How do I stop the light flashing

there is a possibility that the power switch capacitor has bubbled or leaked a remedy is to unplug the unit from the outlet for at least an hour then try to power it back on.

i will try to look for more information about other work-around's or which of the other parts are defective or almost defective, that is causing the problem.

Is the tv new or has it started to do this recently ?
Try to eliminate the obvious.
Does the remote continue to flash when you release all of the buttons? Is it a stuck button ?

If you cant' see the remote output, try using your smartphone camera. Most phone cameras will capture infrared light ( invisible to the eye). Aim the remote at the camera and see if you can see the flashing light, which is data being sent to the tv. When you release the buttons does the flashing stop ? If so remote is ok

Next turn all of the lights off in the room with the tv. Also turn off any lights that may shine in from other rooms. Try using the remote

If your tv functions normally, you may be getting interference from your lighting. Some LED and CFC fluorescent lights flicker at a rate which may be close to the remote IR output frequency.

If turning off the lights fixes the issue, turn on each light to isolate the issue. Replace the bulbs with ones from different manufacturers.

Unable to Power On or Off the set

Symptoms / Customer Description
The symptom may occur while the TV is ON or in Standby.

1) If the problem occurs while the TV is in Standby:
The TV will not turn on via the remote or power button located on the set however after AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

2) If the problem occurs while the TV is in use:
You may lose the ability to power off the TV or switch the video inputs however channel changing, adjusting volume, or accessing the menu may still be possible. After AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

Sony has designed the BRAVIA Televisions to be CUSTOMER Software Upgradeable and therefore Sony will not pay a service claim on any issue resolved by a software upgrade. If a customer requests an update please refer them to the following website: http://www.updatemytv.com. If the unit requires the update, you may enter the customer's information in the website and a USB device will be sent to their address.
If a customer does not have access to the web please have them call the Sony Call Center Support line: 1-866-210-6333

If a customer reports either symptom above request that they unplug the set from the AC wall outlet for at least 30 seconds and then plug the set back in. This will reset the TV and it should work fine for several months. If resetting the TV does not resolve the issue the customer has a different problem and a service call by a technician may be required

Similar problem. Unplugged for 36 hours and it works

Hi,
Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
Thanks.

if the lamp light is flashing,remove the lamp and check it there is 98% of possibility that is bad.

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.........

Sony FD Trinition Wega KV-32HS510 Try to turn tv on -it starts then shuts off -stand by lights keeps flashing. Memory stick light flashes then goes off.

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Reverts to standby from switch on via TV or Video
No 5v rail because FET MTP3055 o/c. (BUZ71 will do nicely)
Goes straight to standby, after a quick burst of power
Replaced R952 (39K), had gone slightly high
