My sony kp- fx532m91 has trouble in turning on it takes 30 to 60 minutes before it will open/on. and it blinks six time every 3seconds. what could be a possible remedy anyone can help me.

Iam thinking that 6 blinks means power suply make sure all voltages are right according to the board.Could be somthing is pulling down on 5 volt line or12 volt line. If it is a CRT which Iam sure it is then there is 150 volts DC or so for the flyback there is a high voltage block for the high voltage for each gun red blue and green.Check power suply horizontal output high voltage block focus and screen block.

Sony Projetion TV has horizontal blue lines across the screen

It is hard to tell from your description what is wrong--confirm actual model number for me.

I am going to attach some photos of what CONVERGENCE troubles look like--they may or may not look EXACTLY like your set but if you have something similar I can help you with more information.

If this helps you rate this solution as I do this here for free.

Horizontal blue lines with a slight blue wash in the screen

Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

Very fine blue lines veiwable when the background has black in it

You need to adjust (actually bit decrease) G2 volts (calls Screen volts) of Blue gun.

Hitachi 53sbx59b horizontal wave lines

I would check the main power supply for a bad filter cap. That could cause the wavy lines. The different colors are probably a problem with the convergence circuit. Try resoldering the convergence ICs first. If that does not resolve it replace the ICs. Also check for low valued resistors in that same circuit or pico fuses.

Mitsubishi #VS-45605

We had a blue cone on the screen. We have adjusted the sharpness, contrast, and cross hairs. The cone has almost completely disappeared, but we still have blue shadows. Could this mean a blown color tube?

Any suggestions would be greatly appreciated.

Blue screen with flickering horizontal lines

Sounds like the 1000uf capacitors on the FMT board need replacing. This is a common symptom with that chassis. There are three 1000uf caps that fail on that PC Board

Blue horizontal bows/lines

Replace convergence IC's,then check alignment.

Use OEM quality ==I use Panasonic IC's with no call-backs.
