No, you do not need to replace the bulb. Before doing so, check the capacitors. Most of them are Chinese made, therefore they bulge out. 1st, take your back plate off, inspect them for any bulging, if present, remove the whole board and take it to an electrician which in turn will remove the bad ones and re-solder the new ones on. I know this, because my TV stopped working while I was deployed. After doing the research myself, I got it to work. It's been over 5 years since it's last issue.

The screen is almost totally black.


You may need a new projector bulb for your tv. Search for "JVC Projection TV Replacement Bulb" + your tv model number on amazon.com and you should be able to find one.
Once you have the bulb, refer to your TV manual to install the bulb.

Turns on but dosn't show any video sounds like it wants to start but only the blue power light stay on got sound but screen stays black


1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

I will be doing something and my screen will flicker then it goes black What can I do to fix it? Thank you.


If it goes black and the power is still up then you need to replace the inverter. This is most times the problem and very common. The other possible problem is the bulbs, however the inverter is not very expensive and reletively easy to change. It is located just below the screen behind the besel that is around the screen. If it turns out to be bulbs you will need to look for a replacement screen.

My monitor works for a little while, then goes black.


Your power-inverter board needs an overhaul.
Probably in need of the standard capacitor replacement.
OR
a bulb in the screen is bad (a bad bulb will usually show symptoms)
It will flicker, or will look pinkishish for a bit or dark in the middle top or bottom of the screen.

Black screen


Sounds like the bulb again. In the manual it says that the power light flashes to let you know that the bulb is bad. When I got a replacement bulb, I noticed that the wiring on it was opposite of the one on my set and had to change the wiring to match my set.
