The power supply is failing, or there is another circuit area that is pulling too much current, and the supply is going in to protect mode.

This would require proper troubleshooting by an experienced tech. If the problem is very involved, or the tech is not familiar with the set, he will require the service manuals and service information.

SOURCE: I have a ViewSonic N3250W Television with

Does the LED kick on when you push the power button or when you apply power? Typically, the 5volts will run the microprocessor and that looks for a command (power button). When it sees a command, it will send a signal to the power supply to kick that on.. so at this point, you want to look for that signal. If you push power and no power on (p_on) signal goes to the supply, its likely your main board.. but if it does, and the supply doesn't react, then maybe its the power supply. I am not totally familiar with this tv, but thats how all of them really work. Even if the caps look good, some could be bad.. look for brands like "capXon, sanXon" are typically the defective ones, theres another but its slipping my mind.. usually 1000uf @ 16v are bad, or 2200uf @ 10v are also common.. you can search the value and the little code, usually like C9M or something and see if that batch has known issues..
let me know what you find, or how I can help

I am working on the same power supply right now, my has a bunch of bad caps that I already replaced but I did not try to turn it on yet becuase I see that RS1 and RS8 are missing, some one had try to fix this power supply. Can you please tell me the value of these two resistors? Please see my pictures at http://s807.photobucket.com/home/budm/allalbums
Your problem sound like the logic board problem, I can tell you what you should have if I can find out if these two resistors were left out from the factory or some had removed them. I fixed the same power supply for the N2652 but I did not take the pictures of the board, I wish I did.3a99fcd.jpg

Why is the green led blinking on my M3N72-D motherboard


The flickering green LED on the motherboard is illuminated by the standby power supply, a small completely independent, always on, 5 volt power supply labeled 5VSB usually, output is on the violet wire.

Here's some more detailed instructions about how to check a PSU.

Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

Thomson DT!6300-16 has stopped working


Usually to fix most odd problems on the Thomson digi box you should do a hard disk format every couple of months, select menu, setup, help,
press green button on remote
this shows advanced menu, press blue button, warning should show,
press green button to proceed
takes about 2mins you lose all recorded programs

If the problem is the box stays at red, and won't switch on,
pull the mains plug wait a few secs then push and hold the the standby
button on the main box (not remote) then insert mains plug, as soon as the
red light flashes release the standby button and very quickly press
menu and OK in that order, don't hang about, it has to be done very quickly
I had to do it several times before I got it right, this loads a preloaded firmware
and the box will come alive again the box will upload new firmware in a couple of hours.

good luck from Ron.........
