Mitsubishi WD-62525 DLP - adjusting low-level grey

I recently reapired two WD-62525 DLP's by replacing most of the caps on four boards. In the service menu, I can adjust the hi-level color drivers (GGH, GBH, GRH), but the settings won't budge for the medium and low-level colors. Shadows are green. This is most prevalent using a cable box with the HDMI port. However, using the component jacks instead, the contrast is beter, the colors look good, but I see rolling red lines in the picture - on both sets.
Any way to adjust the low-level color drivers?
Or, get rid of the red rolling lines?
Thanks,
Dan

My Mitsubishi WD-62525 wont even turn on. No blinking lights or anything. Power Board bad???


I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices. Here are some options for you. 1. Have it fixed by a professional 2. Open your TV and find PSB. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
I have a tip/tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It'scalled: Fixing the Philips Turns/shuts off on its own problem. Hope this helps and Good luck.Kaufman605

Best settings for moderate to low light viewing?


Using your remote, click the "video" button (mid area, Right hand side) and adjust the brightness, contrast, etc., to your liking. Only you know what you like. If your picture can be "plenty bright enough"...then just make the necessary adjusts to whatever looks best to you. If your picture is "very dim" no matter what the video settings are, you need a complete cleaning of all lens, mirrors, and screen...and possibly a new lamp.

Here is the picture for a Mitsu62525 power board, which is similar.

You recognise it because you get power cables innesting into the power board.

If you decide to work on your TV, get the service manual first.
