When I turned the TV on, then the picture start blinking each 5 secunds, just the video get off end get on, the high voltage still that. I increase the screen voltage to see the picture on when the video turn off, Yes the screen stoll on. Please sumbody know fix this problem? Thank you for you help. I'm sorry for mi English

Re: Please, Help me fix my TV
It sound like you have abad picture tube. Iknow this is not the answer that you want to hear. Sony's have video blanking circuit built into the
video processor(in the jungle IC) when the emission of all three gun fall out of an acceptaable range. the screen blinks and when you
turn the screen control on the IHVT all you see is re-trace. Some times there is a current limiting
resistor in series with on lead of the heater on the crt board. By changing this resistor from 2.2 ohm to >.1 ohm @1/2 watt you can sometimes increse the filament voltage to the
point that the blanking stops. This is only a temporary cure not a fix. The picture tube is probably bad. Scrivitron

5 blinks error means that there has been a white balance error triggered either due to faulty video ICs on either of the CRT boards or the CRT drive IC on the A-board is faulty. I do have the service manual and can help you fix it if you know how to use a multimeter and solder. I should also tell you that this is high voltage electronic device(especially the near the CRT boards). The CRTs act as giant capacitors and hold voltages of upto 30,000V for several days after the set has been unplugged. I did not mean to scare you but I just wanted to give you a headsup!
5 times red standby light blinking shows problem with ballast supply board in Sony KDF-E50A10 model tv, ballast supply board provides high voltage to lamp to produce high bright light. Please check/ replace ballast supply board in tv by local tv repairman. Thanks.
check for any cold solder on the high voltage section of your tv A high voltage section is located at the power supply section, this is where the power cord is connected.resolder them,the horizontal section it is where the plyback transformer is located resolder them and the CRT board this is the boad that is attatched to the picture tube...good luck
The 7 blinks usually indicates a high voltage shutdown situation. Without the specific model, I can;t give you details about parts etc. The options are a defective flyback transformer or problem with the voltage regulation circuits. Please update this with the model number and I'll post additional details as soon as I can.

The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?
