SOURCE: Cracked LCD Screen on Sharp Aquos LC37D43U 37-Inch 720p LCD HDTV

Most LCD's just went down in price by around 2-400 dollars. I would suggest buying a new one. The cracked screen might mean that the liquid will ooze out and get worse and worse as it ages. However, it may only have a crack and not get any worse than it is now. If you can live with it and it doesn't get worse, you can view it that way for another 10 years and be fine.

The fact that the LCDs are cheaper now and you only have a 37 inch, you might consider getting a larger one that you have had your eye on for a long time. (Note: even though I am a firm believer in LCD's over Plasma, plasmas are a few hundered dollars cheaper and if you know your children are prone to breaking things... it might be the way to go.)

Replacing the screen is possible, but more costly than the new T.V.

SOURCE: Sharp aquos hdtv has sound but shows a white screen

yes and no. That particular tv you have is done for, but if you just purchased it 6 months ago, you are still within you 1 year warranty with sharp. they will ask you to take it to a authorized service center and you need to follow through with the process. about a week or 2 will pass and the service center will deem the unit unrepairable and sharp will replace it if they cant solve the problem. give em call..good luck 2u

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

I can suggest you to bring this to any TV repair center near you because I believe they repair any brands like in my place sicen this unit of yours is just a generic type of a television set and ShopNBC only has a limited 1 year warranty for this and this one really has alot of problem and complaints from other user...

Good luck.....

I have sound, but no picture. No previous signs of malfunction. What could be wrong?


Did you check trouble shooting section in manual? Is your TV hooked up to a home theater system? Then check power source to TV. If ok , then I would suspect the lamp blew out.

Hard to fix for people without watchmaking knowledge. I'd do that in 15 minutes. Anyway - Invicta is NOT even the average quality watch company, so, can NOT charge you more than price of watch. Contact me: artkalnins@yahoo.co.uk This will be long explanation, but , hopefully you will get it right.

Protron 32"


Hello, I have a Protron 32 in. TV also. After about a month I saw a few lines verticle on the screen. I called Protron and they were very nice and said thet would send me instructions and a pick up notice for FedX. I received it in about a week. I packaged the tv up and sent it to them. I started calling after about a month and they stated they were waiting for the part to come in to fix it. This went on for about 4 months with me call in every week. Eack time thay would tell me it was going to be ship to me with in 2 weeks. After 4 months I called and was very vocal and stated that if I did not have my tv in 7 days and this was on Wednesday I was going to get on my PC and anybody that did any kind of search on tv's, Protron, Spectrum would know about my problems and how sorry the company was and hung up. The folling Monday I recieved a new tv and it was the newer mdl.I also told them I did not want a repaired tv that i had paid for a new one and would not settle for a repaired one. I have not had and trouble with this tv and it is about a year old. I hope you may be able to do the same thing.
