Question about Televison & Video

1 Answer

Goodmans LD3250HD LCD TV: No power (TV doesn't come on & no lights lit). Fuse and plug checked and are okay. TV is out of warranty so I opened it up to see if there was anything obvious, but there are no leads loose and internal fuse (on what I assume is the PSU) is okay. There are possible signs of heat damage on a diode on the same board however. I'm assuming I need a new PSU board - am I right, and if so does anyone know where I can buy one and how much it would cost?

You can buy a replacement PSU from HERE.

But these try these troubleshooters first:

1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

4. 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.

5. 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):
Goodmans LD3250HD LCD TV: No - e209190.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.

Fuse keeps blowing on power board. It is the 3.15 amp fuse on the goodmans xpro tv


Most likely you have a short on the front side of your power supply. You will either need to have it repaired or replaced!

Tv did not turn on


Look at the power supply to see if anyhting burnt, fuse, bad capacitors. I doubt that the power cord is bad, the same size fuse should be used as the original one.

Replacement of fuses on Philips 37PF7320A 37 in. HDTV-Ready LCD


Is the fuse in the plug okay?

If the fuses are not blowing when you are turning the tv on, this suggests that the PSU primary side is okay.

Since you have opened the TV up, I would suggest probing around with a multimeter however I do not want to let you harm yourself or the TV.

Look for any:

Sounds like the power surge may have blown the fuse in the TV. You can replace the fuse and see if that works. If not, more damage to the power supply unit may have occurred.
