I think, your TV gives High Bright Green Light on screen and then goes to standby. Its indication of defective Green CRT (Picture Tube). Rear projection TV has 3 CRTs i.e Red-Green-Blue. In your case, Green CRT seems defective and need to be replaced.

This is a problem due to heating of some component in the power board or main board

this is the reason for the unit to turn off with out any reason.

this can be due to a bad component or a bad connection.

you will have to manually inspect the board for the problem.

The safety switch is turning off TV by itself. It menas there is a problem inside tv, a short, a blown capacitor od a faulty IC. Pcbs must be tested with a multimeter. Unless you are an expert electronic DIYer you will need a technician to fix this.

Hi,

this often indicates that the built-in protection system has kicked in to prevent any (further) damaged to the TV unit. Depending on the brand and model, the lights would be blinking signifying a code that could lead to the probable area of fault.

Initially, you could try to reset (unplug from the mains for a few hours), hoping that it is just a glitch and with the reset, system would revert back to factory defaults.

Hope this be of initial help/idea. Pls post back on the make and model, how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

When I power up, 5 seconds later this back projector TV turns itself off


t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

It's been a while since this post, but I may have had a similar problem with my Hitachi. With no reason it would switching on and off randomly. The problem was with a solder joint on main relay - it was cracked and would not keep the coil powered so i kept flickering on/off. This relay is located on the front of pcb, between high voltage area and the switch and on my tv it is blue. Check all four joints and apply some new solder onto them. Make sure the tv is not connected to mains ;-) Hope this helps

T.V. TURNING OFF AFTER ABOUT 5 MINUTES.


Go to Samsung.com for solution. There is a switch that just needs to be repositioned behind access door on rear. Fixed my HL-S5086W ok.
