I would suggest to use PANASONIC FM or FC series from DIGIKEY, they have low ESR, high ripple current capability, 105c rating. You should replace then as set per suggestion above.

Redhorizon77, Electrolytic filter capacitors are relatively cheap. I would at least replace ALL filter caps that have the same capacitor manufacturer name that is printed on the heat-shrink "tube" label. Look for names like: "CAPXON" SAMXON" "JUN FU" "ELITE" Then tell us what you find installed on your SMPS board. Please pay attention to polarity when replacing them. The wire lead closest to the white stripe on label is the negative lead. Make sure to mark the board with fine point marker where the negative lead goes!! And take close-up photos (2 to 3 inches) of board and capacitors BEFORE removing them. Solder some half-inch leads onto the bad and suspected bad caps and ask the local tv/monitor tech to measure the capacitance value (UF) microfarad and report back the data here on fixya. Also tell us brand of filter caps you installed. 12fixlouie

    redhorizon77, I looked at your pic's and can see you will need to replace a whole lot of CAPXON caps. I wouldn't trust them as far as I could throw a 1 ton wrecking ball. Replace with 105 deg C rated caps. Not 85 deg C !!! The caps I have I measured on a Stanford Research Systems SRS720 LCR meter. A Capxon 2200uf 10v read 10.8uf , 2200uf 16v read 119uf and three more were just as bad!!! 12fixlouie

My LG Plasma TV will not power on.


- You still have an problem on the power supply, most likely one or more other capacitor that are bad but can only be verfied with a capacitor checker. They may not show any signs of damage or bulging but still internally damaged.
-may be more time savings to just replace the entire power supply

Acer monitors bad caps


Your not using the correct ratings on the replacement caps. The replacements neewd to be low ESR, high ripple current and high temp because the switching power supplies put a lot of stress on the power supply parts. The Acer units just stress the caps a little faster than other models. Any other brands that you have repaired with these parts that are not to spec will fail within a few months and could damage the power supply board when they do. Here is a link to more information about getting the correct capacitors for monitor power supply repairs.

The link article shows brands and series that have the correct rating for this use.

Help new power supply will not power up.


if you had a surge, it could have damaged more than just the power supply. When you plug in the unit, does the power indicator light up??? your main board could also have damage. The main board sends a signal to wake up the power supply thus turning on the TV. If you have to replace the main board as well, it probably won' t be economical to repair the set.

LG 42PJ350 tv, will not power up, just clicks


Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

What capacitor do i need to replace the old ones in DMR-E85R to fix the problem with "please wait"


Best bet is to replace all of the electrolytic capacitors in the power supply one by one, noting original capacitance values, and voltages (capacitance values are marked in µF as well as their voltage on their jackets), uprating the value/voltage where necessary, and observing polarity (the negative pole is marked by a stripe down one side of the cap, and replacements should have this opposite the + symbol on the board) when fitting new ones in the PSU.

It may also require replacement of IC1, a 12V 5 pin IC regulator, since this may have been partially damaged by the increased output voltage of the failing electrolytic caps in close proximity to it. This device has its type number (prefixed by STR) on its face, and should be available from Panasonic. Make sure if you order a replacement, that it is for THIS MODEL only, and that it is for the power supply in this unit.

Before you go out and buy a whole bunch of new electrolytic capacitors (available from most electronics stores including Radio Shack etc), take a visual look at the power supply (unplug unit from power point, and carefully remove the power board.) Examine it carefully, and note each capacitor that you can the value/voltage of - write it down, and obtain the closest replacements of each. Don't panic if you can't get a 20V 680µF, use a 25V 1000µF instead.

The total cost depends on how many electrolytic capacitors require replacing, but it is best to replace ALL of them one by one, to ensure reliability of the circuit they are in, in this case, the power supply. Don't worry about the IC regulator or any other parts just yet, do the caps first, as these are not terribly expensive, before taking any further action.

I purchased an rca rlc1906 19" tv 2 months ago, worked fine when i turned it off last night, when i got home from work tonight i tried turning it on. but all i had was good volume but had no picture,...


Same RCA RLC1906 LCD T.V.
"Same problem"; working normal shutoff, and never came on again; just white screen.Took off back cover to inspect "CAPS"... all looks good.
To this point only thing that seems odd is resistance varies 50ohms between diods D5, D6, D7 on main power supply. On another note
our tv was supposedly a refurb yet considering that fact; I closely inspected all three circuit boards, and none show any signs of repair, meaning everything appears new, original. If the capacitors are blown it should be pretty obvious by swelling or leakage. I don't see any of those obvious signs of heat damage. Diode's don't appear shorted when reversing polarity but D6 specifcally tests just over 600 ohms, all others test just over 550 ohms though I believe they are all suppose to be identical value. Perhaps that helps but I am going to try replacing diodes first and retry as it does seems power supply is also connected to video input/output which I would think is inverter board!

Power Supply Buzz


Did you use the same as original replacement capacitors? I have repaired many of these power supplies for others and never had an issue. It is possible that the failing capacitors could have caused more damage to the power supply but I have never seen it in over 50 repaired AKAI power supplies. Also, make sure you replaced the capacitors with the proper polarity.

Mobo no boot after changed power supply


I couldn?t find much on the motherboard either. Over the years I have only seen a handful of boards with fuses so I doubt you have on your board. -Double check the new power supply and ensure it is designed for your motherboard. -Double check the power supply connections to the motherboard, the connectors should mate up exactly to the motherboard. -If you did remove anything double check for shorts, grounding and so on. Any of those can cause the same symptoms. -Test the case power switch, it could be bad. -Some power supplies have on/off rocker switches on them (in the rear by the A/C power socket), make sure it?s on. -Most power supplies have a 115/225 volt switch in the rear by the A/C power socket; make sure it is set to whatever is appropriate for your country. I assume you use 115V like we do down here. -Make sure the A/C power cord is working. -Test the power supply in another computer or if not available you can generally pickup an inexpensive tester for $10 to $15 at a computer store that sells parts. -If you get this far and still have no solution then my guess would be the old power supply had a power surge on its way out and damaged something major on the motherboard. You can look on the motherboard for obvious signs of damage; however, unless you know what you are doing I don?t recommend the typical user try to perform repairs of this sort. Let us know how things go or if we can help further.
