Question about Televison & Video

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):
ad66cdc.jpg
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.

SOURCE: no picture on my tv, a polaroid flm-1507

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.

No picture


Sounds like you have a backlight problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flashlight on the screen. If you see a faint picture you have a backlight fault. It could be as simple as a bad capacitor in the power supply, or a faulty inverter board, or in rare cases a bad backlamp.

Can the lamp be replaced for a Polaroid TLX03210B


You likely have a LCD set there which may likely use a back light inside to light the image, get the room as dark as you can and with a flashlight illuminate the screen from a angle, with set on if you can see the faint image on the screen of the program you have a Backlight issue'

1. Voltage not there or not being switched on for backlight.

2. Actual back light bad.

If the image can be seen with a flashlight one of the above is the issue and your "picture will appear very faintly" also suggests this.

No volume on the cable tv setting?


Does the set have a earphone jack? if dirty or damaged it will cut the TV sound out---about the only other possible reason is a audio problem in the TV itself---if possible put ear up to speaker to see if any sound or buzz is heard.

Hi i have fla-323b it will not turn on but the light on the mother board is on the fuse is ok would it be z9 thank you ab


Can you get daylight on it? It sounds like the backlight is not working; if you can get some daylight on the screen when there should be a picture, can you see (very very very faintly) and picture there?

You use daylight as it has some distinct light polarisation and so the lcd's twisting affects the light and you can see if the LCD is ok or not.

If the backlight bulb is gone then it needs replacing; quite costly I'm afraid.

Don't know that it's worth the money, but here's a source for a replacement inverter board (powers the fluorescent tube back light that provides 'brightness'). Manufacturer/designers of screen and back light power circuit, not Polaroid, are at fault . Screen and back light are used in equipment made by others as well, and all suffer same design deficiency :

...the answer is correct...the power inverter for the cathode backlight is a complete failure with these Polaroid models.  Polaroid should really step up and fix a known problem.  Mine was purchased as a gift and not opened until the worthless 3 month warranty expired.  Didn't work out of the box!!!! I will never purchase a Polaroid product again since they obviously don't care about the consumer and sell a product that they know was defective.
