Question about Televison & Video
Hello Jamie Florence,
First best guess... Power Board:
While I dearly love to tell folks there are really only two (large)
circuit boards in most modern "FLAT PANELS"...
That is NOT actually the (whole) truth is there are several...
The least of which is your power CONTROL , which
includes your IR receiver (typically) together with
your SET resident controls... (On, Off, Volume, et al).
Just to assure yourself the "problem" is
INTERNAL you should tape off your IR receiver...
Your owners manual PROBABLY discusses moving your set out of DIRECT SUN... and taking precautions to afford reliable operation (could also be your REMOTE) ... Putting on the TAPE will prove it into the SET.
Always check your OWN BOARD NUMBERS...!!!
Never force any connections...!!
Take lots of pictures ... put EVERYTHING EXACTLY BACK.
My first and ALWAYS recommendation... always protect delicate SEMI-CONDUCTORS by wearing anti-static wrist straps... A tiny static spark you might not feel is sufficient to RUIN the diodes in your cars ALTERNATOR (honest... for reals).
Second serious precaution... Use shopjimmy, amazon, eBay or worse... Searspartsdirect.com... (at page bottom)
Never rely on anything but your OWN circuit board numbers.
Serious ELECTRONIC technicians always take STATIC PRECAUTIONS... and turn off the power (when-ever possible).
It is not improbable that another board is your issue...
but compared to a "QUALIFIED" (good) home repair technician...
It is a mistake you can afford about 5 more times...
and if you can go BACK to your ORIGINAL FAILURE condition... you are doing fine (excellent start)...
Most "home technicians" aren't even good.
As far as I'm concerned... these packs are too cheap to recommend live power tests (YOU can get seriously ZAPPED)...
If the SET does not immediately power up... I would suggest you assume 1 (one) of two (2) things...
1. Your "NEW" board is also bad (or you did not try to select "sources" when you installed it... (been there.. did that).
2. It was actually your MAIN-BOARD that needed to be replaced.
Buy one.... TRY IT.
Hey... if you like the set... so you end up with a couple of spare packs... properly handled & stored they will only appreciate in value).
Ill-advised activity... (voltage testing)...
It is SAID... WHAT does not kill you makes you stronger...
(I recommend WEAK: these packs are inexpensive
(Not worth ANY RISK)).
If you own a decent volt meter...
and you can look CLOSELY at the TEST POINTS... YOUR POWER BOARD voltages are printed on the circuit-board OUTPUTS:
Just keep in mind... you can get hurt... while causing more damage... with careless handling!!
Take photos... Work safely... Check your numbers and
ALWAYS wear ESD (static) wrist bands...
Hope this helps!!
