Lampmay be going out. Look down inside of lamp, if there is a foggy look it may be going out. Also check to see if the fan is working.

Broksonic Flat Panel TV, tried to turn back on TV and Green LED light is blinking and screen pops up a few sec with white and colored lines and the turns off

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.
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.

LG LCD 42" sound but no picture

From this web site it says:
Powering Off
  • Many LG LCD television owners report having a problem with their televisions where the screen powers on, but then lasts only a few seconds or a few minutes before powering itself off again. The problem usually occurs with brand new televisions, and in this case is inside the television itself. If your television is powering off unexpectedly, contact LG so it can be serviced.

Panasonic TC-P50VT25 1 yr 3 month old powers off after 30 secs blinks 11 times pauses blinks 11 times and continues

The issue suggests either no voltage to that fan or it is bad--most of these all fans are powered from the same source.

I have seen this before---try swapping fans if they are identical--if another where you swap it now does not work--fan is bad.

Usually we (in the shop) if find this change all three fans.

Tv cuts off and green light flashes

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

No picture, but power is on...

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
