If you get sound but not picture, clearly it is not PSU assy.

If you just replaced the lamp, ensure that lamp door is properly closed , and try reinstalling the lamp first.

If it still does not work, then the problem is the small AC board that provides high voltage to the lamp , this is called ballast board.
Also problems on DM board can cause same.
If color wheel is not spinning it can also be a defective color wheel.

Testing the ballast board, and the DM board is not a task for the home user, you need to read AC voltages inside TV with TV plugged in, and this is a job that must be done by a tech.

Below there is the troubleshooting diagram for your TV when you get sound but no picture:

Pull out the replacement lamp, grab trusty screwdriver (a fine-point philips with a long shaft ~8" was the perfect tool), and unplugged the TV. Get the plastic lamp access cover off (on the right side of my TV, around the back, near the bottom--two screws). At this point, be very careful touching anything inside if your lamp has just been on--items may be very hot. Take out the cage that goes around the lamp (three screws) and draw a diagram of how the cables were attached to the halogen bulb. After that, undo the cables affixed to the lamp itself, took out the top bracket holding the bulb in place, and loosened the other two brackets. Then pull the old bulb out, put the new one in, and reverse all steps.

LAMP HOUR RESET ON TV
Note: This does not require a service remote.
1. With the TV on, press and hold the MENU button on the TV front panel.
2. While holding that button, press and hold the MENU button on your remote.
3. Hold both buttons for ~5 seconds until the service menu comes up on the TV.
4. Release the remote MENU button first, then the TV MENU button.
5. Press and hold the ENTER (or OK) button on the TV front panel (see Notes 2 and 3).
6. While holding that button, press and hold the MUTE button on the remote.
7. Hold both buttons until the Lamp Life Hours show up on your TV screen.
8. Release the MUTE button first, then the ENTER button on the TV front panel.
9. Make a note of the lamp hours if you want.
10. To reset the lamp hours, press the SELECT button (the one between the four arrow keys with two concentric circles on it) on your remote.
11. It will ask you to confirm the reset--press SELECT again to confirm.
Note 1: To verify you've reset the hours, you can repeat steps 1-9 above and then just press the EXIT button on your remote.
Note 2: One person on a forum claimed that steps 5. and 6. above have to be switched.
Note 3: For a 44SZ8D TV, replace step 5. with:
5. Press ENTER on the TV to enter the position adjustment
5a. Press and hold ENTER on the TV front panel (the TV will re-enter the menu; keep holding ENTER while you press and hold MUTE on the remote. After approx 5 seconds, the lamp life counter will appear).

MAKE SURE THE LAMP DOOR IS SHOT TIGHTLY AND PROPERLY OR THE SET WON'T TURN ON. IF YOU STILL HAVE A PROBLEM AFTER THIS YOU MAY HAVE A PROBLEM WITH COLORWHEEL OR BALLAST

    you will have to remove the bulb, use a voltmeter, put it on the dc setting, place one probe on the side of the bulb socket, and the other probe on middle of the socket. Otherwise look inside your bulb to make sure the wire inside are not broken. If it's broken it's bad. If you get power to the socket than the ballast is good. If you have sound than the power supply is good.
    If you don't have power to the bulb, than the ballast is bad. You will need to look at the bulb to see if the wire still goes across. And you will have to buy or use a volmeter to see if there is power to your socket or other components.

You need a color wheel--common on these sets. Get a real phillips bulb and you should be set for awhile. The cheap generic bulbs are fine to get you through a few MONTHS....but NOT much longer. . An E22H-120/132 watt lamp is correct--and if you can replace just the bulb-(NOT hard at all to do) it will save you a LOT of money.

Periodically my 52HM95 would have some little electrical glitch where it would not come on when I turned the tv on. I would have to wait a little while before I tried again, or I could shut the power off...


I have a similar DLP TV. If you losing your new bulbs that quickly there is likely a problem with cooling. There is a fan that keeps bulb cool. Make sure the fan is working and there is nothing blocking the air passages. I have not had a problem with my fan but you should be able to find a replacement at Radio Shack or a computer/electronics store like MicroCenter. They come in standard sizes just make sure the voltage is correct typically 120 VAC or 12 VDC.
I have had the computer inside crash such that the sound would work, the bulb would come on, put no picture. Fixed by unplugging the TV for one minute then plug in and turn on.
The bulb repeatedly goes through its startup cycle but never comes on. It tries about ten times then stops. Fixed by removing the bulb housing and firmly tapping it on a counter top ten times. This was at Toshiba instructions over the phone and it actually worked.

After a period of time, vertical lines appear on the screen. Looks like jail bars. Sometimes turning the TV off, then back on will clear it. All channels. I replaced the projection bulb about 6 months...


no solution, same sounding problem though. last year we were getting lines through the screen and flickering and then the bulb burned out. had it replaced, 2 months later it did it again (they wouldn't stand behind the bulb so we had to buy a whole new one) this time had the bulb and ballast replaced because the repair guy said usually you have to replace both (why didn't they replace them both in the first place?) .. a year later and it's doing it again.. we get the flickering of the screen going on and off and horizontal lines that flicker across it. after turning the TV off and on a few times it seems to go away (or after it warms up)

i know know if i should order another bulb and ballast and spend the money for it to happen again or if it could be something else

let me know if you find a solution.. carolynspranger@gmail.com

Sony KDF-E55A20 shuts off for 30 seconds, then comes back on for 30 more


Do just as the others said pull out the bulb and clen the screens on top and bottom of bulb. BUT you can also prevent this from happening as soon the next time. You need to take off the back of your sony tv. On the right rear as you are looking at it there is a black blower on top that is on top of where your bulb fits in. you need a ninety degree phillups head screw driver. take the driver and take out the 3 screws... use a can of air to clean it out... You would not believe the holy hell dust stuck up in that blower!!!! Like I said, take the back of your tv off. If you are not sure where the bulb is once you get it off just turn it on. It's not going to hurt ya. If you are lazy about taking the blower off you can turn it on and shoot the can of air while the bulb is on but you are going to have to take the bulb out ALOT of times to get the dust out of the screens over and over until no more dust collects
