Astar 30" LTV 3001 ....These TV's have a cooling problem that causes premature electrolytic capacitor failure. De-solder and Test all the 2200uF-25v, 3300uF-35v and 1000uF-10v caps in the power supply (center board, back of TV). Use a good LCR meter that will read 3300uF or better, Replace all bad caps with 105c rated caps. If you don't have an LCR meter, replace all the mentioned caps on the PS. If fuse on board is blown, also replace the F9222L regulator IC chip. Mounting a small cooling fan on rear of TV over the PS will help keep your new caps from failing again. This requires holes in the stand bracket and the rear of the TV, power can be supplied from a 14V source near the bottom of the PS board.

have you tried checking the day time power saving settings to see if they have been incorrectly set

Your boot menu for Windows is corrupt. Try to boot from the windows installation disc and make sure to key any key when told to boot off the disc. Once the windows files load, you will have a choice of what to do next. If you have XP, choose the repair option and you will be faced with a black DOS screen...after the blinking cursor type
FIXBOOT hit enter
Try to boot the computer without the disc in it. If it does not boot, then boot off disc again and this time type:
FIXMBR hit yes and enter
Try once again to boot without the disc.
Also try to boot into safe mode by tapping F8 when you see the Compaq name come up during starting. If you can get to the multiple boot up option screen, scroll to "Safe mode with networking" and choose that. If it boots then you can go to the start button > accessories > system tools > system restore > choose a restore point back a day or two and follow the prompts.
If you have Vista, boot off the disc and choose start up repair. If that doesn't work, boot again and choose restore computer to an earlier time. Again choose a restore point back a few days. Good luck ParrotHead PC Repair

Hi,
The display drivers maybe corrupt.
Boot the machine into safe mode. Right click on My Computer (XP) Computer (Vista) and select manage from the sub menu.
When the window pops up select Device Manager.
A device list will populate. When it has look down the list for Display Adapters. Click on the + icon next to Display Adapters to it expands. Right click on the display adapter and select uninstall.
Restart the computer and let it boot in normal mode.
If it boots in normal mode let it detect the Display and install the drivers for it.
I would be a good idea to update the display drivers via the Dell support website.
If it still won't display in normal mode please post back.
Good luck.
