The model you listed is a rear projection DLP set that uses a lamp and not a CRT. The part number for the lamp is 6912B22007A and is just the bulb itself. Meaning when your go to replace it you have to remove the old lamp from its housing and carefully install the new bulb in the old housing. You will want to use latex gloves so you don't leave fingerprints on the new lamp as it will shorten the life if it.

Sound but no picture


This is listed as the standard Television and if not let me know--it means it has a picture tube and is not a LCD or other type of set.


Answer is in that case someone needs to "look" inside at the neck of the picture tube with the set turned on---set should have 3 dim lights in the neck of the tube ---filaments like a light bulb---question is are the filaments lit or not?

Our 21" panasonic television is when turned on,


Hello

It is due the fault of its picture tube base socket. Picutre tube base socket can be located at the picture tube card connected at the neck of the picture tube. It is the socket that connects the picture tube pins to the circuit. It can be resoldered out and can be replaced.
Open your tv. Locate the picture tube base card, can be seen connected to the picture tube neck. It is pluged on to the picutr tube, and can be pulled out of it. Be sure not to make any tilt of shake while pulling it out. Just pull it back straight, may have to apply some backward pulling pressure. Resolder it out for the board and go for a same type and number. It can be available at most of the electronc sparepart shops. Replacing it will solve your TVs problem. OK
If you need furthermore asistance, feel free to get me through Fixya.

Tv keeps turning itself off and the white in the picture looks alittle off.


To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

Where can i find a replacement picture tube for my akai 42" LCD tv?


Due to residual electricity, replacing a TV's picture tube is very dangerous. I would NOT do it myself. Besides this, getting a new picture tube frequently costs almost as much as a new TV would.

You can contact a local repairman (if it's still under warranty just send it back), and get an estimate, but seriously consider getting a new TV.

Picture has lines going across


No picture tube is cheap to replace. Especially a Sony tube. And besides the cost of the tube there's the labor cost to install it and some tedious adjusting needs to be done to set up the replacement. When a picture tube fails it's time to replace the set.

Now having said all that, there are different kinds of lines that can show on the screen. Some are because the tube is bad, but others can come from less expensive parts on the circuit board in the set. Without seeing the lines for myself I can't tell you about yours. If you are wanting to keep the set, I would suggest having a qualified shop check it. The can tell you for sure if it's the tube or not, and give you an estimate for the cost of repair.

Susie, you either have a shorted green drive transistor or more likely a shorted cathode inside your picture tube, transistor repair is a cheap fix, picture tube means set is not worth cost of repair, hope this helps
