Question about Toshiba 35A44 35" TV

1 Answer

Top half of picture visible on Toshiba 35A44

I have a Toshiba 35A44 set that had some damage due to a nearby lightning strike. The set powers up and volume is fine, but only the top third of the picture is visible. It is not a compressed picture, just the top third is visible. I took it in to a repair shop, and they thought it most likely needed a new vertical circuit board. They said the board is no longer available, but I'm not sure if that is true. Anyone have any ideas?????

    They said they'd need to send it out to get it fixed. They claim to have called several shops to see about rebuilding the existing circuitry, but have not found one willing to do it. I don't know if it's that hard to find a shop willing to rebuild it, or if they are just feeding me a line.

    Hi Shuttle83,

    Thank your for your honest opinion. I'm not trying to second guess the repair shop, I'm just a little dissatisfied with their service. They've had my TV for a month and a half, and everytime I ask what the status is, I get a different answer. They've also said they would have the technician call me on two different occassions, but the call never came. Today, they finally told me they can't get the part and haven't found anyone to rebuild it.

    I'm just trying to decide if it is worth taking it to another repair shop chalk it up as a loss. My plan is to go talk to another shop and see if they have the in-house expertise to rebuild the board since it appears a new board is not available.

    Ideally, I'd like ti get it fixed because it should still be cheaper than buying new. So I guess my next question for you is, assume I find someone to rebuild the existing board. Is it true that the surge could have damaged other parts that may cause problems down the road? My computer was also damaged and I was told that I'm better off buying new, because they could fix something now and a month from now, a new problem pops up. I'm wondering if the same olds true in this situation.

    Thanks again and I appreciate your opinions.

Hello cjc07 The bad news is they are correct the vertical board is bad, the good news is the board can be repaired. Now it's what you have to do to repair the board is the problem. first you need a schematic and multimeter to show you what the voltages are on the board then using those voltages you can tell which components on the board are bad. Now here is even better news, the board might not have suffered all that much damage, maybe just enough to take out one component in the power supply which could cause this problem to. The fact is this set can be repaired, here are your options. 1) replace board 2) repair board and associative circuitry (this includes possible power supply damage.) There you go. If the board is no longer available, then option two becomes the only option on the table. Is the shop willing to repair the board and associative circuitry? If so take it back to them and have it done if you wish to have it repaired. Thank you, Shuttle83

    It is a daunting task to do so, but it can be done if you have the right equipment.

    Let me be frank with you, if I may?

    Your set was hit by an induced spike caused by a nearby lighting strike, that caused some sort of disturbance (spike) on your electrical line which in turn sent that spike into your television, which damaged some components in your power supply section and in your vertical section (the board). This means you either replace or repair the board and you replace those components in the power supply section.

    That being said, I know you are leery of paying the money for the repair of the set, but second guessing these guys mainly when they have given you an honest answer is not a good thing to do, how I know it might be an honest reply is because they said they called around to other shops to see if the other shops would repair the board, TV repair people normally won't admit to a customer having to have another shop do work for them.

    You need your set repaired, they told you what is wrong and gave you way to deal with it, you asked for a second opinion, I told you that the board can be replaced or repaired, as some one once told me it all up to you now, do what you want to do, have the board repaired or replaced or just scrap the television all together? It's your choice.

    Not trying to sound argumentative, just trying to stress the point that two non-related opinions have been given.

    Thank you,

    Hello cjc07,

    I thank you for understanding my intent, I know I come off kind of harsh, that's one of the things I have to work on.

    You are right to feel the way that you do. Let me answer some of your statements and questions:

    S) My plan is to go talk to another shop and see if they have the in-house expertise to rebuild the board since it appears a new board is not available.

    R) Not too many places these days have that expertise because so many new techs are not taught component level troubleshooting and board design (you have to go to the engineering level now to get that) sad but true.

    Q) Is it true that the surge could have damaged other parts that may cause problems down the road?

    A) Yes something else could be on the verge of breaking down

    S) My computer was also damaged and I was told that I'm better off buying new, because they could fix something now and a month from now, a new problem pops up. I'm wondering if the same olds true in this situation.

    R) Yes and no, Have you ever seen a movie called Catch 22? This is one of those "save the bombadier" situations. Something happens and then you have to respond but the response is conunterproductive to the very thing you originally set out to do. That's how the whole power surge thing goes.

    S = Statement
    R = Reply
    Q = Question
    A = Answer

    I hope this helps

    Thank you,

    Actually rebuilding the board is not that hard, the hard task is finding all of the other issues that lightning strike may have caused. That is the hard part, however it can be done with the proper equipment. Try taking the set to another shop and state that you need the vertical board replaced. Question do you know which board is the vertical board? If you did my shop could rebuild the board with no problem, because, what is involved is testing the components and replacing the ones that are out of specifications. This is not a hard job it is just tedious. So, I wish you well in whatever you decide to do.

    Thank you,

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.


Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Sorry.
Contact the authorized service center. OK?

Will a nearby lightning strike cause a power board failure?


It could happen yes it would depend where the strike entered the TV. Not all lighting strikes hit on the electrical lines, on a TV they can come through the cable, as well as a antenna if you have one hooked up.

Power supply failed due to lightning srike.


Hi

The first parst affected by the lightning strike are the reservoir capacitor, a big cylindrical component in the high voltage section of the tv, which normally blows up, opening the top cap, and the NTC. Please, check these components and replace the damaged ones.

Toshiba 37AV500U damaged thru HDMI input.


The lightning stroke has been effected to the main digital board to your TV. It will be best to replace the main digital board as card basis, rather than trying to repair it. Before replacing the board, a through checkup should be done. Contact any expereienced service technician for help, as this work is a very skilled one. No body can predict about the damages to a lightning stroke, as there will be trillions of voltage present for every stroke, and even a slightest voltage can damage so many components in a TV like equipment, as it is designed to work for 110 or 220VAC.

We had a tree struck by lightning last night. Now, our truck and sports car, parked 10 feet away, are both showing problems with charging system, (truck) and ABS, tracking system, and active handling...


Yes. Although the tires are suppose to insulate, there is enough humidity to allow the air to carry a charge. The ECM for example, can be interfered with by Radio frequencies. A lightning strike produces all kinds of freqencies beyond visible light.

You should document the tree strike and park your vehicles back into their spots if you do not already have photos of the tree damage showing the vehicles in the foreground or background.

This is comprehensive coverage with hidden damage discovered within a recent timeframe of the original event.

No picture onTV screen only audio after lightning


May be your picture tube got damaged in that lightning. This may be an effect of the magnetization of the picture tube due to a huge electric current passing near it. Try demagnetizing the tube and if it doesn't work get it replaced. Try having a properly working tube of an older television as modern picture tubes lack quality.

Lightning Strike?


Assuming this line is across the screen horizontally (side to side), this means the vertical deflection circuitry is dead. In late model sets, there is a Integrated circuit package which drives the vertical yoke coils. Possible defects: the I.C. itself, bad solder connections where it solders to the board, missing voltage source to this I.C. (often around +24 volts), or a bad electrolytic capacitor in the associated circuitry. This latter often results in a non-linear picture, or less than full deflection condition, rather than a thin line only. It is possible lightning caused this problem, (I've seen some rather illogical damage from lightning ) perhaps it produced enough of a surge to pop the I.C. or a fusible resistor in that voltage source noted above.
