OK sorted the problem on my set. Replaced the capacitor ref: 2455 on main board it is a 47uf 25v but i was told a 35v will work as well? But mine is a 28pw6506/05

Hello, you (tech) can try this remedy - 1500 = fuse (250V/4A) - 3523 = resistor (47R) - 3527 = resistor (0.22R) - 3532 = resistor (2.2K) - 6500 = diode GBU4JL7002 - 6523 = diode 1N4148 - 7520 = circuit TEA1507P/N1 - 7522 = transistor BC847B - 7521 = transistor STP10NK80ZFP - 6526 = diode BZX384-C22 - 7515 = optocoupler TCET1104-G - 3526 = resistor (0.15R). - 3526 = resistor (0.22R). If you need more info please advice. Arpi

Im having a problem with my TV turning off and the standby button flashing 7 times, after it shut off. What can I do.

Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.

The TV was working, and then randomly just shut off and won't come back on. It still makes the click noise when i turn it on, but only once instead of two. The standby light keeps flashing four times....

Hello melanie Hi, in my experience as a TV technician, that would usually be a shorted part, the horizontal output transistor, that part powers the HIGH Voltage section. Very Lethal, the power supply detects this bad part which in turn makes the unit go in standby so as not to damage the TV much further. mMy advice is go seek a tv tech to repair the part.

My Samsung LN52A550 LCD TV will not stay on.

The ticking noise usually comes from the power section of the tv. Usually it is a capacitor failing. As far as the cost of repair this can go either way ie cheap or expensive. It will dpend on what exactly has failed and if it requires a board replacement or just a part.

I'm going to assume this isn't under warrenty anymore. It is covered if it is. You need to get some repair estimates from Samsung and any tv repair shops. Then keep and eye out for a replacement. Make sure you include any shipping costs or other costs when you are totaling up the estimates. If it gets close to the replacement cost then you will have to choose if you want a new tv or have a repair done.

Hi, have a philips 42pf7321d/37 tv that won't turn on, I replaced 2 capacitors that were bad but when I tried to turn it on again two leds on the power supply turn on making a clicking noise they stay on...


The clicking noise and the leds on mean that there is an incorrect voltage value detected from the main controller board. When this happen we say that the main controller is forcing the PSU to standby, sending the set in protect mode.In protect mode only

The PSU can be tested bridging the low voltage control lines that are turning the higher DC volts from PSU on.

The procedure to test the PSU is illustrated in the following article. I wrote the article for LCD, but the procedure is more or less the same on your plasma. Simply disregard the part on inverter (plasma work in a different way and have no inverter or backlight system) How to test an LCD TV or monitor PSU

Bridging the voltage lines is a repair suitable for an experienced technician. If you are a DIYer, better testing the resistors and components near to the faulty capacitors by reading Ohms to check if they have continuity. This operation is done with power not connected.

If you need to replace the whole board, here the part number: POWER SUPPLY UNIT LJ44-BLAH101C PHILIPS. The part is temporarily out of stock, and may be available ordering from Philips.

Here the service manual:

Polaroid 26inch lcd tvred standby light on but power wont turn on. I've unplugged the tv, changed the batteries in the remote. The tv stays with the red standby light only.

You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.

Tv went off with strange noise and we smelled something burning, but no flame. TV will not turn on. No light, nothing. IS TV fixable or should we replace? It is a magnavox tv that is at least twelve years...


as you said.. you have defective horizontal output transistor! and or the power section, please check the power regulator first. this is repairable..

You can check any 5v input to the microprocessor and sound is the audio IC whether have any voltage input.You can try to troubleshoot but please be careful.I don't have your model schematics but oher philip models.

Is the sound a high pitched whine? or an arching noise? since half the screen is black I would tend to believe it is a deflection problem. Which is the Horizontal section were having problems you would experience this. Ok first get a schematic for this television. Either contact the manufacture or get one from Open the set up. Determine where the sound is coming from I guess would be the switching transformer or the IHVT (Integrated High Voltage Transformer) Then if you have one get hold of your multimeter set to dc volts and begin to measure the power supply voltages leading to the Horizontal section. Your problem will be in these sections.

This sounds like one of the capacitors has dried out. They are metal cylinders containing 2 rolled up strips of foil separated by a gel. Over time the gel can dry out an eventually the strips of foil touch creating a short circuit. A TV repair shop should be able to replace the faulty component relatively easily. I wouldn't recommend trying to do this yourself unless you are very confident you know what you are doing, the voltages present in a CRT TV are very dangerous.

TV starts but Does Not show picture or no sound

The Tic Tic sound is a result of the high voltage shutdown circuit. Thats what the circuit does if theres a short in the Highvoltage sweep. like maybe a shorted horizontal output transistor??. The only way to really tell is go in and measure the start up voltage and if the Hivoltage comes up and shuts down its a fault in the shutdown or Hhv regulation circuit . if it dosent come up at all then the faults in the Horizontal sweep circuit . Hope this explains a bit? good luck
