Sony tv KDF55WF655

I have a Sony proj. t.v. model number KDF-55WF655. Its 52 inch. When I turn it on its ok ,then after 10 seconds the screen goes black but the tv doesn't turn itself off. The green light flashes about thirty two times and brings the screen back. All this and the button never goes red. It keeps itself like in a reboot stage. Please help its only 2 years old.

    I have the same issue with my KDF-55WF655. It will turn on, then after about a minute the screen will go dark and the green power light starts flashing and eventually the picture will return only to go dark again after a minute and repeat the sequence...could the lamp be bad?

    Same problem on KDF-55WF655 55 in. Screen goes black and green power light blinks roughly 30 times then picture comes back on and light continues to blink about 7 more times then goes solid. Cycles thru this routine repeatedly with screen going blank after about a minute of solid green light.

    I got the same problem. Quite annoying. I heard the bulb might be going bad. The TV has had the same bulb for over 8000 hours of use so it might be time. Has anyone actually reslove the problem by changing the bulb?

    My Sony Wega also randomly looses the screen picture but not the sound. The green light continues to blink and then turns back on. The fan is working as I can here it shut off after I turn the tv off. It is the light that just randomly turns off and then back on.

    I also have the same problem. Has anyone fixed it yet?

  • cowden Mar 05, 2008

    Mine just goes black after about 5 or 10 min with no sound, the green light just stays steady, and then pic and sound will come back after a min or so. It will do this over and over again but randomly, sometimes every 5 min or sometimes maybe 30. I thought it might be the lamp, but having no sound is throwing me. Could use some help

I had the same problem. The sound and picture went off for about one minute and the green power light flashed green. Then the TV came back on. It sometimes stayed on for hours and sometimes went off again in a few minutes. The TV is just over 3 years old. Had the service people out and the problem was the bulb. It cost $420.00 to fix. He said our bulb lasted twice the average life. I wish that I had known this since it is a simple fix and the cost of the bulb on line is under $200.00.

Need a free manual for my Sony LCD projection kdf55wf655 tv

Sony has many manuals for their products on their support site. For the KDF-55WF655, start here: . Click on the Manuals, Specs & Warranty tab. Look for the Operating Instructions link on the left side of the site. This is a Javascript link so I don't know the full URL for the manual.

I hope this helps.

My Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?

Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

I need help. My Sony 50 inch tv is a 2006. The warranty ran out in June 2010. I heard a pop and then it shut off. Now the green light flashes 25 times and turns to the red lamp light. I can't reference...

Pop sound was broken lamp in tv, replace lamp to solve tv issue.
Please recheck model number as KDF-50EA10 seems invalid/ incorrect model number and nearest match is KDF-E50A10
If model number is KDF-E50A10 then required lamp part number is as follows...
F93087500 ... LAMP BLOCK ASSY XL-2400
and available with Sony Accessories Store for $200
Let me know if you have addition question or tv model number is other than above said (KDF-E50A10).

Blue Vertical Lines on the screen

It means the optical block is going bad. Contact Sony support. They will sometimes warranty these even after the 1yr warrany has expired. Have your model and serial numbers handy.

Sony KDF55WF655 TV ready green light blinks 30 times

Could be a bad lamp again. If this TV uses the XL2200 lamp, they are known for this intermittent behavior. If its not the lamp, a tech can access the self-diagnosis screen to see what's causing this failure.
