Not that it is pertainent but it would be interesting to know which ICs you replaced and what caused you to suspect them; was the set dead before as it is now?
Generally, no video and no sound points to a power supply failure. Sometimes they will get slow at turning on, and others may fail completely; these two failure types can indicate different failure modes.
The type of failure that causes hard-starting power supplies is often cheap to repair whereas a failure that suddenly occurs can be more costly and involving more labor to resolve.
Pasted below is my usual suggestion for suspected power supply failures: --If it just fails to turn on, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself. 
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

 
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
 
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

I have some distored blue color across the screen


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Still issue with convergence after replacing ICs


The most likely cause is shorted convergence chips and possibly a few pico fuses.

Phillips 60in projection,rred/greenish 3d effect


the two resistors were likely burnt out with a convergence IC (chip). these are usually a stk392-120 on a philips, or simmilar. the alignments can be very tedious and difficult. what needs to be done is replace the ICs that control the colors that are mis-aligned. you might see that the green is square and straight, but the red or blue is off. in most cases, i would just change both convergence ICs plus the bad resistors. then go to your full re-alignment of convergence to fix the picture. hopefully the previous owner didn't mess anything up too much (if they changed anything on the CRTs ie yokes, lens focus, centering magnets it could counteract your electronic adjusments). before you put too much time into it, look to see that all 3 colors are atleast focused and it appears that the CRTs have been left untouched. once you get circuit repaired, you will probably want a service manual to help with alignment. this complexity may bring you to want to just pay for this repair, could run you anywhere from $200-400 depending on severity and local rates.
