Question about GE 46GW945 46" Rear Projection Television

1 Answer

Have sound but no picture

I have sound but no picture. This happen all of a sudden turned on tv no picture, had no lighting, no storms, no power surge. However a couple of times in the last 2 wks when I turned on the tv, the picture was distorted looked like you were looking through a bottle, picture was rounded and the colors were off. Turned tv off & on and it cleared up. I did try to unplug the set, let it sit for 2 days same problem.

Hi there!
One of reasons your tv not working, the thunder storm /lighting possibility has burnt your Tv micro processor. get a technician to check the power supply section too because during the thunder storm your TV circuitry received excessive voltage .
If is the main processor is burnt you have to change it for the TV to work .

A power supply section problem is what your experiencing which is a part of your television set. A defective MOSFET or switching transistor could be a problem that holds the power of your television. This is a very fast switching component which is very sensitive to current surge. A sudden surge of electricity may have caused this component to malfunction or become defective. A qualified electronic service technician can figure out the problem.

Red power light flashes. tv won't turn on.


how old is your tv?? ours was 2 1/2 yrs old it was a 40in lg hd ready lcd tv it just crackled and turned off one night same as yours it would turn on but with no picture or sound....we took it for repair and they said it was something inside that is basically impossible to fix...it would have cost more that the tv itself. BUT trading standards say a brand new tv should last upto 3yrs...you need to get a free qoute nd if they cant fix it contact trading standards and the tv MANUFACTURER not the shop where you got it....you NEED a reciept to do this for proof of when you purchased it...hope this helps :0)

The TV won't do anything


Power surge and lighting do a lot of damage ,you will be lucky if you only find the bridge rectifiers shorted(maybe just one) and a open fuse,that will give a place to start but expect more extensive damage.Be carefull
