I have a sony trinitron kv-32xbr400 it works but the picture is almost like its out of focus it has lines running thru it
The description that you give indicates a video problem, it is a situation where the picture tube is over driven and makes the picture bloom and produces white lines on a angle, this is caused by an open resistor or a shorted video driver usually located on the back of the picture tube, "video board"

KV-32xbr400 switch problem
Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it. in yor case you have 5 blinks that´s why the last is short to be possible the count..Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

    Sony kv32v15, Red screen with fine horizantal lines then shuts off
    I would suggest to measure the 200 volt B+ at the CRT socket. If that voltage is found to be low, disconnect the socket from the CRT and measure again. If the voltage reading returns to normal you may have a defective CTR.
    Also check for open or defective diode on flyback transformer for the 200 vdc source.
    I would also suggest to take all the necessary precautions since you are working in a very high voltage area.
    Good Luck.
