PC to TV Hookup
It is very likely that TV supports only some resolution while in vga mode. I would try 1280x 1024 and keep changing it lower until TV recognizes signal from PC

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.

Here's a link to the manual and I can't find anything about factory reset. http://www.hdtvsolutions.com/pdf/465B(zenith).pdf Why do you want to reset it?
Lamp has been replaced but TV wont power up?
If the lamp is a known good one, the next most likely suspects are the lamp ballast/power supply board or a mis-aligned lamp door. There's an interlock switch which opens when the lamp door is removed. Try removing and re-installing the lamp and the door.
Lamp indicator blinks red
There is a problem with the lamp or around it? When it turns Orange, the lamp is at or near the end of it's life & needs replacing. What does the temperature indicator show? Orange, Red or Red Flashing? If not, then there is probably accumulated dust around lamp area
Why is the screen is blue when tv is on?
Model prone to bad optical light engine---blue all over or most of the area---there is also a board on top of the engine that can cause it--I would forget it in either case as likely too expensive to fix.
Hi...the yellow haze is probably the blue filter is burnt and needs replaced. This is very common in Zeniths. There are 3 color filters in the Zeniths blue (pinkish in color), green (grayish in color) and the red (it is red). The #1 problem in this TV is the blue filter is burnt and it is an easy fix. It could also be the LCD cube is bad. I would try the blue filter replacement first. It will probably do the trick.
