Hello all,

This looks to be the best forum to ask for good advice.

I have a Samsung HLP5674, it has basically been error free since (2004) until the last year or so.
Not even a lamp needed replacing though I estimate the DLP had 8000+ hours on it.
As a side note, in the last year, I may have seen (5 or so) signal lockup errors that I attributed to the input source,
that MAY have actually been on the TV side.

Today the HLP5674 is totally dead.
No response to the power button or remote control, no display at all.
Because of its age (and I know everyone will say it is due), I replaced the lamp with a new Phillips.

So now, Lamp replaced, still exact same no power no response to the power button, no spinning no balast clicking.
>>>I can force it to click, fire the lamp and briefly spin the color wheel, by a power-plug boot only.
But after that still the same, nothing.

Checked the balast INPUT voltage and it is very LOW:
on power button ON it only will go up to a max of 180v
and then slowly bleed off back down to 20v or so.

This is far below the 320v suggested by ovadoggvo
I think I have a basic power problem but I am unsure the likely origin, help??
What to replace next??
I have my spare bulb already

eef,

Ovadoggvo seems to be the resident expert here, but what I can tell you is to check the lamp code it's familar simple:

With the TV off, press:

MUTE, then quickly followed by 1 8 2 and then the POWER button. After a few seconds, it should take you to the options menu (or the service menu, different firmwares act differently). Find the "OPTION" option, then click the right cursor button to pick it. This will take you to the lamp counter reset menu. You can view the hours and/or reset it. When, and I'm sure it's only a matter of time, WHEN you do get your TV up and running with the help of this forum, please post your results

Hi WesternDigital!
Thx, but my problem is so low level, (nothing responds)
no display
so I cant use lamp codes etc.

Help anyone?

rrf,
I just saw your post. To me it seems very likely that your Digital Board is bad. Now remember.. the digital board is not the DMD board. The digital board is the board with the DNIe chip on it. It normally has an L shape with your digital tuner on it.

From my experience, the Digital Board would be my first guess....


I would check Discount-Merchant to see if you can pick one up at a resonable price.. Otherwise, samsung want's an arm and a leg for one!

Let us know how it goes.
