Bad capacitors on main board

We are obviously on the same wavelenght. I did exactly that, replace 3 capacitors. However, I now suspect that it is the Inverter Slave Unit. This powers up the backlight, enabling light to the panel. Otherwise, I will simply replace the power supply unit. THANX 4 your advice.

Yep, i also realized that it was lead free solder as well (big difference than regular solder.) im going after the inverter 1st hope it solves my problem thanx 4 everything.

That is great news I really like to hear when people work on their own repairs, did you make sure the capacitors were soldered in correctly? there is a negative and a positive side if one is reversed they will not function, I have had experience when the caps are not the culprit the transformer legs usually have a bad output, and given a good transformer high output then the Chip is bad. I have found replacement main boards on Ebay there are several shops selling good guaranteed parts, I repaired my own Emerson's with a replacement board from a provider on Ebay, for 50 dollars. you should be able to check output on a power supply unit when plugged in.

Have a Samsung 37" tv that turns on fine for a bit then transitions into green shadows and lightened blacks after a couple of minutes (all inputs).

The T=con board is the culprit.The power supply will fail sometime in the future. If you can, replace the bulging caps . Replacing them all is best since they all are the same age.

1- Crumbs or part wearout may be keeping the plastic latch from engaging. If you have the toaster apart, you can compare the arm latching action of the good side with the bad side--maybe there is an obvious difference in the travel of the arm that keep it from engaging.---leaving the travel short even 1/8" can keep the latch from engaging.

2- If there is nothing obviously mechanically wrong, then it may be a control board malfunction. Make sure the 3-pin control board connector is plugged into the transformer/solenoid board. Since you are getting lights, this should be OK. You have at least one good board (the side that works) so you could plug that board into the other side to see if the arm stays down. For fun, you can plug the bad board into the other side to see if the other side now malfunctions. If the problem follows the board, then you have your answer.

If you know someone that understands electronics, they may be able to repair the board--have them look at electrolytic capacitor C1 and make sure it is good. If that part is bad, it can be replaced for about $1 by going to Fry's and purchasing a replacement capacitor. After a couple of years of use, a defective C1 may "dry out" and cause control board problems.

  • I repaired the same symtom that happened to one of the sides of my CPT-180 toaster. The magnets wouldn't engage due to a bad C1 capacitor on the circuit board that controlled that side of the toaster--the capacitor was bulged out on the bottom and turned out to be bad. I've attached some photos showing C1 bulged out compared to C1 on the good board.
    C1 is the main power supply capacitor and if it goes bad, the circuit board power supply won't function correctly. This can lead to a broad spectrum of problems like the lever not staying down due to the magnets not engaging or the toasting control/timing circuits malfunctioning. If you replace the capacitor, it is best in most cases to replace with the same value as the orginal (220uf on my toaster)---you can usually get a replacement capacitor at Fry's Electronics. Replacing with a higher capacitance may be acceptable, but you should understand the impact to the rest of the circuit before you substitute a higher capacitance value. The voltage rating and temperature rating of the replacement capacitor should be the same or greater or the capacitor will fail quickly. Note the max temperature rating of capacitor C1 is +105C---toasters get hot (duh!) and the temperature around the circuit board of this model gets quite warm, so the temperature rating of the capacitor is critical. Finally, make sure the substitute capacitor fits when installed (requires soldering) and does not interfere with surrounding circuitry or other toaster mechanics when the circuit board is put back in place.

Samsung LCD TV Model LN46A550P3FXZA sound is cutting in & out 1-2 second intervals

Your video and audio (sound) signals are generated on the main board. However, for those circuits to work properly, they have to have clean and accurate power from the power supply board. The power supply boards are notorious for bad capacitors. Has your power supply been recapped? Do you see any bulging tops of any of the capacitors? If you are not familiar with capacitors, just google bulging capacitors. There are plenty of pictures on the web to show you what they look like. It is possible that the main you have has a problem. I assume you order the same exact part #?

32" emerson tv

I would suspect the power supply first Most likely bad capacitors. The main board would be suspect next as the power on command comes from the main board which switches on the run supplies.

Lc 70le633u light flash can not power up

Does it have a standby light? If standby light is visible main fuse is likely ok, Suspect bad power supply check capacitors for swelling on the power board, if not, suspect main board.

I am sure that the fault was relative of the bad capacitor and swapping the working board has proved. Hope that solves the issue as all what is needed is to check and replace all the suspected capacitor is the Primary /Secondary side as the SMPS is working BUT with a limited voltage. So the threshold is low and so can be a tank capacitor, change the mains capacitor and also the secondary +B side.

I have a panasonic TC-P42C1 blinks 10 times no picture no sound What is common to go on this model (which board)?

Check the tv power supply board.That the board where the tv power A/c plug into it.Check the tv power supply board carefully for dying components parts that are called capacitors parts.Bad or dying capacitors parts on the tv power supply board are alway causes this problems to the tv.Bad or dying capacitors parts are very easily to spots,all these capacitors parts are alway bulges up onto it tops.Never have plats round tops as they suppose too.U have all the tools and know basic electronic also can do basic soldering work,u should changes all these dying capacitors parts in the tv power supply board with no problems at all.If u check all over the tv power supply board and it have no dying and leaking capacitors parts to the tv power supply board all.Then the tv Y-Sustain main logic Tuner board it is the causes and the problems.The tv Y-Sustain main logic Tuner signal board that is the board that take in the tv imcomming tv broadcasting signal cable plug into it.Or tries websites like, to buy a whole new refurbish tv power supply board and or the tv Y-Sustain main logic Tuner signal board for the replacement.

RCA DRC257N No Power

Had the same exact issue. RCA DRC257N was acting funny, frequently freezing up at HELLO screen, sometimes buttons would stop working during playback, requiring frequent unplugging to get back to working. Opened the case, pulled out the power board and noticed that capacitor C411 (1000uF 16V) was bulging out at top and bottom. Replaced with a $1.59 1000uF 35V capacitor from Radio Shack and all is back to good working order. Thanks.
