I have a phillps TS3259C that will not turn on. Changed the BU508 or BU520 regulator because it was shorted and also changed the flyback OV2076. The response on the tv is the same and when I try to start it you here a clicking sound by the flyback and if you hold the power key down it keeps clicking. The regulator is not shorted but it still doesn't work. Please help me out.....
Check fuses on the secondary of the chopper transformer as well as the fusable resistors.try isolating the frame ic and the audio ic as well.philips tv's tend to be very protective especially when something is shoting

1 Soldering problems 2 line transformer flyback circuit capacitor and ( BU508 ) or equvalent or other transistor shorted, bulget or defect capacitor sync ic or the power supply solderings supression coils and a few more things .
check for defective regulator at the power supply section and shorted horizontal section. if you don't have an idea how to trouble shot this unit i suggest to leave it to a trained tv repairman to fix the problem. atleast you have an idea what to expect when you hire somebody to do the job good luck.
Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not re-solder 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 (negative).
Hello Chech whether AC power get into the power supply regulator section. Just open your tV, and check it. There is a fuse [ glass cartridge type] on the power supply section. Check whether it has blown up or not. If blown up, make sure that there is some shorted components at the power supply section check it.
Hello Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. Check the power supply section for any loose solderings. Resolder all suspected solder points by applying a little more solder, without making a solder bridge short in between close solder terminals. OK.
In the past, my experience with Sonys is that you need to use Sony parts to successfully repair them. Also you might have a cold solder joint which creates an arc when you turn it on.
This arc will cause a "spike" which could possibly take out the regulator.
