SOURCE: My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

This is very possibly a power surge, can you tell me how many times the light blinks, you probably have a bad power board now if you had a power surge.

I have an RCA Scenium HD DLP 50" TV Rear


What is the Model Number that is printed on back of TV?
You say TV is DLP ,but you are posting Model# HD52W59 that is for Projection that has 3 Tubes Red/Green/Blue Tubes.
If TV is DLP then problem will be the Color Wheel
If it is Projection then it has a coil on the deflection board that either needs to be replaced or
resolder ciol and take a Glue gun and glue over the top of coil. Coil LL037 on the right handside of the FBT flyback transfomer.

There are capacitors on the power supply board that dry out with age. You can identify them by observing the tops of each of them. They have to be flat, not domed. Some of them may be discolored from heat. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

My 50 Viore dlp tv turns itself off after just a


HI, this may be a simple cooling issue. try inspecting the cooling fans that are located near the power sector. if these cooling devices are not operational, they will cause the power board to shut down periodically, due to heat build up.

If the fans are operational, this will confirm a weak and defective power power board.
