Question about Sony Grand WEGA KDF-50WE655 50" Rear Projection HDTV

1 Answer

I replaced the bulb in my KDF-50WE655 and now the TV begins to power on, the fan comes on, then it shuts off. I put the old bulb back in. Same Result. I have tried this several times. The TV powers up (not the screen) and then I hear the switch immediately shut it back off.

Hi,
There would be red light blinking in TV front, its an error code, let me know how many times it blinks, as there is 3 seconds pause between blinks so count pause to pause and post back to find out problem reason.
Thanks.

    Three blinks every three seconds
    ==============================================

    OK, 3 blinks error shows that Lamp Cover is either not placed back in its position or not fixed properly.
    Please check Lamp Cover, its first thing on lamp box that was removed to replace lamp, make sure its fixed correctly because there is safety switch that has to be pressed by lamp cover.
    Hope this info will solve your TV problem.
    Thanks.

Power light once, then power and OPC twice simultaneously. what would that be?


Hey Vince, not sure of your model, but this may help. Last year, my older Sony started acting up. I would hit the power button and the red light would flash, fan would come on, no picture and then would power down. I bought a replacement bulb from Amazon and that solved it! Still using it today! Hope this helps! http://www.amazon.com/KDF-42WE655-KDF-50WE655-KDF-60XBR950-KDF-70XBR950-KDF-60X8R950/dp/B003ISY34U/ref=sr_1_2?ie=UTF8&qid=1386773313&sr=8-2&keywords=Sony+replacement+bulb&tag=donations09-20

Green light flashes for about a minute, fan does not turn on and there is no picture or sound.


unplug all cords and cables from tv, then unplug tv, wait about 5 min, plug tv back in this resets, the "brain" if samething ....see if your bulb is glowing, or tv is hot to touch...always clean the breather slots or holes so fan can push or pull cool air..most of these tvs have a auto shut off for safety if fan has faulted out.....you might just have a DONE fan unit.

Tv turns off for a minute and comes back on


Hi,
if tv turns On itself after shuts down then its symptom of weak lamp as current lamp is reaching to end of its working life, tv requires lamp replacement.
Lamp replacement procedure would be written in user manual and its easy. Please buy Sony original lamp for good picture.
Let me know if you have additional question.
Thanks.

I have a Sony KDF-E55A20 rear projection, it will shut off pic/sound for 15 seconds then come back on for 15 min...then the same...I had a problem with this about 3 weeks ago and cleaned the bulb vents and...


Hopefully it's still under warranty or you purchased an extended warranty. My concern is that it is either a power supply issue or a lamp ballast issue. If it has overheating in the past then there may be other issues going on.
Would suggest bringing it into a good trusted service shop.

I have the 50" SXRD XBR1 grand Wega; This has been a great set for 3+ yrs. A flashing red light promted me to replace my original buld (this site). I now still have a flashing red "power" light, shuts off...


Its the fan that cools the bulb. Try turning on the tv and look at the fan to the rear of the bulb. If the fan is not spinning that is your prblem. The tv has a safety switch that will cut off the tv if the bulb gets too hot. I was able to tap my fan with a pencil and get it spinning, but that is just a temperary fix. After a while, you will find the fan will stop working all together and it will need to be replaced.

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?
