Hi my Sony Sony KP-46WT510 tv will not turn on. When you push the button the light blinks 8 times and the resets and blinks 8 times and so on but never turns on. Can anyone give me an idea what may be wrong with it and what to expect from the repair guy.
Thanks for any help
The High Voltage Block - part# 8-598-955-32 was an easy fix. It will take you about 30 minutes. You'll need a phillips screwdriver and possibly a small pair of pliers to remove a connecter (at least I did). While I did not take pics or write down step by step, here are some general instructions. Make sure that the tv is unplugged. Unscrew the panel. The screws are all the same size so don't worry about matching holes. Disconnect the wires to where they are connect. The thicker red ones that enter the HVB themselves are done in a "twist and pull" method. You will need to use this same method when hooking up the new one. There is also a small black cylinder piece of plastic around one of the wires. Make sure that you remove it from the old HVB and place it on the new one. You should be done with the grunt work. Place the cover back on. Check out this site on how to clear the diagnostic codes or else the light may keep blinking... http://www.iwaynet.net/~nesda/SonyBlink.html

Most likely you have turned on the sleep function. 2nd button from the left on the top of the remote hand unit. Keep pressing until "sleep off" appears on-screen.
Timer in user's menu is activated to turn off TV a specific time. Go to timer menu and adjust timer, then push cancel on the remote, this should reset timer to zero. Same with current time, adjust and select cancel, this should reset current time.
If you do not have the original remote, you are in trouble. Service tech will have remote.
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.
KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test. HQ Comments: Any load on the B+ line can cause 6 Blinks. Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.

The buzzing sound you hear is typically the FBT shorting out when you turn the TV on. If you open the back panel and watch the FBT as you try to turn on the TV you can see it shorting out. It will be obvious.
