I see this complaint all the time from flat panel/flat screen tv owners.

This is most likely caused by capacitor failure, as it needs the capacitor charge to energize the entire system.

Alot of people think that flat panel tv's are just like the old tube type, but they are wayyyy different.

First, the old tube style tv's held the charge in the tube itself, where as the new tv's use capacitors to hold the charge.

Look at capacitors like booster rockets.

The power supply might get the thing to lift off the ground, but without the capacitors as a booster, the tv doesn't fire all the way up.

I recommend taking your tv to either Fry's, or to BestBuy, have them give you an ESTIMATE.

I say that because the cost of repairing the capacitors can sometimes be as expensive as the cost of a new tv.

The reason the capacitors fail isn't due to hard use, or anything like that.
They are failing because some companies in China made like a gazillion of the capacitors, and they're cheaply made.
No quality control, made sloely for the profit.
Some fail due to cheap casings splitting open, some, the retainer seal on the tops are improperly assembled at the factory, some don't have the right capacitor gel inside of them....the companies used the wrong fromula.
And some are so poorly made that they actually explode like a battery does when it goes bad.

I hope this helps you understand whats wrong, and good luck to you.

My proview 3200 has picture but no sound

Hi gravdar4,
Power on the unit in the dark room then aim the flashlight directly to the screen, you will barely see the images. This is because your backlight is not functioning. The following reasons are the caused.
1. Power supply- missing B+(supply voltage) coming from this board feeding the inverter board. This was caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board- even the B+ was present from the power supply, if the fuse, driver transistor, driver transformer was faulty, no output to the backlight resulting to black picture.
3. Busted backlight
Diagnosing the fault istechnicaland if you don't have necessarytools and test instrumentand can't fix it yourself, I would advice you to look for anexperienced technicianto isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

When i turn on my Proview PA-32JK1A (Model 3200), nothing comes on the screen, and in a few seconds, the blue light indicating that it is on, turns back to orange .... what is wrong with it?

if you take the back off of it (only 3 big black screws)
and look at the yellow motherboard (power inverter)
on the top - left most connector

there is at the top of it one red wire in the convector
the pin it touches will be singed because of a bad confection arching electricity. clean the pin with 600-800 grit sandpaper

put it back together and you will have one working tv

Why does my TV not respond to any remote, not even the original remote control. I'm unable to turn on or off or change channels. (Proview 3200)

It can be IR receiver is not working or the CPU is getting the signal from IR board but not processing the signal properly, you can try new IR receiver board.

Comes on ,but no pic or sound.light blue screen. i think the blub is gone

You can tell if the bulb is out by powering up the TV and holding a flashlight to the tv. Put the flashlight close to the screen and see if you can see any picture. If you can see picture, then it's the backlight. If you can't see pictures it is probably a more serious issue and would likely need to be repaired by the manufacturer.

Pat I do not know if you have a warranty you were required to retain the receipt from the store for the length of the warranty period to prove you have one ,also it is a good idea to register with the company on their website so they have a record of your tv and model, with your name and therefore the warranty they have included if any.LCD tv's are one of the most unsupported mass marketing consumer items that are being dumped on the US market. I think you have Blown capacitors, or more likely a problem with the power board, typically this requires soldering new capacitors onto the power board after unsoldering the blow ones and if this is all the problem is the issue will disappear, if there is an issue with a transformer, or some diode or computer chip then you might as well replace the whole power board. the capacitor issue is no big deal if you can get an electronics service center to look at the problem.
