Ballast advice needed RCA M50WH92S

Postby drdreww » Thu Oct 28, 2010 10:12 pm

Cant find any clear answers anywhere on the internet.
some say the ballast should click/snap some say it is bad because it does.

So I just got this TV off of craigslist and it worked fine for a week. then it started having the RCA 5blinks of death. so i vacuumed and canned air it all out hoping it might get better with better airflow. it started working again for a week then started again. the tv comes on just fine, then after seemingly random increments of time (35 - 50 seconds) the bulb would turn off but the sound would stay on, 5 blinks of the power light then come on again. have been doing alot of research and from other peoples problems i concurred that it is probably the ballast. i could hear it audibly snapping/clicking before the bulb would turn on.




has anyone dealt with this before?
should i try a lamp before anything else? is there anyway to test the ballast/lamp/powersupply ?
picture is bright and clear when it is on.
thanks for your help guys!

Sounds like the lamp is going bad. These lamps last approx. 5000hrs. which is equivalent to about 2yrs of normal use time. If you can contact the seller and find out the last time the lamp was replaced then you
may have your answer here.
Good luck with your repair!
