    Panasonic TS-HA, TS-HB, TS-HC, or TS-ED. Look at the data sheets for those series and find your cap value in the right size.

    Chemicon would have the proper cap too but I can't remember the series. Just search for the value and voltage and they'll come up.
    will this one work? http://search.digikey.com/scripts/Dk...name=P14104-ND

      Re: polaroid tv capacitor identification

      If the width, height, and diameter are correct check the lead spacing if everything matches up yes.

      Measure in millimeters from the center of one lead hole to the other that spacing will be listed on the datasheet.

        Well now that i took the caps off for a better look at them I cant shine a light to it. Any idea were to find the inverter at a cheap price?? And how many are their?

          The inverter APPEARS to be on the power supply board. There is a serious shortage of decent pictures in this thread. First you have to establish if (and why) it is misbehaving. Then you must decide if it is possible to repair it.

            Hmmm... from this u-tube vid they seem to be next to the caps that go bad.

            Seems like if i buy a whole new power board less of a headache.

                Yea your right then its an never ending circle.

                So my research came up with this quote, "check the diode at D10. This power supply often has a bad diode which can contribute to problems. If so , an EGC 576 might be a good replacement."
                Were can I find this ECG 576 diode to buy???

                Also a fuse at F2 which I have checked and getting no response. Description on it after removing some green shrink wrapping it shows F3.15A 250v ceramic fuse with pig tails.
                Can I find this at any radioshack and is it a slow or fast burning fuse??(this one looks like it might solve my problem)

                This person has the same symptom as my tv.

                  It's ECG576, not ECG 576. Google is your friend. It's a 400V 5A ultra fast recovery (35nsec) diode. If it's a surface mount diode a Diodes, Inc PDU540 is an exact match. It's available from Digikey.

                  Define 'no response' for the fuse. If it's open, that fuse is also available from Digikey.

                  I always point out that help is a GIGO (Garbage In, Garbage Out) proposition. The better the information you give us, the better the help we can give you.

                      Here's the problem I'm facing. I know virtually nothing about you. I don't care if you are young, old, tall, short, male, female, white, black, green, yellow, or red. None of those matter (OK, green would be sort of cool).

                      I also don't know how much you know about electronics. And that is important. I've seen self proclaimed experts trying to measure resistance with one meter lead in the Amps jack and the other in the positive jack. I've seen self proclaimed newbies with decent oscilloscopes and excellent knowledge of how to use them. I've seen trained technicians try to use a DMM to measure the resistance of a .01uF cap!!!

                      When you say "I checked it and get nothing on the multimeter." I don't know if you measured it's resistance and got .3 ohms, measured the voltage across it with the power on and got .01 volts, or did something unimaginable. I could hope you checked it's resistance and found it acceptable, but at this point I would rather hear something like "fuse's resistance was .2 ohms", or even "I know how to check a fuse, it's good. "

                      If you wonder why I care, recently we had a thread that ran to over 150 posts. The power supply in a monitor wouldn't start. Probably a dozen people got involved, most with excellent suggestions, some with crazy ideas. All caps were replaced, the SMPS controller was replaced, all diodes were removed and replaced, I believe even the power FET was replaced. The actual problem? A shorted transistor in the inverter. I would rather avoid this thread running to 5 pages only to hear "I thought a good fuse would read open."

                      NOW, earlier you had mentioned D10. Have you checked that? Remember, fuses usually blow for a reason.

                        Re: polaroid tv capacitor identification

                        D10 is the diode I have no idea how to check it, and yes im at total noob at this. Im usually under a car, but im a do it yourself-er and like to learn new things, it why ive tooken up the challenge of fixing this POS tv. ECG576's suggestion to replace d10 diode is totally different. From what I can read off it is J718 R303 round with pig tail on each end.

                          To test a diode in circuit,

                          a) put your multimeter in diode test mode
                          b) put your black lead on one side and the red lead on the other - record reading
                          c) reverse the leads - recording reading

                          A good diode should read 0.4V to 0.7V in one direction and 0L or "1" in the other. If you get a reading in both directions, you will have to desolder one leg and retest to verify.

                            And one of the little ironies of electronics labeling, a diode with leads is usually referred to as 'leaded' or 'through hole', while a fuse with leads is 'pig tail'.

                            As far as D10, do the checks retiredcaps suggested. If it is bad, the ECG part is available online.

                              yea d10 looks like its good (.433 in one direction 1 in the other)
                              I have ordered the caps @ EC17, EC18 already seeing as how every were I went they mentioned about them.
                              The fuse I've been checking for resistance, meter show to stay at 1 which i assume it indicates its bad.

                                If the "1" is on the left hand side of your multimeter, the fuse is open (bad). "1" on the left hand side indicates out of range or infinite.

                                A good fuse should read less than 1.0 ohms.

                                1.0 ohms (a measurement) will show up the right hand side of the meter.

                                  Ok back from work. I received my 2 caps today waiting on some transistors, and now looking for this fuse. I looked it up on digikey by typing 3.15a 250v and get alot to choose from. I think its these S505-3.15-R. I hate to ask but any links to the correct ones??

                                    A clear focused picture (using manage attachments and not posted inline) of the old fuse would help. Also, measure the dimensions of the fuse.
