Have a sony bravia kdl-52v4100 and a red line keeps popping up on right side. it will show for a bit than go away but will come back again???

SOURCE: My Sony Bravia KDL-26S3000 won't turn on and is stuck in standby.

Hi,

There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.

Thanks

There is a error in TV.Count how many times blinking the red light.

• Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
  
• 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, check T603 and R672.
• Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  
• 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. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. 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. Check C515 & 516 and the jungle IC, IC206.
  
• 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 GA_googleFillSlot("TL-IMU-Article"); blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board. GA_googleCreateDomIframe('google_ads_div_TL-IMU-Article' ,'TL-IMU-Article');

• Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. 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" boards
  

Testimonial: "I also bought the Sony KDL-52xbr9 mine did the same thing with six blinks. I sent it back to to store. "

we have the same exact tv and it is not even a year old. we are told that it is the display panel and it is a well known problem with this tv. we were also told that there is a shortage of these parts. they had 283 on order, but only received 35. you need to call sony and tell them that you have this problem. they should warranty this for you even if your tv is 3 months past the warranty period. since this is a well known problem with this tv, keep on them.

Testimonial: "It in fact was a part of the lcd panel...the t-con board. I was able to research it and bought a box of parts off of a tv like mine and fixed it. Ron"

Power board have problems.Replaced capcitors puff up or burst open,Know how to solders?Or replaced the whole power board buy refurbish power board at Shopjimmy.com,Ebay.com.

I'm having the same problem. I have noticed on mine that the menu when brought up is clear and I can see it perfectly. The picture on all the inputs is just as described above though. BUT, like I said I can see the menu just fine. This leads me to believe that it's not the panel. Anyone have a solution to this, or at least know what could be causing it?
