Where to buy the capacitors?

Do you have any idea where i might be able to buy these capacitors?
They are surface mount and everything that i can found around here is the normal thru hole capacitor.

Which Capacitors, You need to knowthe voltage and farad rating (ex. 16V 1000uF) they are different, If I can get the schematic then I will need the component #. Are you sure that the capacitors are SMT and not "through hole" units? Usually the Electrolytic capacitors (Canister looking things) are the first to go. They will start to swell and leak causing power problems. Do you have the unit open? Can you upload a pic of the boards?

My pump surfaced mounted 240 volts keeps tripping loss of prime after reaching pressure then drops to zero psi.Have no leaks, and pump is primed.Any ideas?


if you are running a pressure controller switch, the leak down will be in the non-return valve at the inlet of the unit
the tripping of the power indicates a problem in the motor or start/run capacitor.( I would check the capacitor for failure)

Green timer light no picture


Also known as the Green Blinking Light of Death.
The repair on this is cheap but very time consuming and wit no gaurentees.
There are 4 Capacitors on the DM board and 4 Capacitors on the Formatter board that are more than likely defective and need to be replaced.
On the DM board the locations are C81A2, C81A3, C81B3 and C81B4. They will probably be swollen.
On the Formatter board the locations are C8F19, C8F21, C8F22 and C8F27. Also will probably be swollen. The values of all 8 capacitors are the same. 1000MF/16V. Replace with value 680MF/16V.
While you have the chassi ripped apart, check the power supply board as well. You should fine some swolle caps on it also. Replace with same value of the one you remove.
Now once all of this is done and you put everything back togeather, you have a 50/50 chance of success. I have found that many surface mount caps can also go bad on the formatter board. If your repair does not work, then replace all of the surface mount caps on the formater board that are 10 and 16 volts.

Good luck to you.

Samsung R88, has no picture but the sound is working. I have checked the capsitors and they are fine any other ideas?


Check for voltage to the inverters. If there is no voltage to the inverter section, check for a surface mounted fuse and check it's condition if present.
Replace the larger value caps in the power supply as some may not show physical evidence of failure. Also remove the power supply board and check the surface mounted devices underneath to make sure there is no sign of a cold solder joint- the same on the inverter section. Good solder connections will look like a tiny volcano on the circuit board with the wire lead protruding from it- with no gaps, or areas that might suggest solder did not fully flow. Reflow solder to those connections if found. The Surface Mounted devices themselves should have smooth transitions in the solder, if not, reflow those with a soldering iron as well.


If there is voltage there, start by replacing the electrolytic capacitors in the inverter section. These will be values like 1, 2.2, 4.7 microfarad at 25 or 50 volts, These are part of the step up oscillator portion of the inverter. If that does not remedy it, check the transistors- a B&K type tester will not always give an accurate reading because the inducatnace is too low in the inverter transformer in circuit with it, so those usually need removal for accurate testing. Sometimes only one transistor needs to be removed.

If those test out okay, or are surface mounted or 4 leads plus tab versions first replace the larger value electrolytic capacitors, those will have values of 220, 330, 470, 560, 1000 microfards(sometimes higher capacities) at 25 or 35 volts. These can fail without visual indications. as they will be easier to remove than the surface mounted devices and likely cheaper too.

32 LCD tv pic went out suddenly, sound works, fuse is good, signal is good to tv


You have bad capacitors in this unit. Replace capacitor (location) 2074 which is a 25 volt 2200Mf at 105 degrees. Change capacitor (location) 2081 which is a 35 volt 1200 Mf at 105 degrees. Change capacitor (location) 2066 which is a 16 volt 10Mf at 105 degrees. And to complete final repairs change out surface mount capacitors (locations) 2H08 and 2H09. The part numbers for these two identical surface mount caps is..223886975478. And one should consider changing the color crystal, also a surface mount. The number for this crystal is 823827736071. If unable to do this yourself, find a TV tech and show them this repair instruction. Good luck and show a few hands of support.

The HDMI board on this model has problems. Replace capacitors C8602,C8096 and C8609. The acps are 100mfd/4v surface mount type. I have used 100mfd/16v radial lead type. just mount them on their side. This fixes 90% of HDMI video problems. Also remember the HDMI inputs are only viewable on the HDMI output. Also you can initialize the receiver. This will fix some problems. Although it will erase any of your settins and presets. While on hold down the vcr button while pressing the power button. The display will read "CLEAR".

What is the Product Name or Model number of your Maxent 42" Plasma TV? If it is a MX-42X3, Model # P420542HM8, I think I can help you. I have encountered this exact same problem with 2 Maxent MX-42X3 Plasma TV's. I found that C766, a 220uF, 16V surface-mount electrolytic capacitor on the main board is bad. This capacitor is located just to the left of the green multi-fin processor heat sink. This capacitor will test good using capacitor meter or an ESR meter, but if you spray it with Freeze-It with the power on, you will find out that this is the problem! To get it out, I found I had to remove the little 10uF 16V surface-mount capacitor just to the left of it. I then replaced these 2 capacitors with regular (radial), high-temperature, low-ESR capacitors. I cut the leads short, and bent the ends out just a little bit so you can solder them back onto the surface-mount pads. You can get these parts from Digi-Key Corp. I used Digi-Key part # P12383-ND ($0.32) for the 220uF capacitor, and P11212-ND ($0.30) for the 10uF capacitor. Both of these capacitors are rated for 25V and high temperature, so they won't go bad again. You can purchase surface mount capacitors there too, but I find them very difficult to solder back into those locations due to the tight placement of other capacitors in that area. If you're not an expert in soldering, I suggest you take the main board to a qualified electronic technician, and let him do it. But you better put the board in an anti-static bag before you take it anywhere! Hope this helps!

Tv flickers when first turned on. This can last for several seconds to about a minute.

AG-DS555s are plagued by capacitor failure problems on all the video boards in the deck. Replacement of all surface mount electrolytic capacitors is the solution, but before you try that, give the heads a good cleaning. It's amazing what a miniscule amount of dirt on the heads will do.

Give me hints


This model and most of the Panasonuc camcorders have surface mounted capacitors and these are what we have been finding wrong most of the time. The capacitors will become weak and start to leak goo and sometimes will blow something like a small fuse inside called a circuit protector. To find these bad capacitors, you will need to disassemble the camcorder and use whats called a ESR capacitor checker. I had a camcorder once that I replaced 27 bad surface mounted capacitors in. Good Luck.
