Question about Philips 37PF7320A 37 in. HD-Ready LCD Television

1 Answer

Power supply I have the same problem but the power supply part # is cofusing and nowhere on the net is a picture of it. Service shop told me the part cost over $200 but some part dealers are telling me about part that cost as little as $65. Can you help me with the right part #? I wonder if the PS will burn up again.  One part # is 310432836301  PWR SUPL A other 310432836211 for $261.62 Thank you

    Thanks for the part number.  Just before you put it here, one supplier sent me a wrong part. Same TV and they come with a wrong power supply.
    I noticed where the little sticker on the wrong part is, so I doublechecked your and viola, it's there. Pretty hard to see. What's confusing is, that the circuit board has a similar, bigger number etched in but it's not the right one.
      One more thing. Philips was rude and no help at all. So you can guess what my next HDTV will be.  Not Philips!

    I'll tell you next week if the power supply was the problem.
    Thanx again.

    "3104 328 38621 Is the part number for the supply."
    Thanks. It came in and the problem is gone. Small resistor was blown a Philips is using a bigger one now.

    Pretty much the big number is etched on a circuit board is just a generic number for the pcb board before any components are added. If u are looking or a part number look for the 12NC. I can't say too much about philips being rude too you. But im glad i was able to help out.

    Original 470 Ohm resistor was a I watt. Replacement is a 2 watt. Glad I could help.

I have a hitachi p50h401 i was told it needed a power supply n 10 amp fuse i have replaced the power supply but not sure where the fuse is located. so i still have no power. can you help please?

Download the service manual to your Hitachi P50H401, from net. you can't find it for a free download. most of the service manual to Hitachi will be a paid download from such sites.
Service maual will have all the details about circuits and printed circuit board, and part loacations. Ok.

Sharp lc-26d40u No picture

I have a Sharp Aquos LC-40E77UN with the same issue, and have tracked down a single burned capacitor at C7816 on the power supply board, and am looking for info on the capacitor in order to replace it. (Power supply: RDENCA354WJQZ / Delta DPS 208BPA). - Any help with a schematic would be appreciated!)
Since you say the picture went out, it is possible that you might have the same problem, Bad/failed/leaking capacitors are, unfortunately, quite common in electronics. There are volumes of info available on the subject.
Replacement power boards can also be purchased. One for my TV runs about $60 to $120 depending on used or new. Since I was able to see a good picture on mine for a few seconds, despite the burnt out capacitor, I'm opting to try and find/replace the cap myself (using the proper safety procedures), or at worst, have a repair done to the power supply.
Backlights should typically last around 60,000 hours.

No picture or sound

Make sure that there is actualy power going to the AC power source where the TV is plugged in. You can re-set the TV by disconnecting the power for about 10 seconds and then connecting it back again. If the set still does not start it will require service.

If the set is dead it is most likely the main power supply board that failed. The service tech would replace the power supply and also investigate to find the cause of the failure. Sometimes another board could have a failure and cause the power supply to be damaged.

If the set will not start up, it will require shop service. You can call Panasonic tech support to find out the authorised service rep for your area. Check to see if the set is still under warranty. If not, it will be expensive to service.

Had the same problem, Insignia 32 would click on then go off. About 6 months ago I found (somewhere on the net) a guy who explained that he changed blown capacitors. As I recall he even posted a picture. I found the blown capacitors and replaced them with larger capacitors (less than $20) problem solved...
But now my screen image is showing only half a picture and is pulsing on a off.

Service shop

The power supply can be repair, but many service techs rather not to, because they are switching power supplies and it can be a bit more difficult to fix them.
Many power supply components failed because they are expose to high heat generated internally when the TV is working, if the capacitors are working with temperatures of 170-185 degrees fahrenheit, their life expectancy is about 1000 to 1500 hours.

Is the power supply completely dead ? If so with this model of power supply its very common for the resistor 3318 on power supply to go out. Causing the power supply to completely die. Take out the resistor 3318 its a 470 Ohm 1W resistor. check it if it doesn't read around 430-530 Ohm Its gonna be bad ( most likely ith will read in the mega ohms. Replace with a 470 Ohm 2 W resistor. Also check power supply for cracks

Westinghouse LVM-37w1 Goes immediately into standby mode

Power suplly. In my case I should have done research on a lot of things before purchase - westinghouse doe snot acknowled any power supplly uissue but they would say that, and this is a direct quote from them, "Westinghouse's failure rate is less than 2%, which is great by industry standards. Unfortunately, when you sell millions of televisions, 2% is still a lot of televisions. There have been no recalls on this model (or any of our models), but it's not surprising to find a similiar issue on more than one of millions of televisions."

In other words they calim there is nothing that is really their fault. However the first thing the repair guy said before he even looked at it was "Power supply". He opened it up and tested - power suplly. However to complicate matters more I made is huge mistake of buying into a scam offered by eCost via . A two year, 100%, in home service, warranty. Bottom line is since June 8 my Monitors has not worked and sine July 7 it has been sitting untouched, not here, but at a rprair facily over 50 miles away. As of yesterday August 7, I was told Westinghouse no longer makes or provides power supplies for this unit. On top of that the repair facility will not return it to me unless i pick it up why? Because it can't be fixed and because will not pay them to return it to me.

So solution at thi point for anyone with power supply issues is to try and repiar it yourself. And then in the future never purchase anything from westinghouse again. (And if offered any sort of 100% all cost covere din home warrabnty from run away screaming)

Power Supply

As far as i know the power supply and the control panel come as one unit if you can send me the complete model number and the serial number i can check to see if they sell the power supply seperately and what the cost will be.
