Replace the terminal pcb part # DUNTKB128DE03 you may be having a short in the secondary power supply. you can get the manual here https://www.vancebaldwin.com/shop/research_new/SHA/LC20B2UA.pdf to help you better trace the short. it can also be the main board too better to chase the problem than to make guesses.

I havd a Dell Dimension 8200 that sometimes shuts down and power light turns yellow. I can usally open case and plug and on plug to get it to power back up. Recently replaced fans due to fan failure....


Thank for the detail, it really helps...
Most people forget about the power supply. If the power supply overheats, it will shutdown. When shutdown, it will cool off then operate again.

A power supply goes by WATT ratings, the average size power supply is now 450 watts for an average system and should cost around $60.

good luck and don't forget to vote.

My Stilletto 10 doesn't reliably record programmed talk shows. I leave it on and plugged into my car kit (yes, it is powered by a plug that stays on when the car is off) and when I come back it is...


Is it set for auto shut down? It took me months to properly record with this thing, frustrating at best. Now it's almost flawless. Go in to menu then settings then dock. In that menu you will see "Auto Shutdown". If this is on, your receiver will shut off after 4 hours only when plugged into the car dock. When on a home dock it will stay on. Turn this off and it will stay on until you shut down. Auto shutdown is the default setting. If for some reason you receiver is reset, you will need to check this setting again, because it will turn auto shutdown on again. Hope this helps.

TV goes off intermittently


sounds like an intermittent shut down which is heat related. some part , maybe one stuck on a heatsink is warming up and running too much current triggering shutdown.
to find it you can tell what is shutting down with a voltmeter, or you can heat suspected parts with a blow dryer to speed the shutdown .. or freeze spray to see if it goes beyond your shutdown time.

Fuse F3701 is blow-up after few munites turns on. If replace a fuse F3701 again, it work, but the set turns of any time, check the set: Fuse F3701 is blow again?


Look at the power board " the one with the fuse" for capacitors that look puffed at the top or leaking at the bottom. If these are leaky the voltage drop will cause the current to rise and pop the fuse. After a time the caps will get bad enough that the set will stop working and may cause more problems.

Always shutdown my IBM ThinkPad A21m 2628 PC Notebook


It must be a processor overheating problem, check the vents are not restricted and if the fan is always on or never comes on because of a faulty temp setting then theres a overheating problem and the processor will shut down before any damage.
