Could be an issue with the convergence IC, which will need replacing.

It could also be faulty capacitors that cause this problem. You will have to open the back panel and take a look. Youcan make out which are faulty, because their caps will be swollen on top.Here's a sample pic of a bust capacitor (not same model):

Check the specifications of the faulty capacitors, and get the replacementsfrom your local electronics shop. If you are comfortable with this, you can usea 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 todo this, try to get a friend who knows how to do this kinda stuff do it foryou, or get a qualified technician. Warning: If you do nothave a background in electronics repair, or are inexperienced, get a qualifiedtechnician to do it for you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

Hope that helps!

Smart T.V Sumsung Got Stuck


It sounds that your TVs' timer function is set to 'ON' for 15 minutes time. Check it, and make it 'Off'. Refer its user manual for details.

If there is sound, no doubt, its signal input is OK. The problem must be to your Tv itself. If the LVDS cable, the cable that connects between the T'Con board and LCD panel have a loose contact, this type of faultcan occur. Re-seat this cable once, and check. If you wish to get more details, surf the following link. There are over two thousand and four hundred posts. All are related to television and other domestic electronic equipment service help.

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?


If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.
