The TV won't turn on, and the standby light is blinking in groups of 5. The manual mentions this, but only that the number of blinks is significant, not in which way. What do we do?

These blinks to standby light are fault indications, called blinking codes. From the number of blinks occur at one time switch on, you can get an idea about the faulty circuit stage inside it. Count it. Visit this site. It has details about blinking codes to many brand televisions.http://electronicshelponline.blogspot.com/Pull up older posts there, either by its left side bar, or see it in Timslide option

The inserted video have no details about the brand name of the TV. Anyway, understand that these blinking are fault indications. Count the number of blinks occur at one time switch on. If you wish to get more details about the blinking codes, check this link. Form the number of blinks, you can get an idea about which section circuit is faulty, and will make troubleshooting more narrower. Check the above linked site patiently. Blinking codes and troubleshooting procedure to many brand TVs are given.

How many times do this standby light flashes at one time switch ON? Count this and make sure, how many times it blinks. These blinks are fault indications. From these number of blinks, you will get an idea about the faulty section circuit inside it. It will narrow down the troubleshooting. If you wish to get more details about Sony Blinking Codes; check this link.

Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.

On Sony the standby or red is for shutdown---

If you unplug the set and plug it back and turn it on and it repeats this look to see if the light is either constantly blinking or blinking a specific number of blinks---specific number would be an error code.

Usually Sony and LG Blinking Codes are the same. Here is what I have.

• Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  
• Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  
• One blink - not used for the self-diagnosis
  
• Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  
• 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,
• Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  
• Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
  
• Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
  
• Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  

• Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.

• Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).

• Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Hi


Thanks for using FixYa. Standby/Timer light blinking 6 Times means no Horizontal (H STOP), no raster, and so the set goes to the blinking self-diagnosis function immediately. You’ll need to open the back off the TV and check C515 & 516 and the jungle IC, IC206. Also check +5 line is overloaded (A, B boards), +5 line is shorted (A, B boards). Please do rate the solution if the issue is resolved or post a comment for further assistance.



Thanks

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.

Replace This Diode: D647 ( Sony part number 6-500-567-01 ). Go to: http://www.encompassparts.com/tritronics// For parts. I will be here for future questions. Thank you
