Re: polaroid tv capacitor identification

Ok. Now I'm looking at the browns ones and they look different too. I guess I wasn't carefully enough in getting the same parts. Do they have to be the same size as the originals? I will post pics.

Re: polaroid tv capacitor identification

I got my caps in today. I ordered the two brown ones and the big one suggested in post #94. The big one looks to have leads that are too short. It is also bigger around and a tad shorter. Anyone have a better suggestion for a part replacement or will this one work? It says 105C 150uf 450v 1326U on the one I received.

Re: polaroid tv capacitor identification

Hello, I just wanted to say thanks to everyone who takes the time put post an amazing amount of info here! I have come across this site many times and it helped me on 2 lcd monitors, With that said I knew it was time to join. I'm currently working on a Polaroid TLX-03210B that I got for free, it has the constant red light on in the front, no response to any buttons or remote, Caps all "look" good (do not have ESR) the big 150@450V cap looked bad until I learned here that it was normal. There is a red light on the board itself should that be lit? I'm gonna continue reading through post! Thanks

Re: polaroid tv capacitor identification

The large capacitor in this TV has a plastic covering on it that bulges outward, it may not be the actual capacitor that is bulging. See my post #94.

Sorry about that. Doing this post from my iPad and it won't let me upload pics. Thanks. I have ordered them and we will see how it goes. Thanks for all you who post this valuable information.

I found these cap bad in my TDA-03211C but wat about the large one. It looks like it is bulging too. I will try to upload an image.

Re: polaroid tv capacitor identification

Just wanted to post an update also and say thanks for all the info I obtained from this site, and to Plainbill a special thanks for not treating me like a "dumb ol' girl"... lol I replaced the two 10uf 450v caps on the tv on Thursday evening (11/03) and the tv has been working great ever since. I purchased the Panasonic brand from Mouser, ended up just getting the regular ones, not the high temp ones I asked about, spent a total of $6.13.... can't beat that for a free tv that I "rescued" from the trash heap... gave it to my mom and she is happy as a dog with a new bone... lol Now, if I can just teach her to use the universal remote.... Thanks everyone for all your help.... Oh and for my first time soldering, I think I did a pretty bang up job.... :-)

Thanks again, Lisa

Re: polaroid tv capacitor identification

I recently received a TLX-03210b from a local electronics recycler for free. It was stated that the picture would come on and then slowly fade to black. I plugged it in when I got home and found that the center one third of the screen appeared darker than the outer thirds and then the screen would go blank. I opened the back of the tv and found one of the two 10uf 450V capacitors to be bulging and the other flat. I ordered 2 10uf 450V capacitors from digikey (http://parts.digikey.com/1/parts/50022-cap-alum-10uf-450v-20-radial-eeu-ee2w100.html). I also ordered the main capacitor at the same time as it appeared that it may be domed (although all of the main capacitors on this board appear to be like that from pictures posted here) (http://www.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=p11674-nd). I received the parts today and installed the 2 10uf 450V capacitors and put the TV back together. TV has been on for about 2 1/2 hours now with no apparent issues. I did not replace the main capacitor, but I have it just in case. Total cost for the two capacitors was $2.08 plus $2.22 postage (main capacitor was an additional $3.91). Just wanted to give an update so that hopefully someone else can find this information useful.

Thanks to everyone on badcaps.net for all of their help that I have gotten since joining this forum.

Re: polaroid tv capacitor identification

I'm new to this forum, and to the "fix it" myself world - I have one of these Polaroid tv's and the two 450v 10uf caps are bad. In reading all the info on this thread that you tech guys have generously shared I have a question....

If heat seems to be the problem causing these caps to go bad would it be better to replace them with High temp caps of the same value? I looked the part no. up on Mouser that Abblepc posted, and noticed that they also have another that is "high temp".... would they be better to use?? Or am I way off base assuming that high temp means just what it says? lol This is the link showing a side by side comparison of the two caps.... Other than the diameter I don't see much difference... but then I am a novice....

Thanks for any advice/insight you can share....

Using caps rated for higher temperatures and low ESR would be good, but it really isn't necessary. The problem is certain brands of caps (Capxon, Lelon, Elite, etc) have a history of failing in certain applications. Other brands with similar ratings (Panasonic, Rubycon, Nichicon, etc) have a history of not failing in the same applications.

Re: polaroid tv capacitor identification

Thank you PlainBill for fast response on this. Does anyone have the complete part listing with part numbers for the replacement parts either through Mouser or digikey. Noticed that Digikey doesn't have as big of a selection as it used to but I guess thats just where I am looking.

Here you go...

2 FQPF9N50CF (Q16,Q17) *Mouser Part #*512-FQPF9N50CF

2 10uf 450v Capacitors (EC17, EC18) Mouser Part #*667-EEU-EE2W100U

1 3.15 amp fuse (F2) Mouser Part #*576-08773.15MXEP

That information may be somewhere in this thread, you're probably going to have to look for yourself. If it isn't, pictures and dimensions of the caps and fuse will help select proper replacements.

Re: polaroid tv capacitor identification

Mouser has the transistors, and should have the caps and fuse. Digikey doesn't have the transistors.

Re: polaroid tv capacitor identification

Yeay I fix my tv, polaroid TDA-03211C (powerboard ipos 150 rev 1.8 Proview) -Had audio but no pic and a red Led light blinking it the back.
For reference of how I fixed it I replaced
2 10uf 450v Capacitors (EC17, EC18)
2 FQPF9N50CF Transistors (Q16,Q17)
and a 3.15 amp fuse (F2)
(thank you Dansford, PlainBill, and retiredcaps)

Sorry still learning boards but this is the post I am talking about

Re: polaroid tv capacitor identification

Ok I am new here and noticed that this is a dead thread but was wondering if anyone of the above noted people still have a listing of where to get those parts and where the fuse is located on the same board as mentioned about in Lucky19's last post.
Also has anyone done a write up or know who to install a better cooling system to these TVs every repair shop here in AK are telling me that the major issues of this TV is that it gets too hot and starts burning parts up.

Re: polaroid tv capacitor identification

That is an IPOS 150 board, I just repaired one this past weekend, and yes those are rated at 10uF 450V you just need to get some better quality caps.
