Same problem as rrobert4

Rrobert4

I am having the same problem and, also going to change the 1000UF caps. Did replacing the caps fix the issue? If that doesn't work I am just going to order the whole board but it's tricky cause I dont know if it's just the board or if there is another problem that caused this board to fail.

    So what do you suggest I do if I change the caps and it still doesn't work. There are about 4 leds on the main board when I turn on the tv 3 green light up after two seconds the relays click and then the green leds turn off and a red one turns on. Do you know what the red led is tring to indicate specifically, other then there is something wrong. Emial: leguwan@yahoo.com

The power supplies in modern TV sets are absolutely miserable and probably half of all problems stem from power supply malfunctions, not caused by circuits beyond them.
BTW, the main filter caps that you are replacing don't fail that often. Mostly it is lower value, lower voltage caps in the supplies feedback path that keeps the supply regulated and running are at fault.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
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 issue) on youtube.

When the menu starts rolling, take the remote out of the room to see if it's the remote causing the problem.

if it's not, check for bad capacitors on the boards.

If you repeatedly turn it 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 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

Not turning on at all


check your power supply. remove it then remove the metal plates on top of the psu. ill bet you find 2x 1000uf 35V ,4 x 1000uf 10V and 3x 670uf 35V capacitors that are swollen or leaking. if you replace the 1000uf caps it will work but if the 670uf caps are swollen as well its a good idea to replace them as well. the 1000uf capacitors can be bought at radio shack for around 10 dollars. you can use the 1000uf 35V caps for the 1000uf 10V caps if you cant find the 10V ones . the 35V caps are a little bit bigger but still work . you will need a good soldering iron (35-60 watts) and a good desoldering tool . easy to do if you know how to solder.

This is a power board going to the lamp of the DLP MITSUBISHI TV I HAVE THE NEW LAMP BUT THERE NO POWER GOING TO THE LAMP THE TV HAS POWER IT WON'T LIT THE SCREEN


there are bad capacitors on the power supply.
look for bulged caps

they look like this
replace the big ones on the power supply to fix the lamp issue
there are more bad ones inside typically on the dm and fmt boards
they are 1000uf - replace those ones with 680uf @ 16v caps

let me know if i can be of further assistance

RE: Replace 16v 1000uf


You can change the voltage rating to a higher one without compromizing the circuit. You can not lower the value however. In other words, using a 1000uF cap rated at 16V would be OK. The short answer is no, you can not use the extra caps you have unless you put 3 of them in series. (I doubt you have the space for that.)

Hi, I was able to fix my set by changing only three out of the six capacitors between the heat sinks opposite the plug on the board. I noticed under a microscope the caps looked a little puffy, but not much, and I checked them with a capacitance meter, but they were in tolerance, but decided to change the three closes to the edge of the board with a 1000uf, 50v, 1000uf 25v and 1000uf, 50v with the one that is 25v going in the middle, I didn't have another 1000uf,50v for the middle one. (sometimes you gotta use what you got to get what you want) So I powered my set up and it stays on . I hope this helps. I may go back and replace all six with 1000uf, 50v, but the space in there is limited and those are some large caps. I will wait until the set acts up again before i do that. I am satisfied with it for now. Again I hope this will help with what you've got going on with yours.10_25_2011_8_27_53_pm.jpg

Problem with starting


read on a forum that changing out c316 1000uF will fix the problem, mine will not turn on now, seems to have gotten worse over time. I will change the capacitor from 1000uF 10v to 1000uF 16v.  Look at your capacitor, mine looks like its ready to blow.  Most other capacitors on the board are rated at 16 volts.  I will be changing out the cap. to see if it works.
