Question about Toshiba 42H81 42" Rear Projection Television

Open Question

My Toshiba 52" TV stopped working - no picture or sound; similar to what i did 2 years ago when i experienced the same problem, i purchased and replaced the lamp unit (Type: TB25-LMP S/N: 23311083A; Rated: 120W DC50-120V). Still, no picture or sound even though i replaced the lamp unit; instead, it makes clicking noise as if it is going to turn on and shuts off repeatedly. TV Model #52HM84 Serial # 20734664

SOURCE: I have replaced my lamp unit TB25-LMP but the red

Unplug the TV, ensure the lamp door is installed and the screw is snug. Plug the TV in and wait a moment. touch and hold your finger on the power button on the front of the TV. If your TV does not power up, your ballast and power supply should be suspect. Many Toshiba DLP sets use a similar lamp design. They have been known to burst and cause a momentary short. This can knock out the power circuits which feed the lamp. If this is the case, post back for further details if you wish to repair this yourself. I hope this was of some assistance.

Toshiba regza 32hl67 losing its' picture and motion is slow


I have a toshiba regza 32hl67 LCD tv which is only 2 1/2 years old. The picture on this unit just started to go the other day (screen darkens but images are still visible and the motion/movement is very slow). I contacted Toshiba and they just said to unplug the tv for 3 minutes to reset the tv. This doesnt work. I am VERY upset with Toshiba, after paying $800 for a tv that only lasted 2 1/2 years. If anyone has had similar issues and know how to fix it, please let me know. Thanks

This is a vertical circuit problem that is either bad connections on the vertical IC or a defective IC. If you can solder, you can fix this yourself. Look for a small flat IC attached to a heatsink with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC. There may be defective caps in the circuit as well, but those don't usually cause complete vertical failure. If the picture does not return fully, update this and we'll continue on to the next step.
