Punch yourself in the face REALLY hard and then throw the TV out the window and buy a 60" Plasma or a 52" LCD

Sounds as though the system may have overheated. Do you regularly check the filters and clean them? An airduster can also help to blow dust out of hard to reach places.

I have a infocus IN35 that at 100 hours burnt out a bulb. Thinking that it was just a bulb problem I bought a new bulb and it lasted 20 minutes. a shop said its probably the ballast that is the...

It is not a common problem. Ballasts rarely need repairs. Have you reset the lamp hours to zero after installing new bulb? If, yes to confirm about ballast please ask the TV repair shop man whether previously he had repaired any DLP projector. There is lot of difference in technology of DLP projector & TV (except DLP Projection TV). The problem could be in the projector main board. The lamp lights after getting Lamp ON signal from the projector main board. As the lamp ignites the ballast sends the signal of Lamp Lit. If the projector board senses that any blower/exhaust fan or colour wheel is not running then it will send a signal to Switch OFF the lamp. If you are tech-savvy then do as follows to check about lamp & ballast. Remove 5 pin connector from the projector. Connect projector to mains supply. Get a 5V DC power supply. Connect +ve to pin 3 & -ve to pin 4 of the ballast connector from this supply. The lamp should light. If it does not light then there is problem in the ballast (if the lamp is new). To give a chance you can check it for your lamp which lasted 20 minutes. Generally ballasts are made by OSRAM. You can get the ballast from OSRAM dealer. You will need the part number for that. Take out the ballast, it is there on it.

you can play TV through any projector if you use an external tuner. This could be a satellite tuner, freeview box of similar. It has some type of aerial, cable or satellite input and handles channel changing etc, and sends a picture to any attached external display.
Most tuner type devices will have a Scart or 3 x RCA outputs, modern equipment may have DVI or HDMI. Avoid HDMI initially if possible would be my advice, simply because the copyright protection can be a real pain. You'll need to make separate provision for audio (eg, attach your hifi to the tuner)

Dlp projection, keeps switching to standby, also sometimes will start up and the picture goes blank but the sound remains

The lamp may be out. Projectors need high voltage/wattage lamps. They tend to only last 2000 hours or so, which is about a year or two with normal use.

YPbPr and YCbCr signal

with component, if there is not a solid signal, it'll go blue. if the dvd is dirty, the player is dirty, or any other break in signal, it'll go blue. clean your dvd and/or player.

Hi there

This could possibly be your Ballast ( lamp's powersupply ) that is faulty.

It will either need repair or replacement.

Hi there

You'll have to settle for the ordinary Composite input on the Projector.

You do get a scart to composite convertor from most good PC & AV shops.
