    Just as I thought, but as always the insurance co are trying to weasel out by saying the power board may have been blown before the fall and hence they say i am lying and trying to claim fraudulantly. is there any way at all to get an accurate date and time of the board failure or maybe off a chip or something inside to show it failed after the fall

  • lessjo Aug 11, 2008

    sorry new to this forum so i will ask again as i feel that i didnt give enough info first time round. we were putting the tv on a wall bracket 1.5m high and my mrs dropped her side i kept hold of my side but it ripped my shoulder as it hit the floor smashing the casing (but not on the power button side) then fell foreward hitting the coffee table and cracking the screen it fell hard enough to rip through the carpet and underlay hitting concrete below the underlay. following the assessors visit i was told it would be 2-3 weeks before they could get an engineer out so i turned the tv on and got a green light followed by flashing red light but no picture or sound.

  • lessjo Aug 12, 2008

    Sorry I need a real tv engineers opinion... to clarify the unit was over 2 yrs old it was fully functional before it fell, the insurance engineer took it away, and said there was a power board failure but not due to the impact,
    I did plug it in following fall to get nothing but blinking light,insurance are saying that it may not have been working before the impact, and I wonder if there is any way to tell time of failure ie date/time stored in chip or something to show it was working to date it fell.cheers

  • lessjo Aug 12, 2008

    thanks to all who have helped especially dan and robotek I will phone them tomorrow to sort it out they are trying it on because i have no knowledge of electronics

The most common thing to breakdown on a LCD or Plasma screen is the power and it can be caused by a single capacitor that has leaked or blown, causing it to not power up. Also the transformer could also failed, but there wouldn't be time on it.
For your question on the time, well they don't have anything that can tell you when a device fails as no-one has thought of that when designing electronic components, chips are like switches selecting what to function next.

The fall might have not caused the TV from not functioning but if their was a fault inside the TV then it could have being a contributing factor to it failing. By the sound of things the insurance company can fix the power fault within your claim.

Gidday Mate!

Your case is a tragedy by the sound of it. The set being dropped on its end like that will have put huge deceleration force on the screen. This will be at the base of the problems. You may have done additional damage to the power supply from turning it on, or the fault that is present from the damaged screen is preventing the power supply protection circuitry from powering up the set to prevent further damage or fire risk... just as it is supposed to to.

The fact the insurance co is saying the power supply was not damaged from the fall is open to conjecture. If they are aware that you turned the set on after the drop, they may also hold that against you. The only way they can proceed by the sound of it is to replace the power supply, or at least get the rest of the set going to check for further damage.

Now since some Insurance underwriter at a desk somewhere cannot see how the problems you have relate, they are assuming you are trying to make a fraudulent claim as you have indicated. The power supply board may have been damaged in the fall anyway. Sounds to me like they are attempting to give you the run around.

If this sounds like what is happening, accept my solution and we can continue on and talk through the options available to you.

regards
robotek

Because of that impact probably some of the parts on the main board got loose that's why you're having this kind of display on your screen , but since the uniot is new the store or manufacturer should just replace it with a new working unit...

FIrst of all, this being a plasma, once the screen is cracked it can not be repaired. The panel must be replaced. The cost of this replacement often exceeds the replacement cost of the entire TV. This is not a problem that will be covered under warranty. The set fell and the damage that occurred is NOT a manufacturing problem. Don't waste any more time on this set. It is time to replace it. I'm sorry to bring the bad news, but you are wasting time trying to get this repaired.

    The insurance company is blowing smoke. With the panel cracked, the unit will behave like the power supply isnot functioning. There are protection circuits inside that will shutdown the set when this happens. This is not a fight you are going to win without a written estimate from a service center. I have written many of these reports for insurance companies. You will need a statement from the servicer indicating that the set is unrepairable and that the cause is the broken panel. The power module could easily have been damaged by the fall. Anything we say here will have no validity from the insurance company's perspective. You need a document from a servicer.



    Hope this helps,

    Dan

  • ABRsvcs Aug 12, 2008

    Let me restate this in a clear and consise manner. I am a servicer and if you were to bring the set to me I would writ the document I referred to before. Robotek is also a servicer and I'm sure that he would write one as well.



    The set is JUNK at this point. The panel is broken, there is nothing that can be done other than to replace the panel that can resolve this problem. Until the panel has been replaced, the set will be have like the power supply is bad. This is because with abroken panel, problems will be detected that will shutdown the power supply module. This will seem like the power is not on. Unless the insurance company is willing to pay for a new panel to prove this, they should be paying for a replacement. This in nonsense. The insurance company is trying to avoid paying the claim and will use this type of tactic to make that happen. Do not let them intimidate you. You have a legitimate claim and should be able to collect. Go to an authorized Philips service center for an estimate. That estimate will include the panel and not much more as the probability of further damage is not relevant. The panel cost will exceed the replacement cost of the set and thus, the claim should be processed. If you still run into problems, have a lawyer place a call to the company. That will stimulate them to proceed.

    By the way, I normally don't do this in a public forum, but:



    Please ignore the advise posted by igi_57 and gopi20 as it is wrong. FOr the second reference, this is a plasma set not a CRT based set.

Here is your question ( is there any way at all to get an accurate date and time of the board failure or maybe off a chip or something inside to show it failed after the fall) and I will answer as all digital TVs i.e LCD, Plasma etc are able to store problem / fault history but with out Time n Date Stamp and Runing Hours.

