Is there a main power switch to a lcd Philips TV


Yes. There is a main power switch at its front panel. Refer its user manual for details. If it cannot be turned ON by this switch, the main power supply regulator board inside the TV is faulty, and should be replaced. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

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.

I have a philips 37" flat screen TV, when I switch


hi,
There is problem with the back light of your tv. In LCD tvs CCFL are used as back light to give light to independant pixels. CCLF lamps required high voltage to light. This high voltage is provided by the inverter board inside ths tv. If any one of the chopper transformer (high voltage transformer) have some problem then the inverter will shuts off itself preventing damges to the power supply.

You have to check the 24V from the power supply. If its ok the you have to check the inverter board.if avilabe replace the same. if you are not able to do the same i will prefer to consult some one experienced in it. Back light inverter board will look like one in the picture.

26la30q wont turn on


Hi
You have to start checkin from its main ON/OFF switch itself. If the switch have any contact contact trouble, the set will not turn On, even though you hear the click sound from the switch. If switch is Ok, then you have to come to the power supply regulator board. It can be easly recogonized the powe supply regulator boad. The main supply line will go straight to it. There will be more that 5 or mor secondary voltages from it, according to Tv model. These secondary wupplies will energzed only after the power supply switching circuit work properly.
Ther is a fuse [ a cartridge type; replaceable]. Check the fuse first. If it has blown; be carefull when you replace it; because there must be some reason for the blowing of that fuse. It is really a protection device. Before replacing it, you have to check the entire power supply board for some short circuit. If you have sound knoledge in repairing Switched Mode Power Supply [SMPS]; just proceed. Otherwise get it repaired by any experienced service technican or by authorised service center for Proscan. OK.

Bad power supply or backlight inverter.

If the backlight is not turning on, you should be able to see the lcd image by shining a bright flashlight at the screen.

Backlight inverters are loud, so you can hear them operating (high pitched whine) and if the backlight is coming on, you can see white light leaking around the edge of the screen, and even a little inside the cabinet.

Philips are legendary for having power supplies that fail due to bad capacitors, so that could be the culprit as well.
