If the lcd lamp has been changed then the problem is with the inverter board, this board acts a bit like a switch to turn the lamps on, it is either a seperate board inside the set, although some lcd tvs have the inverter built into the power supply board, you will probably have to visit the manufacturers site for this information and they should be able to supply a board for you. hope this helps.

Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

Hi,Osram lamps average around 3000-4000 hrs.Normally 1 -1 1/2 yr.I do think the lamp went out.The ballast is a possibility,when it's going bad it will make clicking noises or attempts to light the bulb.I recommend to get the Original Philips lamp for they average 6000-8000 hrs 3-4 yrs.

Infocus IN72 - blinking RED light


firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

Head lamp keeps burning out. replaced head lamp at


You either have a bad ground or the bad electrical connection at the light socket is "simulating" a bad ground. This is putting a high resistance on the bulb and it's taking it's toll by burning out the bulb. I would start with a new socket, and CHECK the ground. If you still have the issue, I would run another complete ground wire and not even worry about checking the ground itself. the Stick

Power light flashed red 4 times then repeats no pic,new bulb/fan!


Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

Sony Wega kdf-55wf655 rear projection set keeps turning on and off


If picture quality is poor, be sure you aligned the bulb in the correct manner and be sure the cover for the bulb is not loose. Also, you might want to re check you picture setting as it might have gotten reset when you pulled the plug (I hope you pulled the plug when replacing the bulb).
Heres another solution (maybe temporary) to the problem of no picture and no sound for 30 seconds. I had my tv's power saving setting on "standard" before. After I switched it to "reduced", the problem was fixed. It has been almost two weeks without the problem. I think its a good fix until the new bulb comes in the mail.
