Question about Toshiba Replacement Lamp/bulb For 72cm9ua, W/housing, 150days Warranty

Open Question

I have a Toshiba 72CM9UA DLP TV. The picture has developed many horizontal lines that move about and areas of picture will loose definition and pixilate with blobs of single colour. I changed the bulb a year ago when that failed. Any ideas what the cause is.

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

SOURCE: Toshiba 52HMX95 DLP has weird gray think line

DLP TVs work projecting light throught a tube covered with mirrors, called the light tunnel.

The gray shadow it is something in the middle of the light tunnel, probably a mirror that has gone out of place when you moved the TV.

Picture is wavy and has black vertical and horizontal band


The following are supposed to be checked on the horizontal and vertical,

eletrolitic capacitors near a line transformer
zener diodes

36 Inch Toshiba - Single Bright Horizontal Line


You're losing your horizontal voltage that drives the fly back transformer. Poking around inside can be hazardous to your health since you have to worry about high voltages present on the picture tube even when the TV is off. You may still be able to get parts for those old TV's but they may hard to find. You can try here, but if you have no background in TV repair, it will be pointless.
