We have just replaced the bulb on our Sanyo TV PLV65W. We have replace bulb before and always worked. This time it keeps asking for new bulb and will not come on

There are several reasons for short lamp life. Inadequate ventilation or clogged cooling fans, a bad lamp driver or lamp ballast (they are the same) and the use of non-original Sony lamps, as the aftermarket replacements are known problem causers. Remember too that the number of times the lamp is turned on and off is a BIG factor in how long the lamp will last.

If there's no obvious removable cover over the bulb (most often on the rear or side) and the owner's manual doesn't address it, then disassembly will be required.

You'll need to remove the outer cover (wrapper) to get to the bulb.

Always unplug a microwave before removing or installing any bulbs.

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.

If not, chances are you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

If you don't have your instructions, please reply back with your brand and model number.

Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.

On a counter top model, be sure it's unplugged, but otherwise ignore the instructions above this paragraph.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had locally in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

I bet the area around the lamp shows signs of warping and/or cracking too? This is a VERY common issue as the fan that sits above the lamp gets clogged with dirt which allows the lamp to over heat which decreases the lamp life as well as distort the plastic casing around the lamp. The fix is a thermal fuse kit and a new fan and of course a good cleaning of the other fans in these TV's. This should be performed by a service technician.

Seek a repair shop. You most likely have a ballast power supply issue.
