There is no such breaker. Fault with main board. Damaged component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too will be necessary.

I would speculate that you may have faulty capacitors in the power supply section.

These blink code is fault indication. With Philips brand TVs, we cannot read these blinks as they appear. Means by digits. There is a special procedure to read these blinks. If you wish to get more details about the blinking codes reading procedure to Philips TVs, visit this site. Pull up older posts there. Details are given about how to read these blinks and convert them to numerical digits.Check the site with patience. It has so many posts, and all are related to electronic equipment repair. Check it in 'Timeslide' option. It will be easy to find brands.

most likely the power supply, buy it from http://www.shopjimmy.com/ they have the best prices anywhere. and techs to help if needed

'Z' Sustain board should be suspected. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there.

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them.MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!THAT WAS ALL IT TOOK.JUST A SUGGESTION..1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)TELL ME IF THAT [email protected]

Hello,

Your power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping that this will help in solving the problem and do take care in solving the problem, because it contain high voltage....

good day!

that is better if pull out the power supply board to your TV to check the power supply easily..

some bad capacitors is not bulged or leak look like good but the value (uf)microfarad is change so its better if your tester have capacitance meter if not try to check the output voltage of power supply while connect it to the TV and power ON..

normally it should have 5vdc,12vdc and 24vdc if you encountered voltage drop on the said voltages you have bad capacitors for example the 5vdc got a voltage drop of 4.5vdc..you have to do is replaced the capacitors that pass through..

thank you for using fixya..hope it helps.

Hi,

Good luck in solving the problem.....

This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.


Once you repair the power supply then you may need to replace other components if needed (EX: backlight inverter)!


Please rate if this helps! :D

The main Tuner signal board is the causes and the problems.That the board where it take in the incomming broadcasting signal wire plug into it.Try website like Ebay.com to buy a refurbish Tuner signal board for the replacement.

you more than likely need to repair your power supply - this is a well known issue for philips sets - pull the back panel off of the tv and check the power supply for busted/leaking or swollen capacitors replace them with the same uf/vdc you can even go a little higher on th evoltages if you would like just keep the uf the same - i would recommend ordering them off the net get the 105 degree ones not the 85 degree ones from radio shcak your tv will last longer if you do.

thanks,
michael

i would think its because they have put in 16v 3300 105degreeC and not 10v 3300uf 105degreeC if the 10v ones had blown then they should of put 10v back in it might be that the 16v are to high for the unit.
hope this helps

Hi gennadyal,

Blinking of your LED light indicated of out-of-regulation in the power supply section. There is no quick fix for this fault,the very common caused of this fault is the dried-up/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit and blinking error appear. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Hi.

I am sorry, but I will anticipate that I won't give you any good news here.

A thin black, red or green line in plasma TVs means that a column in the plasma panel is getting incorrect voltage. When the problem is stationary, and when the line appears regardlessly of the source used (receiver, dvd etc.), then you have a bad plasma panel. Ususally the ICs integrated in plasma panel connectors start failing, or there is structural damage to panel.
Because of the cost of the panel, the TV is usually considered beyond repair. The problem will generally get worsening in time until you cannot use the TV anymore

Regards.

Ginko.

Sounds like a problem with the power supply or display board/main board. Time
for a service call.

How many times does it blink? That's a service code
diagnostic to what the problem might be
