    Boonys - Can you post a picture of the location of the 14V source you reference? That would be most helpful.

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.

I have a black screen that says safe mode, safe mode with networkin , safe mode with command prompt and laast known good configuration but when i go to safe mode my computer just reboot all over again


This recycling/rebooting into this screen is normally caused an error (hardware or software).
You MUST turn off - Automatic Restart to see the error message.
Power down your laptop.
Press the power button to turn-on laptop.
Start pressing the F8 key immediately AFTER the DELL logo screen and BEFORE the windows screen.
You SHOULD be brought to the same screen as you described above but with an additional option: TURN-OFF automatic restart. Select this option and press ENTER.
Let laptop cycle and you should see blue background screen with white letters giving you information.

Please provide the ERROR message on screen BEFORE we can advise you any further.

Hi, I have a Westinghouse 42"


The only other thing that I would think to replace on this is the power board. You may have bad power going to the main board. Other than that you may be at the point of no return on that TV.

Screen not working


The backlight or power supply for it has failed. Use a strong light next to the screen and look for a faint picture. If it is out of warranty, take it to a repair shop.

Jensen LCD JE1907DC keeps looping the Jensen intro logo.


I don't have a solution but do have the same problem.
I took it in a reputable shop and they told me the main board was gone and they could not get parts for it.
I just found out that Jensen is a Audiovox trademark.
