20 Most Recent Proscan PLDED3257A 32" LED TV 60 Hz, HDTV Questions & Answers


Hello John West,

I just checked MY first recommended SPARES dealer
(link will be at bottom: "SHOPJIMMY" for stock... on your
ProScan plded3257a-b... They are out-of-stock

WHICH MEANS MY 1st GUESS is a popular GUESS.

Your main POWERBOARD is divided into specific power sections... MOST LIKELY... you could open your set and (I DO NOT recommend) be able to measure... the PRINTED voltages around the out-put points WRITTEN around ON the Printed Circuit Board... (but these boards are in-expensive and the risk of injury is not worth the POTENTIAL savings
(assuming you have the requisite skills & materials).

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 the mainboard 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 POWER BOARD 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)

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...

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Check out the inverter board for a blacked out screen.

Fault with the control voltage at its amp section. May be a system control IC fault too. Contact any service tech: to make it confirm, and to get repaired.
This is not an easy repair work to do for a customer.
