacing majority of caps and zd902&904. One post had stated the Q902 - Shorted. Got a new meter that did capacitance so tried testing a few caps. pulled five off the board and all five tested bad. Then tested with a friends meter with the same. Thought about getting a esr meter but dont want to spend the money for as little as i would use it. I tested 922 and got a short. So I am putting in the order now for 11 caps 2 diodes and that rectifier.

                I've resolved the issue with the power supply I had, same issue chirping on startup/load I've replaced the following parts and now have a working PSU

                C953,C952,C951, C955, and the big 220uf 450V cap

                ZD904, ZD902

                D922

                (5 caps 2 Zdiodes 1 rectifier beats your 11 caps 2 Zdiodes and rectifier ....<grin>)


                Just thought I'd pass on my success on this repair (your mileage may vary)

                    I've got to say I'm appalled at Phillips the company they are about as much use as a chocolate fireguard when it comes to helping the end user.....that's the problem these days with this throw away society we live in .....its' a shame

                        I orderd 11 caps because i figured to go ahead and get rid of all the crapxcon while i was at it. I did not order the big one though and I did not test it. Was yours bad or did you replace it just because. I prolly should have ordered it as well.

                            Well I replaced everything. Tv Fired up fine went through menus. I got excited went out and got a wall mount for the bedroom. Mounted the sucker hooked everything up and powered on. Damn thing started chirping again

                                                I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                                                For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                                                It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                                                Can't find exact matching caps for replacements, what should I get to prevent video issues?
                                                by SluggerB
                                                I have an old Tivo. The Power Supplies are known to have caps that fail. Here are the caps that come with the original power supply:



                                                I could not find replacement caps with the exact same specs. I followed an online guide and recapped the power supply with caps with these specs



                                                The power supply now works, however the HDMI video is giving me eye strain. I don't know how a capacitor on a Power supply could impact an HDMI video signal, but it does, the Tivo interface has a flicker now and the color/brightness is off. So I want to get some new caps...

                                                Hello,

                                                First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                                I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                                I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

                                                Hello!

                                                I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                                The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                                I have studied the board and...

                                                I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                                I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
