When trying to adjust contrast, setting jumps from 42 to 58


oK, I will tell you what Philips told me some years ago about this set and others made at that time.

You have any unusual problem, remote does not work, sound goes out or up and down, etc etc it is the small signal module.

The set has a small signal board (from back it is large board on far left) and the small signal module plugs into it. SSM is about 4 by 5 inches and all surface mounted parts.

The board will have a part number on a label on it.

EVERYTHING is routed thru this board from either the remote or the front control board.

They may still be available on an exchange basis from someone like PTS ELECTRONICS but were over 100 the last time I looked a few years ago.

95% chance your problem is that board.

GOOGLE THE MODEL NUMBER AND ssm OR SMALL SIGNAL MODULE FOR MORE INFORMATION.

REGARDS, sd tech

Ic location


they are located in the front of the TV behind the speaker grille. Remove the screws from behind that secure the speaker grille and the two inside the small door below the control buttons, Then you will see a small access panel remove that and the ICs are on the skinny board up front. Do not remove the rear panel on your model with the cord plugged in or it will destroy the HD circuits

Shakey screen


Needs to have the hyper module repaired... There are a group of caps on the hyper that need to be replaced... The hyper module is a stand-up board on the left looking in the back of the unit just behind the jack panel... Need to remove it and send in in for rebuild or attempt the repair yourself..

Kevin,
I'll send over the link for the manual to your personal addy but it won't be much help I'm afraid with identifying and removeing the hyper module. The hyper module in that unit is a square metal can standing vertical on the signal board just behind the jack panel - - leaft side looking into the back of the TV...
Screw driver and some real patience and it should be no problem to remove. From there send the module in and have it repaired and you'll be glad you did...

The Hyper Module Is Defective / It Is Located Behind The Jack Panel On The Signal Board.
More specifically the 11 16v/10mf caps on that board need to be replaced... Not expensive, I do them for under $100.00 dollars..

Kinda dead


techwolf, you nailed it, control board is bad, I have personally checked the tact switches and they checked good with Ohm meter but the meter lies, problem is module/board is kinda pricey and individual tact switches are not listed individually on parts list, you also have to be carefull that you get the correct one, there are 3 versions of your posted model #, AV48WP30, AV48WP30A, AV48WP30ME, be sure to check which one you have, should be able to order module here; www.partstore.com I have tried cleaning tact switches with "blue shower" but fix doesn`t last, have to change module out, good luck, BMW Rider
