Ah! if relay does not click when set turned on either main board (controls everything) or a missing voltage in the Standby part of the power supply.

you tested the filter caps with what?

i think your bulb is shot must be replaced

SOURCE: My 50 inch philips plasma tv wont come on. all it

There are a few common gotchas for all plasma TVs:

Most commonly, a sustain board overheats and burns out; sometimes that prevents the TV from powering and sometimes it does not.
Unfortunately I don't know enough about your particular model to tell in which category it falls.

Second, the power board either breaks too (sometimes as a result of a sustain defection) or filter capacitors on it dry out and prevent the board from powering on properly. This, in turn, is detected by the protection circuits on the power board itself and treated as a short circuit, thus shutting down the board to prevent further damage.

In my experience 80% of the time the problem you describe is caused by burned ZSUS board and 20% are due to defect power board.

As I said earlier when a sustain burns out it sometimes takes down the power as well. Which is to say do not presume that just one board has gone bad.

One of these days I am planning to post a DIY troubleshooting guide for plasma TVs at my site http://www.coppelltvrepair.com .

It's easier than many people think.

For example in your case I'd try to power off the ZSUS board - the one on the right side of the TV when you watch from the back - and turn it on again. If it powers on then the problem is in the ZSUS board.

In fact, there are quite a few such guides circulating around the net.

The problem ,of course, is that it takes time to understand and apply them properly.

Unless you have a lot of time to kill or a desire to enter the field of TV repairs it's usually better to just pay off a good technician.

Developing the qualities to find a good specialist is a challenge well worth the time and will pay many times in life.

The same can not be said very safely for the qualities of repairing plasma TVs :-)

The capacitors for 2533,2540,2541,and 2508 should be replaced. They are all 100uf 16v surface capacitors. Those capacitors are sold on amazon.com http://www.amazon.com/Rubycon-Electrolytic-Capacitor-IMPEDANCE-Continuous/dp/B0015A8U9M/ref=sr_1_2?ie=UTF8&m=A6Q8GCHJGURD6&s=industrial&qid=1225140147&sr=1-2

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

Panasonic th-50pz800u shuts down and i can not turn back on, red light flashing 2 times, sometimes 10 times


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Tv will not come on. Red light blinking on bottom left front. Red light blinks 7 times


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. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

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 HELPS..normanw1@yahoo.comj

Red power indicator is lit, this will turn to a blue light with the Insignia logo lit when it comes on unfortunately it will not turn on either manually or with the remote.


Hi:
Have the power supply checked for puffy capacitors that are swollen on their tops. This is a common problem with LCD televisions. The problem is the five volt standy voltage is to low to turn the set on or operate the Micro. These caps are usually valued at 1500u,voltage rating of 10-16volts. some units use 3300uf rated at 10 volts for theirs capacitors. I suggest you use 2200uf rated at 16 volts.

Element elchs321----tv cuts off on its own. when tv is plugged up, the light at the bottom is red and you can hear a crackle, the light turns blue but no picture or sound. Help


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors. That crackling sound is the capacitors burning out.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Red power light is on but tv will not turn on...no blue light with either the remote or power switch on the tv.


Dear quiltcat1,

With the conditions as you say, there are components in the monitor, exactly on the power supply board is not working properly or damaged and it usually Capacitor.

The solution are:
1. Open the monitor case
2. Look for Power supply board, you will see there are some capacitors.
3. Look for bad capacitors which bulged at the top.
4. Just take out (you need a soldering tool in this step)
5. Replace with the same value of microFarad and higher values for Voltage.
for example: 1000mf 10V replace with 1000mf 10 to 25 V will be fine.

good luck.

regards,
dm
