Set has power, but fails to turn on

Set has power, but will not power up. Power LED flashes repeatedly. I was told that the problem was the power supply from the person who gave it to me. I tried searching for a replacement PB, but they are no longer available.

Your going to need a schematic diagram and some troubleshooting skills here or a quilifyed repair person. This set has several power supply problems as well as sweep dirived power problems. The biggest problem is the STR (I dont remember the other #'s)(ie- STR#####) regulator IC It is alway the first thing that goes bad in these chassis. Now do not get a general replacement as it will blow out as soon as you turn on the set. I've been through this and a half a dozen regulators till I relized that the replacement ics do not have one last digit on the ic that the original did have!! and that one last digit made the ic completely differant. Another common problem here would be The Two filter capacitors off the sweep derived 15 or 18 volt lines Good luck to ya.

I have a 62" rca led hdtv.. when I push the power

How many times does the light flash each time? Also whats the full model number of your set?

Ga-x58a-ud3r the pwr led keeps flashing but not always depending on what im doing (pwr led front panel). this is a new system. i7 930, 12gb corsair xms 3, four 500 g hd raid 0, geforce gtx+ 9800 512mb,...

that is custom system like mine a DIY build
and custom unstated case., bought as new case only I bet of vast.
and if built wrong it fails.
the LED is where the POWER on LED wired wrong is it.
the Power on led does flash wired correctly for sleep mode.
if wired wrong is now the HDD activity LED, and should flash
x58 is good chip set, pure intel it is
usb3 chip NEC needs good driver so watch out there.
pwr_on LED
goes to pins 2 and 4 only on the header. page 30 in linked manual
if is wired correctly the led is called MSG

MSG/PWR (Message/Power/Sleep LED, Yellow/Purple):
Connects to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-On is in S1 sleep state. The LED is off when the system is in S3/S4 sleep Blinking state or powered off (S5)
so the manual told you blinking is S1 power state ACPI.
other causes
bad LED (power button)
loose wires at mobo end of that or at power switch.
mobo bad, here, rare as hens teeth if user did not jumper DC power to this LED pin and blow the driver transistor up. guesses wild does that.
BIOS controls (you set it) soft power off , instant off or off. mode.

no case told some are dead wrong here, some cases , use a 2 way LED for power, and is 2 LED wired in parallel and reversed
to get 2 colors . and fails on simple mobo. not using bipolar controls to LED. NO CASE told so NO JOY , 10,000 cases made or more that the same but generic cases do work if is that, not OEM cases..

I have a pioneer pdp4340 the standby light flashes 3 times then repeats over and over after you power up . then it shuts down . i was told it was the x card . by a pioneer thec where is this card located...

Tv is going into fault protection mode at startup. When set turns on relay clicks then turns off with NO OSD-On screen Display and a blinking fault LED. This in indicitive of blown UF capacitors on the PSB-Power Supply Board. On an opened set the PSB is located in the center. You want to look for 2 or more UF Caps on the PSB. A bad Cap will be completely poped or bulding at the top (X) which shold be flat. THe X-main Board is to your right the YSUS Main is to your left

I have a 2006 Sony Wega 50 inch. set turns off after 10 minutes, green led flashes for 45 seconds and then set turns on. it repeats. is the power cord bad?

try to powercycle to reboot, check connections if tightly connected. advise cable provider (if any) to send signal to refresh if have cable box

Red power light flashing; will not turn on.

It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.

Another problem with my 52725

It may very well be a connection issue with one of the wire connections as its not giving you a error code. I would double check the wire plug connections

Samsung SlimFit TV made a pop sound while watching it and turned off on its own. Will not turn back on. The power light flashes five times and pauses. I was told maybe the vacuum tube?

A part most likely failed in the power supply or some other board. The flashing light is indicating that the set is in the protect mode.

It is possible that the failed part caused some other damage. You will have to send the set out for sercice.
