I don't know if you ever got a response to this post since it isn't attached to the exchanges you had with someone before. Always retrieve your original otherwise the person who assisted you is unlikely to see your reply.
BTW, if you have done this by now, did it solve your problem? Often, the larger caps are not at fault but smaller ones that handle feedback in an inverter. The main filter caps are not subjected to the high frequencies and ripple currents that destroy the electrolyte in them.

Polaroid Tla-01511B LCD TV goes blank after power up. Power led stays on. I replaced all 1000uf and 470uf 105 degree caps, no luck. What else should I replace?


have you been tried to dis able the supply going to the inverter board for the back light which may have bad parts causing the supply to drop. by the way is there any blinking lights after it turns off? it will tell you the error either in the power supply, inverter board or at the main board.

Tv off!


A lot of these sets have a problem where a "filter cap" on the board in the power supply opens---Usually location is "C925 or C926" and it will be a 1000 mfd @ 25 or 35 volts.


Let me know if you can locate it--if so---unsolder the two leads (one marked with a plus and the other with a minus--positive and negative) and replace it----$4.00 part.

Had the blank screen problem. Now it won't work above 800x600 res


When I replace caps in this model, I replaced all the caps (4 (1000uF by the heat sink, 1 (470uF) by the inverter transformer) for the 5v and the 12v since you cannot 100% relying on just by looking bulging tops. I am not sure why your has 3-470uf. See my example here: http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL2018W/

Del e173fpc 17" power light comes on but screen black.


Hello,

The issue you have is caused by a bad power supply. If you change the following capacitors on the power board you should be back running again. C925 and C924 are 470uf 16v and C922 and C923 are 1000uf 16v be sure to use high temp capacitors not just standard that you would find at Radio Shack, if you do they will blow again with in a month or two. We have a parts kit available and I will have picture posted on our web site at :

I hope this helps, if so please rate my solution.

When i switch on my P.C. and my FP 5313 screen it flickers


This is a known problem with a series of components inside the monitor. There are about 11 capacitors that if replaced will allow the monitor to function properly.

The best place to go to read more is http://www.badcaps.net/forum/printthread.php?t=2658

The list of the capacitors that are bad are below with possible replacements.

C922, C925: Hermei LE 1000uF 16V, low impedance, general purpose, replacing with 1000uF 16V Samxon GF.
C201: Hermei LZ 150uF 25V, ultra low impedance, high ripple current, replacing with 1000uF 25V Samxon GF.
C924, C926, C929, C930, C932, C933: Hermei LT 470uF 16V, high ripple current, low impedance, replacing with 1000uF 16V Samxon GF.
C207: Unknown CD110 50uF 4.7uF (general purpose), replacing with a 35V 4.7uF tantalum unit (SCP/Short Circuit Protection pin on TL1451 won't get anywhere near 35V).
C907: WC (with stylized Westinghouse W) SM 22uF 50V (general purpose), replacing with 63V 100uF Samxon GF (used for SMPS controller Vcc filtering).
C905: Hermei HT 100uF 400V, standard, general purpose, leaving as is - generally no problem.

Re: Onkyo DV-CP500 DVD player stuck in standby mode (by 7 users)


Hi Yes, sorry just saw this comment. Swap out C7, C17 and C18 in the power supply. Also I would check if you are getting 9Volts to the motor control IC's pin 7 coming off of C005 on the Mechanism Board which is under the unit. The hole for the C005 cap was drilled into a very narrow section of the circuit board and has marginal connection at best.. mine stopped working because of this 6 months after I fixed the power supply.

Dell E173FPc 17" LCD Monitor Problem:


Although similar, this monitor and the associated repair is different than the "b" version. The link above is good to follow for finding out how to open your case but the actual repair is different. If you have minor soldering skills (really the de-soldering is the hard part) and can use a phillips screw driver you can make this repair.

I contacted Tom at a link I found on the "b" site and he sent me the typical components to fail for the "c" monitor. $20 and $1.35 for shipping. The site looks to be down now so I'm not sure if this is temporary or he's stopped selling parts. He is also willing to fix the board if you send it to him. Here's what you need to do:
Replace C922 and C923 with 1000uF 35V caps
Replace c924 and C925 with 470uF 25V caps
Re-solder L201 and L202 with fresh solder.

I did all of the above and the monitor works perfectly. When you take the monitor apart make sure you note where the blue and pink wires go (you'll know what I mean when you get to that stage). The connectors are identical and it would be easy to forget which way they were installed.

I fixed my AL2021 by replacing the output caps on the power board. $4 repair. Pull the thing apart and replace the 1000uF, 680uF and 470uF caps on the end of the power board.
