dead set

Looks like sound circuit problem. Check ear-phone jack if one is fitted in your model. Check speaker. Check the sound I C power supply. fI you have circuit you can follow.

Otherwise search the I C no in Google and trace the faulty area. To trace the sound IC just follow the speaker wire connected to the PCB. Mostly the IC will be close to this connector or joint.

my tv control panel is locked.there is only on screen av1.it is not changed.

Check 15V line,12volts is too low.

lightning usually will damage the entire power
pcb and signal pcb.try power pcb first .this will probably repair the tv.

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

I have Philips CTV 21 PT 240B/94R. and this time a problem are when set on chenel are not stop to change only forward and bottom right side Display Scan+

Good Day;
Try these first. This TV is an oldie 1988?

POWER SUPPLY STARTS BUT WONT RUN. CHECK FOR SHORTED D909 OFF T905 PIN 17 AND/OR SHORTED IC401. (PCB-MAIN) D909 PT.# 264P521020 IC401 PT.# 272P174010 *** ( TO PREVENT REPEAT FAILURE , REMOVE T905 FROM PCB AND RE-SOLDER LEGS OF TRANSFORMER AND THEN REINSTALL) 2. POWER SUPPLY WONT RUN. CHECK FOR OPEN FOIL AT PIN 2 OF T905. (PCB-MAIN) 3. POWER SUPPLY WONT RUN. CHECK FOR OPEN R903 (220KOHM) AT PIN 3 OF IC901. (PCB-MAIN). ALSO CHECK THE VERTICAL OUT IC, LOOK IN POWER SUPPLY CIRCUIT FOR LEAKY CAPS. YOU CAN TELL BY BLACKNESS ON THE BOARDS ON THE NEGATIVE SIDE OF THE CAPS.

Good Luck, big IRISH.
