Did you clean out the area where the bulb goes, and did you touch the new buld with fingers, or is the new bulb the correct bulb? All these are questions I would ask myself first, then if all are good, then in the bulb area there could be some other problem
If you lost video and assumed the fluorescent tube was at fault, you may not have guessed correctly.
There is a power supply (normally called an inverter) which may be separate or combined with the main supply that produces the high voltage the back-light requires.
The tubes, if bad, will have a well-defined dark area at one or both ends of the tube.
If the inverter has failed, there will simply be no voltage to ignite the gaseous tube.
The effect is the same but the solution is different.
Order a new bulb, easy to replace, just read the manual. In the meantime, go into Settings and change the Power to Power Saving, instead of Standard. Your bulb will work fine until the new one arrives.
The audio/video blackouts were in fact a precursor to the bulb going bad ( even though no lights on front indicated such as the manual suggests).
Replaced it, blackouts went away. Picture is noticeably brighter, so the bulb was showing signs that I didn't pick up on.
If you're reasonalby handy, the lamp assembly is an easy fix for approx $200-$250 .
You need to remove the front panel of the TV. If you look at the picture above, this panel is the light gray piece on the bottom of the tv. It is attached with plactic connectors. Just poo it off and then you will see a metal panel with some screws. remove the panel and then you will see the light buld casing. Pull it out and replace it with the new light bulb casing. If you did not purchase a new light bulb casing and bought just the bulb, you will need to take the casing apart and replace the bulb. Make sure to mark the wires so you will know where they should be connect to the new bulb.
In my experience with these models, if have found that your fault could be due to a blown bulb assembly. This can easily be checked by looking up the bulb replacement procedure in the user manual. The bulb should look clear and see-through to the tip of the filament. There must be a small class pipe inside which has a wire connected to the tip.
Any white residue or black discoloration inside the bulb indicates a blown bulb. You can contact your nearest Sony service centre for a new replacement bulb. Write down the "XL-xxxx " number as you will have much faster result than giving the model number.
