My sony did almost the exact same thing. I removed the bulb & cleaned all the dust out of the cooling ducts & the screen on the bulb was full of dust. That bought me about a month, then I replaced the bulb & haven't had a problem since(over a year ago). Just make sure you NEVER touch the glass of the new bulb with your hands,oil on your skin will greatly shorten the bulb life! I found a bulb at a local electronics store for under $200.00... don"t forget to clean dust from cooling ducts,& make sure cooling fan is working, bulb gets extremely hot!
If you have a voltage meter you can pull the bulb out and check for continuity by placing the probes on the power plugs of the bulb. If you have continuity the bulb should be good, and it may be the lamp ballast.
If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.
Hi, Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number... A1085447A* LAMP BLOCK ASSY XL-2200U It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.
Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.
it works!! First i took off the front panel. Just check your manual
for instructions, very easy to do. If you do not have a manual just
down load one from google.. The instruction are easy to follow. The
screw they have you loosen with a alan wrench is attached to the
plastic, so you do not have to worry about dropping it inside the tv.
Removing the lamp was simple. once out you will notice on either side
are two small mesh screens. One of mine was 80% blocked with dust, the
other side was only 30-40% covered. I used a vacuum to remove the
blockage, i did not want the dust and dirt to go inside the bulb. i
then cleaned all around the lamp. Reinstalled, and we are go to go.
The kids are happy and i am happier since my wife not be buying a new
TV. if this does not work it is time to replace the bulb.
total cost of repair $.00
time required to fix, less than 15 minutes.
Also when my TV was loosing sound and picture and then return. I did
turn off my TV, then turned on. I nothiced a red blinking light. Mine
flashed 5 times. After some reserch, 5 times is video related, bulb or
video board. google red flashing light with the model you have and you
will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.
I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is. no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
