HL-S5687W looses picture and sound after heating up. When I change the channel, the picture returns. The fan is not coming on.


This does not but does in one way make some sense(I had to read your question a few times).

The key here is the fan does not turn on-----If any of the fans (lamp or others to a lesser degree do not come on: The lamp fan must come on or in a short amount of time--it should turn the set off and some have a lamp light and a temp light----

The set monitors the temperature of the lamp especially when set is turned off---it will not turn the lamp off until it cools to a specific temperature is reached----hence if set on for while and just unplugged which will kill the power to the lamp fan the lamp or even ballast that drives the lamp can be damaged.

Voltage to the fan can be measured and it must come on when set is powered up-----issue could be either fan is bad or no voltage is reaching it===most 2 wire fans will have the voltage marked on them--24vdc equals 24 volts Direct Current etc.

If a fan NEVER COMES ON (especially the large lamp fan) sooner or later something is going to get melted or fry.

Your description is a very good one but the issue is a bit rare (fan dead).

I would if there first check for voltage at the fan when set is turned on---if its there but fan not running the fan is bad.

Seen a few where dirt on the fan or even moving the fan blades made the fan kick on but by then you KNOW it is bad.

Let me know if you have questions or what you find.

Comp 2 showing instead of video 2 - Picture in Picture


Depending on model number try first to UNPLUG set and turn on again.

Please confirm model number if possible so I can assist.

I AM GETTING A MESSAGE ON MY SCREEN TELLING ME TO CHECK(FAN NO.2)


New TVs have fans to help cool their circuitry. Sounds like your fan #2 is bad. Remove the back which means removeing all the screws around the perimeter as well as in the middle and don't forget the ones in the small signal area. When the back is off you should be able to see the problem, aka, lots of dirt around the fans. Move the unit to the outdoors and using an air hose blow all the dirt out of the unit.

Once this is done you should go to http://www.encompass.com and put in your model number. Do a search for a fan. If you believe that this is the part you need order it. I suspect that all the fans are the same.

Remove and replace fan number two and you should be able to reinstall the unit. Let me know if you need more help.

Thanks for using FixYa and for the generous rating.

Vacuum out all the dust.

There are 2 small red lamp. One indicates HEAT problem. The other one is the LAMP indicator.

Screen went black


Remove the front grey bottom panel of you TV (don't forget the 2 screws behind the front AV cover located just below the power button) then remove the panel behind the grey panel. You should see 2 heat sinks on the front right of your TV, place a fan near your TV and have it blowing on the heat sinks. Now turn on your TV and see if it stays on longer then it has been. If it does, your DC amps might be overheating. If they are, you might be able to fix your problem by adding in a little more heat sink compound between your DC amps and the heat sink itself. You can find the compound at Radio Shack for about $5. let me know if pointing a fan directly on the heat sinks helps.

I have a teac plh4220sd and is about 18 months old. recently the picture quality started to degrade and yesterday completle lost picture but still have sound, is there anything that can be done


Hi I have the same problem and fixed it by running a fan behind the TV I think the Plasma screen runs to hot.
The fan completely fixed the screen if you feel the top of the TV you can see how hot it gets running a fan behind the set keeps it cool.

Extremely loud fan...shaky picture


I would suggest to replace the fun to keep the light running cooler, the reason you loose the video after a period of time is because the fun is not providing enough cooling.
If the fun is noise it means the bearings inside of it are not working well anymore.
Let me know if you need more help.
