I turned on my 1209s and it was working about 15-25 mins. and then there is no picture on screen. The 1209s was still running but no picture or light out put from all R, G, B tubes.

After turned off 1 night, I turned it on in the morning and 1209s was working for 20 mins and then no light out put/no picture again.

What is the problem? How can I check the cause of the problem?

Thanks a bunch.

Any red lights?

No light from Red Tube. Fans are still running.

Thanks

I meant red LEDs. At the back or front of the PJ. Or at PS. Or any cards.

Check for red lights on the G2 and the EHT board. I'll bet the set is going into HV shutdown mode. For a layout of the 1209s, check the 'tips' section of my site below.

Where in the world are you ???

Dont panic there are spares available for these fantastic machines.

Thanks for all answers. I checked and found only green light on G2 and EHT board.

Here is more info. I found.
When "No picture" found, I turned off my 1209s and waited about 1-2 mins. and then turned on. I found that my 1209s was working again and no sign of any problem. I tried turned off and turned on 2 - 3 times and it's always work.

What should I do next?

Send me the quadrupler and EHT board. I can test/repair them. THe EHT board has no green lights on it, you know that, right?

For me this problem was SMPS-module, wich was defective. A quick swap and never p problem again!

send me a pm on jrhemmabio@hotmail.com
