Question about Televison & Video
My 3 year old Sony KV-34HS510 will not turn on. Little red light blinks. What is wrong? What do I look for? Can I buy a part to fix it?
If I unplug it, then replug it, I can hear the tube energise, then some relay clicks. When I press the power button, more clicks, then nothing except a red blinking light.
Thanks in advance.
Sounds like a power supply problem. The TV is failing its POST (power on self test) and tripping a relay to protect itself. Time for a service call :-(

Listen up Mike, i'm not going to explain this again. Just because you can melt solder with a hot iron doesn't make you an electronic technician. There are steps that have to be taken in order to resolve your problem. Voltage readings, signal readings, and wave form readings that can only be done using a probe from an ocilliscope machine. These findings and ONLY these findings are going to aide you in your quest for the repair of your sony TV. Without them you will never fix your set. Oh, sure you can take the easy and most expensive route and replace boards that the problem may or may not be coming from. And if you go back and read my notes that I've written back to you you will see in plain black and white that I do give you the board letters that might have to be replaced. And yes, Sony gives their boards letters to distinguish them from one another. And if i didn't get back to you sooner i'm sorry, I do this for a living all day everyday so don't cry about not getting FREE information back to you in a reasonable amount of time.
Dead and the timer LED flashes 6 times.
Component failures causing this error could be:
1. Found that the a defective Flyback T8001 caused Q8013 and Q8014 to short out and
R8051 opens up.
2. B Board was loading down the 5v line.
3. Video Output shorted causing over current demand on FBT.
4. The TV shutdown and the LED flashers 6 times, 200 volt line comes up.
Found C6590 on the D Board was faulty.

Because, I actually have repaired a few dozen of these TVs and Believe me when I tell you that there is always something new found wrong for the same problematic symptoms.

The blinking 6 times error code means Low B+ (OCP/OVP) over current protect/over voltage protect. The +5 volt line could be overloaded or shorted or IC504 could be faulty. Three possible boards that these problems could be on. The A, B, or M boards. I suggest taking it to a Sony authorized service center if you're unsure of what to do.
