SOURCE: TV does not turn on/red led flashes 7 times in front

this is common issue with this model and through your troubleshooting is tied to y main board. blinking led on logic main in normal operation. when replacing y main always good idea to replace y upper and lowe buffer boards as they complete a circuit and sometimes replacing one without other could cause additional failure on remaining boards

I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.
thanks

Sony Bravia KDL-40V300 won't turn on.


Unfortunately 5 blinks is a LCD panel error. The only way to fix it is to replace the whole LCD panel. This is the most expensive part in the TV.
part number: 1-802-488-12
List price: $1336.32
Core charge: 1790.00
You could try to replace it yourself but would need to take the whole TV apart by first taking off the back cover, then removing all the boards in order to get to the panel before putting it back together but I would just recommend buying a new TV as the price of the repair exceeds the price of a new TV of the same size.

Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.

Best Regards and Semper Fi

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.
