Check if the 4-pin connector from the power supply is connected. Remove the RAM/memory and turn on the computer which should create a beeping sound an indication that there is no RAM/memory. Turn off the computer and remove it from the outlet. Put the RAM/memory back and make sure its properly seated. Put everything back including the power cable to the outlet, Power On the computer. That should do it. However, if the same thing happens, it can be your motherboard or your RAM/memory that is faulty but if you have several RAM/Memory or an extra, try to put it one at a time in order to identify if one of those is defective. Please let me know if you find this helpful, thank you and regards.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Vizio E320VL has yellow light but wont turn on even with a new Power Supply


The power supply get's it "turn on" signal from the main board. It is very likely you have a faulty main board. Do you have electronics experience??

My VP504fhdtv10a vizio plasma TV when connect power cord the Vizio in front light up yellow/amber but will not turn on. I have replace Logic Control D Board still have same problem. I do research online...


Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

Turn itself off as soon as you turn it on (37MF33ID/37)


in the lcd tv there are three main parts
1)the inverter board(pannel)
2)the main board .
3)the power supply board.
----------
if there is no power at all them main board is faulty.if no front led light is coming ON there is no power .so the main board is faulty.on the main board there is a fuse located you have to replace that and check first if still no power main board needs to be checked and replaced
---------------
if there is sound but no picture and front led light is ON then its inverter board panel problem.if this is your case replace inverter panel.its located in the lower side of the lcd in the inner area below the main board.
-----------
but if there is just front led light blinking , but no picture or sound then its power supply board problem.
------
but as you mentioned that the tv turns ON for some seconds then automatically turns off this indicates that the power supply board is not faulty but there is a component on the board that is getting over heated because its got weak so due this overheating of a component the circuit gets short and tv shuts off.
on power supply board there are some capacitors and ic located.if any of the component gets short or budged up then it short the power supply board.so you can check the components on power supply board with multimeter and get it replaced by using soldering iron.
----------
also you can get new replaCEment power supply board.this clears the problem completely.
---------
you can get the required board and components at ----- www.partstore.com -------- or from ------ www.radioshack.com ----
---------
if you are not familiar with doing this you can get it done by local tv repair technician familiar with this model tv.
-----------
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

3 red lights and yellow power supply light


at the very least the main board is acting flaky with the 3 red lights flashing. Here is tutorial courtesy of LLAMA to show how to resolve that problem:

http://www.llamma.com/xbox360/repair/ring_of_light_x-clamp_fix.htm

As far as the yellow light on the power supply is concerned. Unhook it from the Xbox 360 and only plug it into a power outlet. If the light is yellow then the power supply is bad. If the light stays green then plug it into the xbox 360, if it tells yellow then, at that point you know that the main board is causing the yellow light on the power supply and that means the main board is bad.

LG Washer wont start, no power


Make sure there's power getting to the washer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the washer, if this is the case, the wiring must be repaired or replaced.

Power Problem


usually blink code on front gives direction but first thing to do would be to determine if surrounding sustain boards are causing draw on power supply by disconnecting them one at a time from power supply. y is on left looking from back and x is on right looking from back. if led goes solid with either board disconnected check supply voltages and if come up and stay up replace that board. if no change then you would need to verify vs on command coming from logic main to power supply. should be labeled on power supply connector and should be 3 volts. if present replace power supply if not present verify if logic main board sitting underneath signal board has one solid and one blinking led on if verifying normal operation and if so replace small signal board
