Question about Projection Televisions

Open Question

I have a Polaroid FDM-0715 under-counter set. The backlight on the LCD screen seems to be inoperative, sound is OK, and I can see a faint picture when I shine a flashlight at the screen. Where can I order a replacement backlight? I also cannot find any Polaroid authorized repair centers, it seems as if Polaroid has no support/repair infrastructure Thanx....Ruud hartog (ruudh@aol.com)

1. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.

2. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

Hope that helps...Should you have any further questions, please feel free to post them here.

SOURCE: philips 32" lcd hdtv. HDTV no longer displays, but sound still ok

I reset the comcast cablebox. I totally unplugged the cablebox for 20 seconds and then plugged it back in. Turned on both the cablebox and the tv and the HDTV channels operated correctly.

If you are still getting Sound, then most likely the bulb has burned out, (If you have a Rear Projection set). If it is a flat panel LCD, then the problem could be the electronics that power the fluorescent bulbs in the back of the LCD panel. Those bulbs will last about 10 years or so, but the electronics, (like the balast & amplifier), could have died. Please check your Cust Service Manual that came with the set & look for your symptoms, and that should help. Either way, a qualified TV tech will need to check it out.

SOURCE: samsung lcd TV five years old, screen suddenly went black

In order to properly provide you with guidance, we need some hint about the problem. Can you describe the symptoms? Is the set dead? Are there any blinking status lights?

Thanks,
Dan

I have just turned my finlux tv on and there is no picture only sound please help


Since not a brand or model number listed : If its a LCD set get a flashlight and make the room very dark with the set on. Shine the light on the screen at an angle to see if you see a faint image of the picture on the screen.

for more help--model and brand are needed.

The screen goes black. On every channel. Sound is perfect. Is the TV dead


Ok---let me describe something and you tell me if your case: Set comes on and has audio--after 2-5 minutes if you look closely at the screen do you see a odd and faint band of noise top to bottom and to the right of the center of the screen?

It takes a couple minutes and will be faint and easy to miss.

Let me know what you see.

Sound but no picture


Is this an LCD set? if so...

Try the set with the inverter unplugged and if you get sound its almost certainly the inverter. You might also see a very dark picture as the screen will be working but the backlight wont be lit.

Be very carefull with the inverter, theres some high voltages there.

If its not LCD I think we would need to know the model.
