Wharfedale tv settings


By default, the TV stores memory of last settings in its memory ic, when you switch off. By modifying the input devices, you have increased the number of settings to be stored, which might be beyond its capacity to store and it switches to default settings. Try resetting to the desired input and locking the settings.

I have a panasonic plasma tv model TH42pZ80u series i think. as soon as i switch it on all the electricity on my house top floor switches off from the main electricity socket. dont know what to do!


There is a direct short circuit inside the power outlet, or in the mains cord of the TV. Switch off and remove the plug of the TV and just switch on the power outlet to make sure whether that is the culprit. If you have a multimeter, test the TV cord pins for short between phase and neutral and earth. If you notice short, this may need attention by a qualified service technician.

This is a protection switching off due to defects in the secondary power section like H-out or Vertical. This might require attention by a qualified service technician.

I have a 32" CRT Sylvania Tv that won't turn


Hello
If the TV doesn't turn ON ata all, it is surely due to some fault with its power supply regulator section. You haven't given any otehr details of your tV, than it is only a 32 inch CRT Sylvanial Tv. No model number; so I only can provide you a solution in general.
Check the ON-OFF switch for its contact. Normally, TVs uses DPST type switches [Double Pole Single Throw]. If any one contact amoung them have any problem with its internal contacts, the set won't switch ON. If the switch is OK, come towards the power regulator section circuit board, and check whether the fuse has blown out or not. If it has blown out, replace it with same type and ampere rating. Never use higher ampere rating than specified. The ampere rating will be maiked either on the rims of the fuse, or at the printed circuit board, just under the fuse. After repalcing the fuse, switch ON the TV and see whether it works well or the replaced fuse blows up as soon as you switch ON the set. If the repalced switch burns out as soon as you switch ON the set, the power supply section has damaged [shorted components in it]; and should be replaced.
Normally for LCD TVs it will be good to replace the power supply as card basis. This power regulator card can be bought from most of the electronic spare part shops at your town, orby the authorised service center for Sylvania at your town. If you may have given its model number, I could send you the picture of the power card of your TV. OK.

My phillips tv audio doesn't work well


This problem might be related to a bad control board that controls the Audio and Video and other functions. It costs $180.00 to replace. Not worth fixing

Volume turns down


Enasni,
It's probably a tact switch problem, something we call in the industry awindex syndrome. The tact switches, depending on the ones effected, can turn the tv on/off by itself, channel +/- at will or in your case control the volume.
Tact switches are not expensive to replace but a bit difficult to get to if you're not trained. They are at the very front of the board - looking from the back - and some disassembly may be necessary to take the main board out.
A reputable shop wouldn't charge much do fix this problem, switches are about a dollar a piece.
Good Luck
Bill
