Whenever i get these types of problems especially in sony sets,i first clean all the video related boards,i use fast evaporation paint tinner,to get the flux and grime off,then resolder all or most of the flat pack ic`s (be carefull,if you cant do this,then dont) use a magnifying viser to check each ic for bridges and solder splashes,wash boards again with tinners after resoldering.This works for me 99% of the times.If you need the schematic for this set request it at computec40@hotmail.com

You have a weak capacitors in the power supply. Your description has enabled me to say this is the solution. We TV techs call this "breathing". You may control some of this with raising the contrast and brightness to see the picture stabilize.You will need a TV tech to correct the power supply. I have not worked on projection TVs for some time. This is a classic problem with a classic fix. Thanks for asking and show all hands of support!

I have a Sony KP-53V90 53 with no display and red light flashing


This is a good one. Your TV "looks" at the feedback coming from each picture tube in your TV. When it doesn't see what it expects, it kicks out a 5 flash. Most commonly, the correct signals never got to the picture tube(s) and that's why the feedback was abnormal. Which brings us to the most common solution: C boards, they attach directly to the bottom of the picture tubes. Figuring out which one has a problem... that's another matter. Due to the age of the TV, parts costs are rising. Each C board (3 in the TV) runs about $100 so guess work can be expensive. I hope this was helpful.

Try (with your remote) hit Display + Channel 5 + Volume - + Power hit each key within 1 sec of each other and the tv should go into error check mode on the screen and display some data, record that and google.

Flashing screen


% blinks for your model means a video output abnormality. which translates into IC7101, IC7201 or IC7301 on C board circuit is faulty or else its transistors Q510, Q516 or Q524 are faulty on the A board. I would check the transistors first for being faulty and if they check out then suspect one of the ICs

Screen Flashing


In a Sony TV, the most common cause of the picture flashing on and off is a weak picture tube. When the set was new, it took about 5 to 10 seconds for the picture to appear once the set was turned on. This is normal. If you have been noticing that it has been taking longer and longer to first appear, this is the clear signal that one of the picture tubes is getting tired. There is a circuit called IK Blanking that monitors each picture tube and adjusts them as the tubes age, so you always see a good picture. When one of the tubes has weakened so much that it cannot produce enough brightness in the picture, the circuit shuts the picture off completely. I guess Sony does not want you to see a tired, dull picture. When the tube is right on the edge of being too weak to keep the picture on, the picture will flash on and off, and it will also take much longer beofre it first turns on. The good news is that the Sony picture tubes always respond beautifully to reactivation (CRT Recharge) but you will need a qualified tech familiar with Sony projection sets to handle that repair for you.
