Magnavox /Philips 37mf321d/37 scaler bd problem.

I have a Magnavox 37mf321d/37 LCD TV with a bad scaler board. (The analog channels fade to black and white after a few minutes.) The board in my set is part # 313815866271. PartsStore.com lists part# 313815864951 as an alternative scaler board for this set. This would save me about $200. Does anyone have any experience using this alternative board in the model 37mf321d/37? Any problems or fitment issues?

Sounds like you need to repair the power supply, don't fret, it can be really easy.  Here is a pair of youtube videos I made after following some advice on this website from other posters:

The only way that I know of to eliminate this problem is to buy a new TV. My ILO TV has been repaired twice since May 08 and it went out again for the third time. The problem starts out as an intermittent problem.... You turn the TV on, the audio is fine but there's no picture, you will be unable to change the channel or volume whether you're using the remote control or the buttons on the TV.
This TV should have been recalled. Don't reward the manufacturer and retailer for their bad behavior, buy your next TV from a different retailer.

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

SOURCE: my philips lcd tv has sound but no picture what is

change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

37mf321d won't turn on- no busted capacitors


Hey Superdave,
Does the whole tv turns off when the picture turns off ??? What you're describing sound like a defective CCFL backlight. This would make since why someone threw it out because the repair estimates of replacing the bulbs would knock your socks off. Most will suggest ordering a new LCD panel assembly which would cost way more than what the set is worth. On some sets, when a CCFL is out, the screen will come on for a few seconds then go out. On other sets, after so many "lamp failures" logged in memory, the set will not power up at all and just flash trouble codes through the power indicator.

Philips Magnavox 37" LCD Flat Screen 37MF331D Have replaced power board,main board,hit power a faint light on whole screen for about 2 seconds the nothing.


Disconnect the LVDS Cable that runs from the small signal board to the display panel and apply power,if the screen comes on,the Small signal board (aka Scaler Bd ) is the faulty board. other than that,all that's really left that has gone bad for me is the logic board.

Get Dtv with my 37MF321D


This TV does not have built ATSC/RF Tuner.
I have this same model TV, the analog reception is snowy even with outside aerial. I have to get the Govt, Set box converter and the picture is now perfect! Apply for the Govt Digital TV converter Box and you will enjoy it
