Having Trouble With Flyback

I am trying to change out my flyback transformer on my Sony KP-51WS510. Do I have to remove my D-board to change this out, also will there be any soldering involved, and I am having trouble pulling out the HV cord from the old flyback.

Yes you will need to unsolder the old flyback and solder in the new however its very basic soldering required. Yes the d board will have to be removed just remove the screws and then press the plastic tabs in that secure the board to the plastic frame. Then the HV lead has to be rotated 90 degress and then removed they come out quite roughly. Its best to grab onto theHV lead with insulsted pliers and then rotate and pull with a twisting motion to get it to release.

MY SONY KP-51WS510 LOOKS LIKE 3D AND THE IMAGE IS CURVED


The flyback as you discovered does not effect convergence. The convergence repair is different. This video should explain it further.

Tv trys to start. you'll hear audio for two secounds, no picture, then 8 flashing lights, repeats after a few secounds 8 more flashes etc,etc


There is a problem in the audio circuit or the high voltage circuits. Check IC406 audio amp, PS401, and 402. Check also the flyback transformer T8005 or the associative components around it or associated with the high voltage circuits on the D board. Try also unplugging the unit for an hour to allow the unit to reset and make the unit work. It sometimes resolves start-up issues with the unit.

Red stand by light blinks 8 or 9 times and no picture or sound


hello 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.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).

8 blinks is usually the error for a bad flyback. you can get a replacement at the following link and if your not sure which one your model uses click on the sony flybacks one at a time and it will tell which model they fit. Heres the link.

Arcing inside no picture


Most times arcing like this is from the Horiz. output transformer (flyback). The insulation has a break down and up to 30 KV will find the nearest path to ground. This would require a tech. to repair the unit. This repair will most likely cost around 250.00.
