RCA DLP with New Bulb still not working?
ByWe have an RCA DLP tv for 4 years and we replaced the bulb. It still won’t work and still acts like the bulb is bad. How can we determine what else it might be wrong and fix it?

Turn it on…
Listen carefully for
1] The fans to start…
2] The color wheel to come alive
3] The lamp power supply to STRIKE the lamp
4] The lamp power supply to RUN the lamp
At that point your lamp is lit, and THEN the picture and sound become active…..
That’s the startup sequence, and it must have 1 before 2 or 3 occurs…..

On board fuse (F1) They can blow if the the brightness is to high. Use an ohm meter should 0 ohms Check the leads shorted together.

You should know that a fixed appliance can’t be like the first day it was!
Companies usually specify their product’s lifetime by the grantee time they will accept.
I’m sure that the grantee time of your TV has been finished after 4 years right?, So why don’t you buy a new one?
RCT TV are cheaper in the market right, Because of LCD and Plasma.
So I don’t think if buying a new one is going to cost for you, because they money you pay for a new one is going to be less than the money you want to pay to repair the old one Again !!!
Hope it helps!
