2001 Sony KP-53V90 53 in. Rear Projection Television has a problem related only to the picture, the top and bottom of the screen are bowed into the middle, the video feed label and volume scale are also...

This is probably the notorious "light engine" problem that all of these Sonys of this design run into sooner or later. It is usually more expensive to repair that what the TV is worth, sadly. A Sony authorized repair center can confirm this.

I have a 2001 sony 53' rear projection tv model #KP-53HS30. It seems has a wavy section on the upper left hand corner and lower right hand corner of the screen. All the bulbs are working fine but seems...

Try this. The follow was found on tv-forums dot com by Zyntar...
There is a secret service menu to converge the Sony KP53HS30.
Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.
Procedure: (use the remote control for these steps unless noted)
1. Turn TV off with System Off (under flap on remote)
2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.
3. Use 2 & 5 to select the PJE Category.
4. Press 9 to get to fine convergence adjusting.
5. Press 6 several times to get the convergence screen of choice. I like the grid.
6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.
Note: Try to keep the grid even and squared up.
7. Repeat steps 5 and/or 6 for all parts of the screen that need it.
8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"
9. Turn off power.
TV is ready to use.

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.

I have A sony kp=53v90 tmier stand by light falshes twice

Well I believe you are on the right thought pattern.
I beleive this is an older CRT rear screen projection TV.
Could just possibly be a Power supply issue or a bad HOT 'High Output Transistor.' It could also be a flyback issue.
Will need to be taken in to a trusted service shop to have it looked at. May be a time to look for a new TV. Sorry!
