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

2 Answers

Service shop They told me it's a power supply. I just noticed, that we communicate on two postings. The part # you gave me is right. I even have a picture that I can e-mail to you. I hate to change it and find it was a mistake.  Can the power supply be repaired?  I'm not trying to be cheap, but I'm tired to be fixing new things. It seems to be happening more often nowadays.

    You are right, it was resistor 3318. Completely out.
    The new PS had a bigger one, so apparently Philips realized their mistake and corrected it. Not fair to the customers, who have to pay around $400 for such a repair.
    Thanks to you, it cost me less than $100 from Vance Baldwin electronics.
    Thanks again!

    Same problem here. Will not turn on and has 6 red blinking lights.

  • Jerry Krauz Jun 08, 2008

    For me it was the resistor. As advised, I measured and that one was dead. Had I known that before ordering new power supply, I could fix it for a few cents. The board was not very expensive, with returned core, so I don't mind. If you can solder, follow the advice by jdbouncer, above.
    Philips realized their mistake and the new board has that new bigger resistor. It should last now.

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

Hello, I"m having the same problem. My TV will not turn on. The green light will turn on for a few seconds...then the light turns red and it blinks 6 times. Is this post related to model number 37pf9631d/37 ? ... Could it be the resistor issue ?

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

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. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Now i've noticed a crackling + no picture, but still great sound


This is something of an off brand model and about the only advice I have is if someone takes it apart---begin by a physical exam of plugs etc and then do some voltage checks in the power supply.

You might want to also GOOGLE the brand/model number to see if any parts are even available for it.

My guess is parts are slim or do not exist.

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.

TV's on. No Picture...No Sound


Have a problem with Zenith 37 HDTV. Medel number: Z37LZ5D As wathcing TV, along with 'pop' sound, TV went dead. LG service center gave an advice to unplug the power cord and press ON/OFF power switch about 1 min. Then plug power back and turn on the TV. Well, the green light blink for a while and solid green, but still no screen, no audio. Search the Web and someone suggested to replace Power Supply Board which will fix the problem. Again, search the Web and came out with Power Supply Board. LG Electronics/Zenith 'Power Supply Assembl' with $124.95 from PartStore.com. Is it the right solution? Do I have to replace entire Assembly Board? not just replacing some fuse? Any cheaper way to do? If I have to replce PSA board, any suggestion to how? Comment posted on Apr 22, 2009 I have a basic knowledge of electric and electronics, such as rewiring entire house for renovation and assemble entire computer from scratch.
Actually, the TV belongs to my father and the problem that I stated was based on what he told me.
So the question is based on the symptom that I posted, how sure are you that the problem is the Power Supply Board?
Is it good to order PSB? Comment posted on Apr 23, 2009 Purchased 2 and half years ago. Expired one year warranty. Comment posted on Apr 23, 2009 Zohail,
This is LCD TV.
There is no problem with the wall socket nor current.
I put other appliances on same wall socket and worked.
It has to be internal problem.
As I mentioned on the main post, there was a 'pop' sound while watching and TV went dead.
Turn on remote control, there is blink green light and then green stays on, but no sound, no screen.
Turn off remote control, light turns red. Comment posted on May 14, 2009 I fixed the TV.
Orderd power supply board which cost me $136.51 total.
Replacing was simple.
Just removed the rear panel cover then electronic board housing cover.
Took power supply board with all the connector cables and replaced with new one.
Problem was a transformer connector which got burned and blow up the plastic cover.
But no problem with fuse and capacitors.

Thanks all for advises.
