Sony PFM-42B1E fault diagnosis

Hi there,

I know this query has cropped up before, but I would like a little clarification on the subject if anyone woulkd be kind enough to help :-)

I have a Sony PFM-42B1E and would like some insight into the diagnosis of the fault it is suffering with. This is what happens.....

"Pressing the ON button causes the unit to attempt to start up 4 times ( the fans come on, the screen flickers but nothing happens) and then it stops trying to start and the red standby LED flashes 6 times, after which this 6-flash sequence is repeated. Pressing the ON button turns the unit off and the standby LED stops flashing"

Does this "6 flash" sequence indicate that a particular board has failed ? If so which one would it be? The screen is good, as on the odd occassion it will fire up, but then goes off again.....onto the 6-flash red LED standby light.

Any help on this matter would be highly appreciated as would a source for a copy of the service manual for this model.

Thanking you all in anticipation,
Regards,
Roger

    Have exactly the same problem today. Would be very interested to find out what the problem is if you diagnose it. Four start ups with flashing red led. Then flashes red led in groups of six.

    Found this on another site...



    Reverts to st/by at sw on with 6 flashes from LED:



    over-current protection circuit (Q600, 602) is operating, usuallyprobs in LOP. To identify the cause, first dis FOP chip (IC501). If set switches on with frame collapse, replace IC501. If set fails to switch on, dis HT feed to LOPTx. This should give 4 flashes of st/by LED (no horizontal fly-back) showing that problem is in LOP. Check LOP comps before condemning LOPTx. If st/by LED continues to flash 6 times even with LOPTx disd, check R620 (270K) & R622 (470K) in over-current protection cct.



    I'll try working out what this means!

Six flashes from standby light after 3 attempts to start up with a flash from the screen 100% means the PDP panel is duff - I AM A SONY ENGINEER AND THIS IS CORRECT.

I am the guest with the same problem that posted messages above. The TV needs a new Fujitsu plasma panel - see here http://www.eserviceinfo.com/download.php?fileid=33421 for the service manual. Looks like it'll be sold for parts on ebay!

LOPT refers to CRT based TV, not plasma (unless the author is confusing it with the SUS or Drive circuit)

Scan lines missing


wow..that's most definitely a video drive error. 1. Check to see your settings are good still. It's not out of the realm of possibility that something glitched in the settings. 2. Missing information is a video drive issue, period. I'd suggest that you have a video board that's truly unhappy. Is this still under warranty? Hope so, since these service calls can run some serious dough.

Sony Tv PFM-42 V1 doesn't show any picture or tv menu


This is a common problem with plasma tvs You did not mention whether you could generate any sound like through your dvd player or something like that. Whether you have audio or not makes a difference on which board may be causing you the problem. Just because it does not have a picture for tv viewing does not mean it won't produce some type of sound through your av1 input. Try it and I'll try to be more specific.

I have a sony pfm-42b1 plasma tv with 2 vga inputs an 1svideo input.. i want to connect my ps3 hdmi cable to the vga input. i purchased the cable but nothing shows.. thanks for your help


you should change it from hdmi to cable. You can do it only on a hdmi tv when you do that you can use it for the pfm-42b1e because i had the same problem too. when you plug your ps3 to a hdmi tv you go to settings-display settings- video output settings than you change it to av multi. After you do that you can use it on pfm-42b1e
