Re: HL-S5687 DLp tv
Your keeping a part that is warming up and shuts down your shutdown that protects the tv from burning up... cooler... to find this you might need a hair dryer or a can of freeze mist.
I believe the left side is your high-voltage section.
you can also let it warm-up without the fan .. let it shut down and feel parts with set unplugged to see what is running hot.

Light engine assembly has to be removed. This involves unplugging various connectors between processing/control chassis on the left side and engine assembly on the right side. Mounting screws on the top and bottom of engine assembly. Then remove light engine assembly completely from the TV. Fan#2 is the lamp cooling fan and is located beside the lamp assembly.
It is not too complicated if you draw a picture of where all the plugs are removed from. If one plug is not put back correctly, unit will not work. Usually a tight fight sliding out the engine. Plastic cable tie-down between the 2 assemblies can be cut and discarded, this makes re-installing light engine considerably easier.
Cheat the cabinet safety switch with tape or stretch connecting wire across it to hold it in "on" position for test after reassembly.
Service cost may be $150-$200 if you don't do it yourself. We do it in most Canada cities.
Look for the computer processor inside the TV. It needs to be cleaned. A can of compressed air will work. The processor is overheating and causing the tv to shut off. Look for the small fan that is supposed to keep the processor cool then remove the dust.
Don't recommend replacing the light tunnel if you never had any experience with DLP optical systems. you need to pay careful attention to the way you remove any screws or you will be forced disassembling the engine multiple time to get the alignment correctly.
