Toshiba 62hm84 dlp

I replaced the bulb on my tv 3 months ago. The tv worked fine for a few months then it stopped working. When I turn the tv on it doesn't have a picture but sound. The red light stays on but the green light flashes around 10 times. During the time the green lights flashes the fan turns on and the bulb lights up. The tv turns off then turns back on several times before turning itself off.

Sounds as though the system may have overheated. Do you regularly check the filters and clean them? An airduster can also help to blow dust out of hard to reach places.

SOURCE: replaced bulb. Worked for a while then wouldnt power up again.

the cheew cheew cheew is the colorwheel not spinning properly. either the colorwheel motor is shot, the sensor can't sense it, or the power to it is too low. first thing: remove the cover and blow the dust out of it with canned air. dust does a lot of damage to these. if it is the sensor, cleaning it off might help. if it is the colorwheel, i have bad news: on the x1, the colorwheel is not sold seperately from the optical engine. you'd have to get the entire optical engine. now the worse news: infocus no longer makes or sells parts for the x1. you could try and find one on ebay that has a different problem and swap out the parts

SOURCE: HELP! I changed the bulb already. My NEC VT 470

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.

Changed my bulb on my toshiba dlp 62hm84 andd it's still not working, no picture but have sound


Most likely you have a bad capacitor on the power supply board.
I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV(warranty was expired ofcourse) and found four bulged capacitors. Many electronic companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices. Bad capacitors can cause the problem you are having.
Here are some options . 1. 1.Have it fixed by a professional 2. 2.Dig into your TV, find PSB, Check for faultycaps. If you find some(bulged orleaking) bad caps replace the entire board 3. 3.Remove and then replace individual faultycaps. This takes some solderingskill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
Hope this helps

I have had the same problem and after several trips to the shop I realised it was caused by humidity. The shop was air conditioned so the problem never happens there. A dehumidifier or air conditioner "solved" the problem.

You will find that when the old lamp exploded, either it damaged the ballast unit or there are shards of glass stopping the cooling fan.
