All three lights on but NOT blinking
Posted: Thu Jul 09, 2009 4:16 am
Hello everybody, I'm new here and did search the archives first for my problem with no luck. I learned some valuable info but not enough to diagnosis my problem.
I have a HL-R6167W that started acting up about a week ago. It started by not responding to the remote or side TV buttons after being on for say 20 minutes or so. It was also taking longer and longer for the lamp to start up and show the picture. Although I know you're not suppose to, I started unplugging it from the outlet to turn it off since it would not respond to remote or the buttons on side of the tv. After about 30 minutes it would "reset" or something and would turn on after being plugged back in, I could watch it for hrs but it would just stop responding to TV remote commands and buttons, as I said previously.
Then after few times of using the plug in and out method, all three lights on the front would light up BUT NOT BLINK. I bought the TV it in 05 and had never replaced the bulb so figured it couldn't hurt to do so and started there. Got the bulb today (a phillips from DM) and replaced it but all three lights are still on but not blinking. They will stay lit as long as the set is plugged in but I can no longer get the TV to turn on or access any of the menus, etc...
So I opened it up further today to get more info and none of the fans are running while plugged in with the three solid lights on. I hear one soft click but it does not appear or sound to be coming from the ballast. Sounds like it coming from the left side when viewed from behind (side opposite the power supply and ballast).
I did disconnect the blue and brown leads going to the ballast and used a voltmeter and got essentially no Volts DC (maybe .03-.5 Vdc). I tested the power supply further by reading the board and testing where the multi white and grey leads connect. I only got the 33Vdc and 5 Vdc readings from "top" connector with the two prongs per line, none of the ones that indicated 12Vdc put out anything. I also tested the "bottom" connector with the single prongs and got 5 Vdc, 12 Vdc & 33 Vdc readings as indicated. I hope this is clear to someone (I'm a mechanical engineer who failed his electrical courses miserably in college).
Is is possible only the low voltage is working and not the high voltage (320-380 Vdc) from the power supply? Or are there some other permissible required before the high voltage is passed to the ballast?
Please help! I have a party already planned this weekend to watch UFC 100 and it doesn't look good!
Thank you.
