Philips tv 28pw6506

Hi my tv turns on then goes back to standby a few seconds after it turns on. This happens several times untill it stays on. Also the screen takes a while to fill out the sides go wavy but when it turns on fully it is fine. I took the boards out and can no lose or bad connections, plus i blew the dust out while i was there. I did read that it is the capacator on these sometimes the y dont like to go to 12v when they switch on.?  I have done an ellectronics coarse so i do know how to solder and yes i am fully aware that some of the capactors hold there charge after the set is off. Any help as to what is the faulty part and its number or position on the board and the currewnt it should be putting out would be most usefull

 Regards  Charlie

    Thanks for that TVboy I will try it as soon as i can get the bits, i was going down the road of replacing the bc337-25 (2off) ref 7463 @ 7461. I take it that you mean the capacitor at ref 2455 which is 47uf 25v. Thanks for your input and i will give you top marks if you are right, ps I think you are spot on, thanks!

    My TV kept going off as well, when I hit the standby button a few times it would go on again as the picture got wider, until it eventually would stay on - now it's off permanantly. Very disappointed at the TV being less than two years old, and it seems the tube is already gone on it. I'm not an electrician so cannot repair myself.....is it worth going to repair place, or just dump it vowing not to buy Phillips again?

Sony KDL-46z4100 standby light blinking 12 time with few seconds gap continiously


12 blinks of standby light indicates 'Scanrate error'. You must have thorough knowledge in electronics to proceed. Actually, this is not a user repairable fault. it is very skilled work.

Hi my samsung crt tv come up on start up but couldn't stay for more than few seconds before it goes standby. I've tried to check settings but could not even get anywhere before it goes back to standby


Whenever a television starts doing this the motherboard/main board and or power supply is usually at fault. The power supply can usually be rebuilt for around $150 depending upon the knowledge and skill of your local television repair shop. To replace the parts is usally more expensive then it would be to purchase another television ($300 and up). Are you sure this is the model number of your television because this model number is not for a CRT television. For troubleshooting you can unplug it overnight to try and power cycle it but it sounds like your problem is beyond doing any type of power cycle to get the television back going again. It would need the repair shop or to be discarded for another.

My magnavox 42mf438b lcd tv will be fine for about 10 minutes when i turn it on, then the screen goes completely black but it still has sound. it stays like this even if i turn it off and back on. i can...


that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
