Possibly due to the main inverter panel, take the numbers off and price one up they vary from £50 upwards

SOURCE: Continuous click noise like its trying to turn on but will not.

I have done some research and found a notorious cap and diode problem with this set. The two 4700uf caps (C14113 and C14115) on the DM1 power board (the board to the left of the sat. box when you look at the set from the back) are under rated and will eventually fail. When these caps fail they tend to take out diode CR14105. This may be your problem. If it is, you can replace the caps with 4700uf 25V 105c and the same as original diode.

SOURCE: My samsung tv turns on and off repeatedly at

Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

The tv wont turn on but keeps turning on and off byitself continuosly but not suceeding


Good day!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Unit model D-C350/XSA only opens region 4 need to also to open region 2 DVD's


Hi there,

When I was with Samsung NZ, the following was how we multizoned our DVD (Region 4) players:
1. Turn on your player, but ensure no disc in machine - screen should show "No Disc"
2. Turn on your TV and select your DVD input (as if you were to watch your DVD).

Using your factory supplied remote, press the following buttons:

3. Press the Repeat (or Repeat A-B) button
4. Press the following button sequence: 7, 6, 8, 8, 4, 9 (you should see the number '9' appear on screen - this means 'Region Free').
5. Press the Open/Close button (to open the tray)
6. Press the Open/Close button again (to close the tray)
7. Press Power OFF (to shut down your DVD player)
8. Press Power ON (to turn on your DVD player)
9. Insert Region 2 disc and wait (up to 1min) for firmware to respond and read your disc

If this fails, try procedure again, except for Step 4: change the last number (instead of 9) to '2'.


Let me know how you get on.

Cheers,

Scott

My samsung ps42c91hdx/xsa tv wont tune in the high def channel 10. the tv can't find it. My sons tvs are picking it up so it cant be the signal.


go to MENU, SETUP,

There you can reset to factory settings. After you set the clock and date, it will ask to scan for all active channels and it will block out the channels it does not find a signal for. Let it complete this task (20 minutes). It asks you for the type of signal but just leave the STD setting for both options before starting the channel finding routine.

When complete, go to channel 10 to see what show is on (low def version). then click down to channel 2 and then push the channel down button several times again to try and find the HD version of that show. (HD channels are high-number channels that are easiest to get to by scrolling below channel 2. Most will have a hyphan in the channel name (e.g. 93-2; 94-1, 94-2, ...).

If your TV goes directly to a 2-digit channel, they you do not have an HD tuner in your set. I doubt that is true so I think you will find what you need.

Let me know if it doesn't work.

Tv just turns itself off and then starts clicking like its trying to turn on and off


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps
