Question about Samsung DLP HL-P5663W 56" TV
The TV (model HS4676SX) was working fine then the dog stepped on the remote and now there is no picture or sound and the lights on the front are flashing like it is power cycling. If I unplug it then plug it back in it is off then when I hit the power button it starts the power up cycle, the welcome notes chime then it never comes ready with a picture and sound and seems to power cycle off then on again.
Is there a way to reset to factory defaults? I have unplugged it but that did not reset the TV.

SOURCE: dlp tv will not "fire up"
Hi there, your instruction manual should have a trouble shooting section, and will tell you what various warning lights are indicating (ie the Lamp/Temp lights will flash in a particular sequence), and will give you the probable cause. In some cases, it could be blocked vents (dust causing overheating/shutdown), or just the lamp failure or faulty switch (indicating loose cover).

This is a possible fault in the power supply, and can be a problem with some decoupler caps on some of the boards. The vertical bars and unstability are usually attributed to having high frequency noise and or clocking pulses crosstalking on to the power distribution lines that run through the boards. This can be switching power supply noise, or cross-talk from clocking pulses.
Another thing that can cause your described fault is unstable clocking between the devices that are reading and writing to the data busses. There are a number of data busses running through the set for the boards to be able to communicate with each other.
The tech will use the process of board swapping to service the set, and then do the adjustments as necessary to make sure the new boards match up.
Yes... DLP sets are fairly expensive to service!
This is my personal opinion. If the set is out of warranty, I would change for a Plasma or LCD set. If you compare the performance of these to ther DLP, the difference is very big. From what I am seeing from a service point of view, the DLP's are lower in reliability.

make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast.
Call a local tv repair shop to further diagnose the problem.

Did you set the lamp timer? Did you replacement the lamp w/ the original or an OEM, OSRAM? make sure the closure of your tv is all the way in.
