20 Most Recent Mitsubishi WD-60638 DLP TV Questions & Answers

If you tried a cheap bulb then that might be the problem as some of the bulb carrage may not be complete4lyto spec. I had one that was close but there was a gap between bulb and where it fits. I went with a bulb dealer that had I believe a 1 year warrante and I have had no problems. I had a 73838 tv set.

if its a dlp tv most likely the dots are from.the bulb if its an lcd tv your screen may not be of high quality u need to change it

You have a bad connector in the lamp. Stop running the TV immediately and contact the company you purchased the lamp from. this is common in older DLP tvs but not in one 5 years old unless you have a lot of hours on it. the connector can crack and arc inside the plug and then melt and smell terrible. It usually very repairable if you can get a ballast for it. the plug is part of the ballast.

Sounds like its lamp inverter board too is faulty. Replace it. It is a good practice that the inverter board and lamp should replace at one time.

Make sure software was in top menu in USB stick. Not ib a folder. Try reset buttons on front of TV. Could be bad e2p module. (boot firmware.)

Maybe a power regulatr card issue?

Never really had that issue the one I worked on Operated normally for 20 minutes and then shut down completely. The fix for that is to get the OEM bulb instead of the replacement

DLPs are a old technology. If could be the bulb or the spinning mirror. Cheaper to get a new flatscreen TV that to fix.

If you get one that has the correct airflow and RPM along with the proper voltage and such, but I would try on Ebay first.

Likely a bad bulb.
