Question about Philips 51PP9303H Rear Projection Television

9 Answers

No audio or video just chirping

I have changed the two stk392-120 ic's. The kit includes 12 resistors that i didn't change. These tv's do not use 1 watt resistors so don't tell me to change them too. After changing the ic's i still have the same problem. This is the dptv345 chassis. Does anyone on here actually know what causes this?

    I can't change resistors that don't exist!

  • andthehorseu Apr 15, 2009

    It's sounds like it's coming from the power supply board.

  • andthehorseu Apr 15, 2009

    The chirping sounds like it's coming from the ps board.

  • andthehorseu Apr 17, 2009

    Didn't help. I'm going to try changing the regulator.

  • andthehorseu Apr 21, 2009

    Didn't work.

  • andthehorseu Apr 21, 2009

    None of your information has worked. With so many having the same problem, i have to believe someone knows what's wrong with it.

  • andthehorseu Apr 21, 2009

    It's a Philips 51pp9303h.

  • andthehorseu Apr 21, 2009

    Please don't waste my time answering if you don't know what you're talking about!

  • andthehorseu Apr 21, 2009

    You gotta be kidding me?????????

  • andthehorseu Apr 21, 2009

    I have changed the 3 power FET on the power supply board and everything else checked ok on it.

  • andthehorseu Apr 25, 2009

    All the voltages checked ok on the power supply board.

  • andthehorseu Apr 25, 2009

    All the voltages checked ok on the power supply. I have already changed the 2 FET's for the horizontal output on the ps board itself. There is another FET that is the h/o driver on the main board and an ic that i believe is a gate. I'm going to change them and hope that was the problem.

You are telling us you changed resisters for something other then the power supply and chirping is comming from the power supply well have you checked the load on this PSU "power supply unit" to make sure your reapair is in check? Have you hooked this up to a testing unit to test the value of the current after your fix? Well I do not trust you have thus you put us down saying "this site is no help" Try checking the negitive at the door and ask me some questions maybe I can help!

No audio or video just chirping - icon_quote.gif
Hi!
First what comes to mind is that power supply had gone bad. And so it
can be 2 cases:
1)The problem is located in a "hot" part of power supply. The sound you
described says that the TV begins to start and then shuts down.In this case is
necessary to check the feedback circuit elements like photocouple, transistors
and diodes.Except it replace the electrolythic capicators in "hot" part.

2)The problem is located in one of secondary power circuits.Possible short-circuit or
bad electrolythic capicators.Check the circuits with multimeter.

Its a faulty power supply board issue as per the details you have mentioned.if any components are faulty that can be replaced and the power supply board can be repaIRED,but if the track of circuit are getting short it cannnot be repaired.as you mentioned the readings of all the components are showing ok.very correct.if the circuit track are short it will show all the readings of the components perfect.but the only solution is to replace the board.that you can get from

If one of the secondary supplies is shorted, the power supply will "chirp" when plugged in. This is the power supply's way of protecting itself and this usually happens when the horizontal output transistor is shorted. The only real problem I find with front AV jacks is that they crack loose from the board, because they are subjected to the extra stress of the AV jacks being constantly plugged in and unplugged.

Hi andthehorseu,
A full, hard reset requires the power cord to be unplugged for at least 4 hours.  However, that probably will not solve the problem.

The set has gone into protection because of a shorted condition somewhere within the several sections of the tv.

The chirping sound can come from several places.  There are over 3,000 components in this model and there are about 100 parts that can "chirp" under the right failure conditions.

You should try to decipher where the sound is coming from.  Listen very carefully and up close to see if it is coming from the speakers or from within the set.  And from the front or more towards the back of the set.  That will help considerably when you call the tv service people to arrange for their visit.

As you may know, service on big screen sets in the home always run over $200.  It is one of the expected obligations that go with owning one of these big, complicated monsters; the price of sensational enjoyment - one way of thinking about it!

Taran.

    Hi andthehorseu,


     It  is either a shorted Horizontal Output Transistor (HOT) / Power FET (whichever one is used in this case) or the IHVT (Flyback Transformer) has developed a short in its windings. In ether case both components will have to be replaced. I would suggest you have a qualified TV technician come over and troubleshoot the problem and give you an estimate on the repair.However, if you are doing this repair yourself take into mind that the HOT and the IHVT (flyback) are in a series circuit configuration and if the Flyback is bad I would change out the HOT also, and vice verse.

    I hope this helps,

    Thank you,

    Taran.

Hi,

The STK's were replaced because a problem in the convergence. This problem (convergence) in most cases allows you to turn on the set just the screen looks out of geometry (by the way the resistors are critical parts that fail together with the IC's. To get the tv back on is needed a check up in the power supply and other areas related to high voltage power supply.

Thanks

Hear chirping sound from power switch, keeps tying to turn on, but no picture.


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • No Audio/Video - TV Makes Chirping Sound
701cb04.jpg
77ea520.jpg
f0900cb.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

There should be different HDMI slots on the back of that TV. Switch you HDMI cable to use another slot. Change to that HDMI slot on your TV menu. Sometimes the ports go bad, or there is something messing with the signal.

The HDMI can carry sound and video. Make sure that in your tv menu that your tv is setup under audio has the receive audio from hdmi as well.

Yes - But Ddent will not provide any instructions or support with your repair. If you need that goto sites such as www.TVRepairKits.com instead.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.
