This is usually due to the power supply going in to the protect mode, and failures in the scan amplifier and or the CRT drive sections. It is not a simple repair.

Good afternoon, Sirs! I bought an LCD TV Sony KLV-32S200A four years ago. Yesterday the TV didn't turn on. The standby light blinks 5 times and pauses for 2-3 seconds, then blinks 5 times again. Could you...


Hello
Blinking of standby light is Sony TVs are fault indication. Five blinks denotes

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. You must have some knoledge in electronics and ability to follow the schematic diagram of TV otherwise called as circuit. Must have a high quality digital multimeter, soldering iron and a concept of soldering. I'll assist you. Must have confidence and more patience. If you have these, inform me by Fixya. I'm happy to assist you. If not, get it repaired by Sony Authorised service center. Any service center, who takes this set for repair, must have all the testing equipemets like oscilloscopes, clour analiser, pattern generator and AVO meter. Without these testing equpments, trying to repair this set will make things mor worse. OK.

Sony Bravia 46" The standby light flashes four


Hi,
If tv model number is KDL-46S2000 then 4 times blinking standby light indicates back light failure problem in your tv.
Check/ replace back light inverter boards to solve its problem.
Thanks.

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.

My tv shut off by itself & the standby lights flashes 4x in red


The four blink pattern indicates inverter failure. Since there are different inverter boards for this model (depending on the serial number), I recommend that you take your TV to an authorized Sony servicer for repair.

T.v on standby, red light flashing 3 times, wont switch on


Shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.

Standby light stays on


When attempting to turn on the set, the standby light should blink for a a while then stop once the picture comes on. If a problem is detected internally, the standby light should blink in a repeated pattern. Please count the number of blinks that are repeating and we should be able to help.

Thanks,

Four blinks = No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

The standby light should be blinking in a regular pattern. Please count the blinks and report that number here. It is an indication of the problem circuit.
