Hey gessneruk, remember the one you and I were working on saturday that had no +24V? I got it up and running!

I had lost +24V on my power supply (Megmeet MLT386) and found F2 on the power supply blown out (3.15A). This was caused by a shorted QA2/QA2A (both are 9N50C FET transistors) After replacing these it still did not work, I found that four .47 ohm SMT resistors at R233 through R236 were blown open, I replaced them with a single .1 ohm 2W resisitor, I also had to replaced transistor QF1 (marked 2X4). After replacing all of these components, I restored the +24VDC and the tv.

    Oh, I forgot to add I had also found that diode DS2 was shorted, this is an HER207, just to be safe I replaced diode DS1 although it was not shorted.

I have an element ELCP 0371 lcd tv and the picture goes black intermittently


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

TV won't power on, repeating doulbe red light blink


Question Television is not working, screen is black, blinking red led.
Answer Television is probably malfunctioning due to electrostatic discharge. Try resetting the television by unplugging it from the power outlet for 10 seconds.
  1. Make sure that the power cable on the display and the VGA cable with trailing audio cables are connected correctly (use the originally supplied VGA cable.) between 'MONITOR' of the TV and 'VGA1' of the display.
  2. Make sure that the display is switched on.

Scott LCD won't turn on with remote or with on button


Do not shut off the TV. Put cardboard in front of screen when not watching.
MY THEORY
The power serge when the TV is turned on puts a stress on the caps (ac to dc volts) .
Continued off -on weakens the caps until failure.

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
Well I think that if you would have a service manual for this set that would help a lot, I can send it to anyone who wants it via email/gmail. Let me know if anyone want one.

I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif

And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.
