I have a Samsung rear projection tv, the picture is faded and the colors are not crisp or clean cannot watch it like this what do you think the problem is?


If this is a CRT-type rear-projection TV, the CRT coolant fluid is probably broken down. It's supposed to be clear, but after a long period of TV operation, it turns a yellow-brown color. If you unplug the TV and remove the back, you can look into the tops of the three picture tubes. They should be a clear red, green or blue color, with no yellow-brown tint.

CRT coolant can be changed, but you need to be very good at mechanical work to do it. Besides the safety considerations (picture tubes and other parts may carry a high voltage charge even when the set is unplugged), spilling broken-down coolant on electronics is usually disastrous, so you have to be very careful.

LCD panels used in projector applications may lose contrast if they are overheated (this can be caused by failure to keep the vents clean as recommended in the owner's manual).

You would have to provide your set's model number to get more specific information.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

HCM4215W 42 in. Rear Projection Television


When the screen goes blank, hit any remote function that will show up on the screen-like volume bar. If the display is missing as well, then you have a tv problem. If the volume display is there when the tv picture is not, you may require a software upgrade.

Vertical lines


The red line in the crt is the sreen voltage is to high or bad tube.
A simple fix is if you take off the front panel there will be a black box be careful it is high voltage make sure you are a pro.
there will be six controls look for the one marked screen and is for red tube adjust very slightly counter clockwise.until red
line gos away. If that does not fix it its the red tube.


I hope this helps doctor video
