SOURCE: Flickering blue picture

I finally got around to dismantling the TV. This is no mean task. The chassis is tethered to the rest of the set my over a dozen wiring harnesses and a few of these cannot be disconnected near the chassis but instead require removing the “right support” near the air duct and taking the shield off the lamp ballast. Once the chassis assembly is out, it is a further significant task to disassemble it to get at the various PWBs (POWER, FMT and DM) having the suspect caps. I’m sure reassembling everything will be a fun job!

I have not yet had a chance to fix and reassemble but I wanted to post this no as I’m not sure when I will get around to it.

I did find six of the fourteen known-problem caps to be visibly bulging -- both 3300s and two of the four 1000s on the PWR PWB plus two of the four 1000s on the FMT PWB (see photos below). Ironically of the four 1000s on the DM PWB, which I have heard are the most common to go bad, were bulging and I considered skipping these as the DM it is the toughest board to extricate from the chassis, however I figured I had come this far and I would just as soon replace all twelve 1000 uFs as the parts cost $0.23 and I really never want to have to do this again.

If I had to bet, the two 10V 3300uF caps on POWER board, which were actually leaking black goo, are the actual culprits, but with four of the 1000 uFs also bulging it is probable only a matter of time until they failed as well.

Here is the POWER PWB with the known-problem caps (C9A37, C9A38, C9A51, C9A52, C9A61 and C9A62) highlighted:

here's the FMT PWB with the known-problem caps (C8F19, C8F21, C8F22 and C8F27) highlighted:

and the DM PWB with the known-problem caps (C81A2, C81A3, C81B3 and C81B4) highlighted:

those are going to be dust spots on the LCD panels internal to the optical engine. i suggest that you take the screen off and take off the panel i nthe middle of the tv with 2 screws in it and there will be an area that has 3 metal fins covering thin orange ribbon cables. the 3 square objects at the end of those ribbon cables will be the LCD panels spray wiht air compressor unitl clean and that should greatly help your problem.

Remote missing on old dominator garage door opener


This is the most complicated way I know of coding a remote and I am a tech. who does this all the time.
Turn power off. Wait 3 sec's & turn back on. Quickly press program button on back of box twice. Lights will flash, bottom light will stay on. Press program button twice, & No. 3 light will start flashing. Press and hold your remote button until light stops flashing. Code will be accepted.

Hi jezzwhizz

You'll see that at the back of your Projector there is 2 VGA ports 1 in (normally blue) and 1 out ( normally grey ).

You are most probably using the grey one , switch it to blue.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
