Question about Televison & Video

1 Answer

I have an element TV with a MLT070A power supply board. I'm not an electrical guy, but a technician came out and showed me the bulged caps and said that was what's wrong with the TV. He said he couldn't get replacement parts (I think the whole circuit board)but maybe the bulged cap components could be replaced by someone. I don't want to junk this TV and wonder what I should/could do. They're going to send me a $350.00 check for the extended warranty I paid 650 for the TV and 150 for the Circuit City warranty less than four years ago. Is it easy to find someone who could replace these caps? Could I solder them myself?

Hello,

power supply board is dead, if you know basic electronics' and soldering you can handle it ? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.

Good luck in solving the problem.....

What part needs to replaced on Element TV?


I have three of these TVs in the shop. They are less than a year old. The signal board is good, the T-con board is good, and the power supply is good. The panel (once called picture tube) is bad. Much too costly for repair. Thanks for asking me.

Hi, my LCD Polaroid FLM-3701 went through a power outage and now doesn't get power any more. The power led doesn't show any light. I saw a capacitor repair kit available, and four 680 uF capac


The power supply fuse should be next the the ac input plug on the power supply. It should be a long cylinder type fuse, probably a T6.3AH/250V. You will want to replace those caps ASAP

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.

Regards.

When I turn on the tv the green indicator shows that it has power, but then it sounds a clip so it is not sound or display video


It sounds as if you have some bad caps on your Power Supply board. If you remove the access panel on the rear of the tv, you will see a couple of circuit boards. The power supply board part# usually starts with the prefix of PSB- ##########. If you look at the capacitors on this board you'll probably notice 4 of 'em showing bulging tops and/or leakage. get the part #'s off the board, go to badcaps.org
and order a replacement.Good Luck!!

Standby power no picture


The problem in general (as this question is) would be to inspect the power supply. The power supply board, in the TV will have bad capacitors. You will need an ESR meter to locate and replace bad capacitors. You may look for bulged or skinned caps, if you do not have an ESR meter. If you have an external power supply ( a black electrical box transformer, from ac wall outlet, with another cord that enters the TV) the problem is inside of this. Once again, you will need to replace caps here, thanks for asking and show all hands of support!

TV had no picture first and then no sound. I have unpugged TV and still nothing happens. There is a blinking red light on that can be seen from rear of TV ( 1 blink on and off). Thanks for your help.


Good day!

Please follow this procedure to fix your problem:
  1. Open the cover of your TV.Remove all screws at the back.
  2. Next,power ON the TV and check the output voltage of power supply using voltmeter.
  3. It should have not less than 5vdc for system board,12vdc for sounds and 24vdc for inverter board.If the 3 supplies are got a voltage drop your power supply had problem.For example if you check the 5vdc then the reading is 4.50vdc only.
  4. If you have voltage drop,check some leak/bulge on top capacitor on power supply.replace it using soldering iron and soldering pump.
  5. When the power supply looks like OK,no voltage drop and no leak/bulge on top capacitor.The problem is your system board or main board.There's no easy remedy for that.You have to replace the whole system board.
A Power supply is like this..(It is not actually look like yours but it was just for your Idea)

Screen goes on -then after a couple of seconds the tv cuts off


Hi,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.


I hope this will helpout.....

When tv is turned on the green light comes on and shuts off in 3seconds.


There's a good chance you have failing electrolytic capacitors, probably in the power section.
Any caps in this section (or any other section) that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same/similar issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

I have a T28PL1. I had a prolonged power cut and when the power came back the tv won't switch on, just shows the red standby light


Hello,

First, remote the TV's power cord from the wall, wait for about 5mins, plug it back in then try again. If problem persist, then it means your TV is having a power problem....
