My Sony KDL-52xbr4 screen is black.

The Sony emblem and green power light on the bottom of the tv still light up but flicker off then back on probably once a minute or so. Otherwise the screen is solid black from startup.

This can be the panel itself, and or the matrix decoder/driver boards. The cost of this type of repair can approach the cost of a new set. From your description, I am thinking it is the panel itself that has failed.

Parts for your set are from Sony only because there is no third party manufacturing for these types of parts and assemblies.

Usually, when these types of sets become defective they are usually not worth servicing. During warranty the manufactures generally give a new set to the client, or they give a re-built set which has been built up using parts and modules from other sets that came back for service and had different types of problems.

If you know a tech is is good at servicing these types of set, maybe he can find a number of scrapper set of the same model to take parts from. You just have to hope the ones he finds have the same types of fault.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Sadly, a replacement screen itself would cost more than the TV is worth.

Here are a couple of web sites selling the replacement screen:

I know it seems like a crazy price. But, TV manufactures buy a mass quantity at a lower price. Where buying just one screen panel cost an arm and a leg. Buying a new TV is the best choice money wise.

My friend has a Sony Projection TV model number KDL-52XBR4 and yesterday he had no picture and the lamp light which is on the front of the tv and is green is blinking. Is the lamp bad.

Unplug the unit from the power supply and wait 5 minutes.
Replug the unit and see if it operates normally. This is a hard reset.
The blinking light is usually a sign of something faulty. It could be hardware or a software issue. Sorry. Not enough info to tell more.

Sony KDL-52xbr4 screen is black

These 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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

Sony 52xbr4 screen flickering

Fault with the main power supply regulator board. Ubnormal DC voltage output from it. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.

Lines in screen

They are stuck pixels...

There are some that say sending strong images that change from to color to color can help unstick them, but I say only dissassembly and cleaning of the contacts (there should be 2 ribbon cables, one for top, one for side) that probably got dust in it. Call it in under warranty if at all possible.