Its the power supply and you have to get it repaired if it is not possible to repair you have to replace it ,ther is no such chip or any thing else which can tell when it has become faulty,you can just remember that if before the fall if it was working properly then it has became faulty because of the fall.it could also because of the loose connection of some wires or some wires streched out of its socket check that also. and last thing if its board ,if you get it replaced it from the company you will get the warranty of nearly six months, but if you your self get the board and get it repaired by some local engineer you will definately save some money but you will not get any garrantee or warranty and that would be more risky.

I believe that your TV's power board is not bad, however, the connection to it is not complete. It was damaged by the impact of the dropping of the TV.

In fact the board could have itself been damaged by the impact as well.

Was this a new unit?

Can you get a second opinion from a TV repairman?

Regards, and sorry for your loss!

The problem of your Plasma now is the side effect of the fall before.Maybe there is a crack of the solder joint circuit board. Crack solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

Good luck:

    If you know there is a side effect of falling down before and you want trying to repair will be more costly then it is worth. A week down the road something else could break. Your best bet would be to just sell the tv on craigslist or ebay to someone for parts and purchase a brand new Plasma TV. You might want to get a Sony or comparable brand. As they have better customer service and more parts or available for a longer time.



    hope this may help;

When you drop your tv the possiblities of not working may be

  1. Cracked circuit boards. These can be repaired since TVs usually have fairly wide open single or two sided boards.
  2. Broken circuit components. These will need to be replaced.
  3. Broken solder connections particularly to large heavy components on single sided boards. Reflow the solder. If the trace is cracked or lifted.
  4. Broken mounting brackets. These are usually made of cheap plastic and often don't survive very well. Be creative. Obtaining an exact replacement is probably not worth the trouble and expense.
  5. Components knocked out of line on the CRT envelope or neck - deflection yoke, purity magnets, convergence magnets and coils, geometry correction magnets. These will need to be reattached and/or realigned. Some CRTs use little magnets glued to the funnel portion of the CRT envelope. If any of these have come loose, it could be quite a treat to figure out where they went and in what orientation.
  6. Internal damage to the CRT - popped or distorted shadow mask, misaligned electron guns. Unfortunately, you will probably have no way of identifying these since you cannot see inside the CRT. They will not be apparent until all other faults have been remedied and the TV set is completely realigned. At that point, extremely severe purity or convergence problems that do not respond to the normal adjustment procedure would be one indication of internal damage. Give the TV a nice funeral. :( For a large screen TV, the effects may be even more dramatic.

If the TV had issues powering up earlier before it fell down, they are correct in saying that the power supply is defective. In regards to the broken screen, they can not be fixed because is not economical or the screen is no longer being manufactured.

    How old is the Plasma?

    If less then a year old, It would be still cover under the manufacturers warranty and they should fix the power supply issue and the insurance company pay for the broken screen.

  • Jaime Hernandez Aug 11, 2008

    Did the plasma worked properly before it fell down?

    Regardless how the plasma fell down, the circuit boards inside can get damage easily. There is not way for anyone to know when the board failed but certainly the fall could play a big role for the power board to failed.

The power board can go anytime but,also if it is dropped. if it was dropped hard enough and it sounds like it has been if you had to replace the screen than yes it is possible. the fall could have shorted the board out or broke a connection not allowing it to come on. if the t.v. worked before it was dropped than i would say yes that the fall caused the board to fail.

Need 4 screws for phillips 42pf9946-12 plasma tv to fit wall bracket


Best way to be sure is call Philips customer service with the model number to get the thread type and length of these--no two sets are the same here---usually most will be available at local hardware stores if Phillips does not sell them(that would be a bit more pricey and take time).

Phillps tv problem


42" Plasma Flat screen TV - recently problem started with a solid black background over top half of screen during viewing (comes & goes). A few days ago, when TV was turned on, green light came on then changed to flashing red light in 4 signal flashing pattern, but no audio or video. Phoned Philps Cust Serv and was told to download system upgrade on USB but it did not work. Philips referred us to Service Repairs who charged $85 for coming to home and without even opening the TV, said it will cost approx $1000 for "boards" plus his service, and he could not guarantee the TV would work.

Bose lifestyle 25 system and Panasonic Plasma Tv not working together


I posted the message as Tet Tet before. I can now tell you that I have resolved the problem. The issue is with the Panasonic 50Inch TV. Some people reported the same problem but only when the TV was up on the wall. It turns out that the problem lies with the metal discs which screw on at the back of the TV to enable you to hand the TV on the wall bracket. In my case I had excessive interference caused at the back of the TV (could be the fan). When I put the TV on the wall bracket the metal discs would be in contact with the wall bracket which in turn was acting as an antenna causing the iterference to the bose remote which operates at a frequency of 27.45MHz. You can solve the issue by adding some insulating tape around all the metal discs avoiding them to make contact with the wall bracket. If that fails Panasonic will swap your TV for another one like they did with me. I can now enjoy my Bose System with the 50 inch Panasonic TV. It took me three months but managed to get a solution. I hope this helps. For further info you can mail me at rizzocarlo@hotmail.com. These discs should be made of metal because they are perforating the metal screen at the back of the TV. Panasonic please change this design.
