Toshiba 27wlt56b dead psu

Apply new turmal compound to your cpu and try to start again

so no English?, OK I'll nibble the hook...
so I google translated it for you like this: I added punc.
"My pc is down.
fan and hard drive turn around, but nothing on the screen.I would like to know if it is the motherboard or the processor: 1333 Acer Q45T-AM V: 1.1 15-V59-011100 DDR3"
----------------------------answer------------------------------------------------
if the processor is on the Acer.com qualified processor list then the processor is good, with heat sink and fan, never missing.

first of all the actual PC is not stated, you post only a RAW motherboard and then not show a photo of it in use.
so answers are hard won, and log... if at all.
no monitor stated, no PSU stated, no cables types stated,
VGA? DVI., HDMI> ? on board video jack or PCI video card?

so is it CPU bad/wrong or fan dead?
is it mobo bad
is it monitor gbad
is it DDR stick bad.
is it VGA port dead on mobo or cable.
is it PSU dead.
6 possible things not 2.

one more the power pin must be jumped, for 7 things wrong.
8 possible if using VGA card.
there is no PSU aux jack so no newer v2.2 PSU needed.

ok, a simple hardware question only. w10 could careless about PSU. (facts) mobo is micro atx size 24.4cm x 24.4cm
not powering up has many causes, even simply stuck in sleep mode. (power on button held for 10seonds and released last is 1 cure. of about 20 causes (up to)
GA-F2A78M-D3H (rev. 3.0)or rev. 4.0????? rev is on bottom left of mobo, normal tower case. no case told
the PSU is called ATX and all work here 500 to 750watts
24 pin power is normal
but CPU power uses 8 pin power plug PSU.marked ATX12v
psu lacking 8 pin, can use 4 to 8 adpater.
vast here work, in real ATX case not micro cases.

from you manual .


dead PC
are all fans dead.> that is dead PC.
the monitor must be good and connected the the VGA jack
if using GPU card then it must connect to the monitor
the BIOS screen must work or the PC is dead or GPU card is dead.
strip the PC down ,any thing in the PC shorted will make PC dead.
if strip down tests fail the PSU may be bad is its fan dead too?
both power connectors most be connected above or PC will be dead.

It only says "no signal" on the screen, when it does not get a signal. So check you did plug in the correct cable from your antenna or receiver. Also check the cable for bad contacts. Do check an antenna amplifier if it gets the power it needs (when used)

I am answers for Monitor /PC mobo dead. only ,not windoz ever, and Linux works best here. fact.
I see you lost the beeper device (SOLVED ) !!!
Not putting in a new RTC CMOS COIN cell battery first, is bad. ($1 fix)
A bad coin cell make BIOS Dead or BIOS tells all lies endlessly. the cure is $1

well no history told at all , 11 years old and coin cell dead. I bet.
bought a bad 11 year PC that or just failed 11 years in use,
bought it dead, or failed just out of the blue, not TOLD
no history of PC told. at all.

the mobo some versions of 7, beep and others flash led codes.
dead PC , monitor tests good.(evidence)
no signal means video port dead or set to the wrong port on the monitor,do not trust auto mode set it manually in OSD. ok
is this a VGA cable , no bent pins?
Does the PC have PCIe video card , if yes remove it and use the case mounted vga port blue on mobo rear edge.

Dead signs on relic VISTA PC.2007MOBO.
FIRST OFF BIOS DOES NOT MAKE SOUNDS TO ANY SPEAKER PORTS. EVER. (WINDOWS DOES)
YES THE POST BIOS BEEPER CAN MAKE BEEPS ON ANY AND ALL P.0.S.T ERRORS.
NO PHOTOS YOU PC AT ALL, REAR NOR INSIDE WITH LEFT LID OFF,(so they helper is blind.
next you never said the monitor is VGA, sorry we can not guess that.
Not told at all if monitor was connected to the chassis (vga port or the VGA video car.s

no fans.????? (pcu FAN DEAD, ,CPU FAN DEAD, OR CASE FANS DEAD, AND IF GPU CAD, GPU FAN DEA.
NO CLUES THERE TOLD AT ALL AND CPU/PSU FAN MUST NOT BE DEAD.
forget EXT speakers, unplug that. until , monitor works now and windows runs, (or linux, etc)

no beeps, hdd heard (ear)
no bioSTAR splash screen means pre POST is Dead and bios is dead. and VGA port is dead.
bad PSU or PSU overloaded it seems to based on limited evidence.

no lights so that means power button led is dead
a new coin cell battery is first
bios hot key is? num-lock key OFF !!!!!
F2/ DEL:? is reset bios to defaults (im reading your manual to you NOW) if you can get a splash screen . and post to finish.

