My standy light keeps flashing and every so often it sounds like its gonna come on then it dont

I young so dont rely completly on me but it sounds like your vehicles computer is having a malfunction you ca take it to any auto zone and the willl plug up to your car and find out the problem as for taking to a mechanic there just gonna try to find the most expensive part they can to fix ..

Two things to look at---------the lamp to see if shattered inside AND with it removed look where it faces at the color wheel--see attached photo.

Look to see if any segments are broken, missing etc. Many of the wheels fail in this way and some will have a high pitched or even fan like sound before they fail.

Some when really bad will make a grinding noise also. The set monitors the speed of the wheel and if it slows or stops the set will almost instantly turn the lamp off(if possible watch from area where lamp is to see if at turn on to see if it for a moment lights or not.

my system keeps turning its self off then the standy keeps flashing...does any1 no why???thanks

The fan could be also the problems too.The standy/temp flashing mean the fan not working or intermitten having problems.

switch tv off for 10 min and then back on.
tv should come on.
if this doesn.t work.you will need to replace main board.

I have the same tv and it did the same thing. I replaced my lamp and it corrected the problem.

This means Fan failure - A replacement will cure.

This generally indicates an issue with the backlight inverter loading the power supply. The inverter assembly is easily replaced in this panel and costs approx. $90-140 depending on your parts store. Please use caution when working with this component, it produces the very high voltages required to illuminate the screen.
Good luck to you.

This is is due to a faulty resistor probably the B+(R950)..On the power supply control circuit..If you know how to use a multimeter you can easily find the faulty one...And replace it.However if you are not good at electronics i advice that you give it for service coz its not gonna cost you too much..Dont delay the repair as it can damage the more expensive components in the Tv.
Good luck!

There is a short on the B+ line caused by a pulse going through the supply, How is your insurance, it may be covered. windman
