The applicable code(s) would be found in a compatible remote control.

Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

check your cable coming in from your provider, it may be loose. if that' s ok then rebout your provider box. if that doesn' t work, check the settings on your tv with the remote that came with your tv.

I have tried playing with the settings on my blu ray player and then hooking it up to the tv and it doesnt fix the problem. 1080p/24 is turned off. Here's my story.

For the last 3 months, I have had a constant headache with Westinghouse and Toshiba.. My Toshiba BDX2250 worked fine with my Westinghouse but the blu ray player broke after 7 months so I returned it to get a new one but they didn't have any more of those models and gave me a newer model - BDX2300. That one gave me the start up screen and then went black - doesn't play movies, audio, can't get to the start up screen.. But, it works just FINE with other tvs other than Westinghouse. It worked with my parent's Vizio... Then, I got another one of the same players cuz I thought it was broken and then I realized it just was the tv or the model. So finally they send me another newer model the BDX3300. This one does the SAME thing. I call Westinghouse and they constantly say a level 2 tech will call me back but they've lied constantly. One lady even told me that level 2 techs don't even exist. 10 minutes later, she said she would get me on the phone with a level 2 tech because 2 were standing right next to her (wait, what happened to them not existing?!) and she comes back from putting me on hold and never put me on the phone with them! Now the 3rd person I talk to tells me Westinghouse isn't compatible with Toshiba blu ray but I ask if its all the tvs and she says she doesn't know she doesnt see why it would only be one but I wonder if its cuz this is a black friday tv? But then again, I think Westinghouse just SUCKS and none of them work with toshiba at all cuz they lie to me constantly. They tell me different things EVERY time. I hate Westinghouse and am filling out a complaint to the Better Business Bureau BBB now. This has been a horrible experience and I will always buy the more known, expensive brands from now on!!

This T.V. is less likely that capacitors made it go bad. There is probably a MOSFET that went bad or the H.O.T. (Horizontal Output Transistor.) There could have even been a power outage that caused the main fuse to blow. You never know unless you look inside of a dead T.V. if it doesn't have a blink code.

this is looking like a common LG problem our tv started doing this tonight

Philips TV model 34PW9815 the LED on the front of the unit turns green when first plugged into electrical outlet, and then immediately starts to flash red. nothing on the unit works and it doesnt respond to controls either on the set or the remote

try changing the batterys. If its a universal remote reprogram it again.

Either there is a bad fuse under the cover, or the power supply is shot. THe fuse should be a glass fuse which has a wire inside of it. The wire should extend all away across the fuse. If it doesn't than the fuse is bad. If fuse looks ok, the power supply is probably shot.

I also have this model. A few months ago, when I turned on the tv, it told me my lamp was in need of replacement. just yesterday, my tv did the same as you....the blue light flashed and then the lamp light kept flickering. All I can say is your lamp needs to be replaced.