the monitor must be good and no-signal tells me that texted to screen. so monitor is good.
the most sad part of all no photos posted of rear of mean, So I can see things connected wrong (sad :(
The VGA port is dead and PSU is dead too.
why is the question
CPU socket has bent pins, seen used mobo on ebay lots. Core 2 Quad / Core 2 Duo / Pentium D / Celeron
1:coin cell dead. sure it is. (next to CPU)in a vertical socket,.
2: PSU not bad (caps inside a wreck, bad) 4 pin and 24pin DC power plug to mobo , now.
3: PSU overloaded, strip down the PC. to find what is shorted
4 : MOBO jumpers missing or inserted INCORRECTLY per the MOBO manual , words. JCMOS1?

DO not flash bios on any sick PC or you brick it, (oops buy it dead like this OOPS)
testing first
monitor VGA cable to VGA port rear of mobo, mounted to MOBO called the onboard VGA port.
no PCI cards NOW
no usb devices (keyboard added if BIOS wakes up) use rear USB for keyboard only (for now)
no hdd or dvd drives connected. not yet.
1 stick of DDR ram tested 1 by 1.
no video cards. now. (just to be clear I repeat this ok/)
If the PSU is not bad , now, and monitor still dead, the MOBO is bad
PSU 24 pin and 4 pin power must be connected to the mobo now. the 4 pin us just above the VGA jack,
if all is still dead. unplug the PC (PSU) from wall AC power overnight or more
IN the morning or later try again. (PCs can in fact latch up, and this AC power trick , can wake it up
and now the BIOS SPLASH screen shows and F2 BIOS hot key and all BIOS pages work,, now.

Warning , never hot plug any parts inside the PC with AC cord connected to AC WALL power.
that is called Hot swapping will blow parts up, for sure DDR. memory for sure power DC cables hot swapped (boom)
do not do that and not wreck good electronics

Hint1, the keyboard LED dead mens lost of 5vdc , from the PSU., (USB ) if using USB keyboard , not told that. P/S2?

Hint2: some version of these mobo (many) have no onboard BEEPer device (sonic) not sure how it does POST errors, but the book says,(free) some have beeper device and the manual shows AMI beep codes page 25
v6.5 is not easy to find docs.
also some BIOS here use he DEL key (not F2) to gain BIOS pages. at power on. (keyboard USB only)
the caps lock key must not be set wrong or DEL key will be dead (DEL/dot) dot mode fails on some.

this PC was built in The Cap plague year 2007, so was PSU? and they all leaked acid or bulged.

to bench test a PSU ask, (using just a paper clip unbent) ASK

oddities, on this mobo, wow, losts but this one takes the cake

JUSBV1: Power Source Header for USB Ports

step 2 the TECH uses a voltmeter and checks all wires on PSU for correct voltage.

PSU in Desktop dead, my guess fans dead too right>
you never said, what it does inside PC ,except nothing
does nothing mean dead silence?
the fan must run for 1second, then goes off.
a 1 second run tells me the PC power switch told the MOBO to turn on and in turn it tells the PSU to turn on,
the PSU then turns on for at least 1second,and if the voltages are ok
then the PSU stays on, else off goes.

15 and 16?
the 20 pin older supplies those are both ground
but 24 pin ATX pins are correct there.
the voltages are here.
https://en.wikipedia.org/wiki/ATX


There are 2 causes, of dead power button.
1: the buttons 2 wire cable ends fell off. at button or PC mobo.
2: The PSU is bad.
3: the MOBO is bad.

The mobo can also shut off any PSU, if the PSU fails
or it sees the regulators in the MOBO fail.
the Desktop runs on many power rails.
some in the PSU, others on the MOBO.
THe mobo creates special low voltage for the CPU.

the power good pin, does that #8,
One way to see if the MOBO is overload
is to remove things from it, I start at RAM
lacking a voltmeter, this is very hard to fix any thing electric.
only guessing or pulling objects PC can find shorts.
pull all power cables there, hdd, power, cdrom.
all things that use red/yellow wires.
all SATA cables, all USB , then ram. even a fan can short
a good tech keeps an open mind, and finds why the PSU shut down.
in most cases, the PSU is bad. but not always.

This is a feature, of ATX it keeps you from blowing up say a
$300 microprocessor.... or fancy gaming Video card (have one)?
yes, pull the video card too.

replace it. and you might want to replace the cap with one with a higher voltage, too. toshibas are known for their blown caps that are underrated.

there it is a complicated problem your tv seem to have one big problem with the supply module inside him the power current was accidentaly increased and now your tv dont respond better and your picture is enlarged because had a big alimentation current and now you must to go in authorized service to fix that problem
