KV-XJ29M50 29" TV-Loud thumping sound on startup

I bought this Sony 29" TV Brand Nw about 2.5 years back and it has been working fine. Recently, it has started to give this thumping noise that comes from inside the cabinet and it comes whenever I turn it ON. Also, the picture sometimes becomes grainy and i thought it was some interference but now I have discovered that when picture becomes grainy, if i restart the TV it becomes clear again. This noise is really annoying and the technicians here in NZ thinks normal,though no one has physically inspected the unit, I have spoken to them on the fone. Please advise.

    thanks jomaru, but why is is that it has suddenly started giving this problem and why don't other sets that i went and saw in stores give the same nows, is there a way to get rid of it. I have just found the manual and noticed this in the troubleshooting section - 'A boom sound is heard when the tv is turned on."
    Possible Cause - "The TV's demagnetizing function is working. This does not indicate a malfunction."

    Thanks

Symptoms are not related,what you hear is the high voltage turning on and that is normal if it only does it for less than a second,the grainy picture might be intermitant,dont turn it off,when the picture is grainy tap the side of the set to see if it racts and if it does you know you have a loose conection.This could be outside because of a loose ground on tha cable or inside in the tuner.

    You are correct,the noise is noticeable more in Sony sets tha any other brand but is still consider normal,the description the manufacture gave you is their way to tell is not a problem.Is good it only happens when is turn on because is really no way to get rid of it.There is a way by disconecting the dimagnetizer but that will give you color problems and that is not good.

Sony KV-32S45 turns on at first, than blinks out, still sound


I would look for intermitent solder connections on the small horizonal driver transformer as well as other HV Componets.(HV Transformer etc.) Also solder up the Vetical output IC. These have been common causes of failures. I would not use the set until these have been checked and soldered. If you don't, a massive failure of the hoizonal circuit and powersupply will occur.
Hope this helps,

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Sony KV-32FV15 TY


I have had my Sony KV-32FV15 for about 2 years now and nothing has ever gone wrong(even going through several moves.) I recently moved again and when I plugged in the TV, you can hear the sound perfectly but the screen just stays black. You can not even hear the squeal that the TV makes when comming on. Is there anything that I should initially look at to troubleshoot. I cannot afford at this time the $250 fee to repair my TV. I look forward to your input and hopefully I can get this TV working again.

Sony KV-32S40 32" TV problem


intermittent problems can usuall be liked to bad solder connections. And sony typically has some that will develop after a few years in the power supply. so check for bad sodler connections throught the main board & give a close look to the power supply & check you work after to make sure you have no shorted pins. good luck.
