Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

i had the same problem of starting the car and it dies, it turned to be the transponder not sending enough signal to the cluster. this may require a new transponder and re programing of such.

It sounds like something else may be causing an issue. Since so many replacements have been made, but the problem persists I would recommend getting a technician out to look at the problem to make sure everything else is fine.

Only a few things could make the picture freeze and shut down. I would recommend checking the DVI cable that goes between the Chassis and Optical Block to make sure it is secure and tight. If it is (and it probably is), most likely it is the Optical Block causing the problem.Because of the cost involved, I would have a Professional to come out and diagnose it to be sure.
I hope this helps,

No running the laptop without a battery will not hurt it in any way. I would suggest like you thought that it's a cooling problem. It may need the cooling fins cleaned out and silicone grease reapply'd to the processor and heatsinks.

Sounds like it is getting to hot
Check how hot it is after one hour then check it after the image goes egg see if it is getting hotter.
Also make shore nothing is blocking the air vents.
Could also be a fuse on its way out.

the problem is in the verticle section, if you are a technician check a verticle IC and a capacitor of that stage. to allocate a verticle stage follow 4 cables coming down from deflection coils, two of these wires goes near transformer, this is horizotal and the other two goes near an IC this is verticle. positive idea.

my guess is convergance ic but to troubleshoot it the best soultion might be to get a can of freeze and spay it on the IC while the problem is happening and or tap the board/ic's to see if you have a loose connection,

Does it feel like it's running hot? If so, check that the cooling vents are clean and that the fan is running. A second thought is that you may have some mal-ware that you've picked up off of the internet. I fought a similar problem on an IBM T41 for several weeks. Look up and download a copy of Ad-Aware SE (it's free!) I wouldn't have a computer without it installed. Picks up all kinds of crap that Norton never even sees. Same to be said about AVG, and that's free, too.
If this tips don't solve your issue, get back to me and we'll pick up from here.
