That is a video fault.
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.

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.

This is a common problem an a failry easy DIY fix.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Hi sandersonkie,

Sad to say because 4 flashes of the led light at the front panel is an error code for faulty "LCD Panel". This is the expensive parts on the unit, almost same cost of a new set if you are going to send it in for parts and labor. Check if your unit is still under warranty/extended warranty period, avail it because the manufacturer will fix it for free. If not, new unit is more practical than to send it in.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

How can i fix str for sony tv/klv-19t400a?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

We have a Sony Bravia lcd tv model KLV-S40A10 - no power


Hi,the problem is from the fuse in the tv,it's blown and it's a means of in-built security against power fluctuations from damaging the unit,so the solution is to replace the fuse of the TV to restore your unit back to a normal working condition.

Be cool.
