Question about Sony BRAVIA KDL-52W4100 52 in. LCD HDTV

1 Answer

My Sony Bravia 52W4100 comes on for about 10 seconds, then on its own switches to the stand by mode. The picture and sound go off and the standby light flashes. It stays this way until I unplug it then the same problem repeats. No buttons on the TV or the remote have any effect. The TV is about 7 months old.

Test the power supply voltages after it shuts itself off, mainly the PSON voltage as that will determine if its a main board issue or power board

SOURCE: Flashing Standby Light (6 times every 2 second interval)

A 6 flash error indicates a problem with the backlight. Your set is less than a year old and still in warranty, so you should contact Sony and arrange for a service call to get it repaired.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

BRAVIA KDL-V32A12U PICTURE LOSS


THREE Blinks
B+ over voltage protection (OVP), unit goes to the standby
mode then displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
FIVE Blinks
AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.
