Question about Panasonic CT-35SF23 35" TV

Open Question

Subwoofer buzzing I have a Sony STR D560Z and when I bought this 12 years ago, I didn't have a subwoofer to plug in. Everything worked fine. Two years later, I upgraded my surround sound and added the rear, center channels, and of course a Cerwin Vega 12 inch powered subwoofer. From the beginning, the sub would buzz using the cord provided from CV. So instead of using the cord, I just ran the right and left speakers through the sub and ran the right and left front speakers from the sub and everything was hunky dory. When the CV Sub fried its card, I bought a lower priced 8 inch subwoofer from JVC. It has no other means of plugging it in except the cord provided. I plug it in and it buzzes too. I can fold the cord over itself and the buzzing stops and the sub works normally, but as soon as I release it, it starts buzzing again. The CV sub did this too so I know it is not subwoofer. I can plug the cord into any other audio out and it works without problem. Is there a cord provided by Sony that will prevent this or is the problem the receiver?

I don't know the age of your set but I've found some Panasonics with a loose connection on the heat sink (an aluminum plate standing vertically on the circuit board) of the regulator IC (chip). The IC gets its ground through the heatsink. If the ground is open the power supply puts out too much voltage and causes the set to go into shut down. I've found this problem several times.

Hi Rokko, that part number brings up a video board assembly. Is this what you expected... Smoked electronics associated with storm related power surge can mean extensive problems in more than one area... what symptoms are you experiencing with the gear?

Have you got cover in your insurance policy... and many electricity companies are bound by law to maintain supply within a certain percentage, and even though it was a storm that caused the problem... the power company delivered it to you... and can be sued(or at least threatened) for damages if they don't get straight up and just sort out the problem for you. Is worth looking into:)

regards
Graeme

No Display, no sound- not working, showing dead. But input Power is ok. Picture tube filamment not getting power. model sony KV-2192M3


Hello
Check the input fuse first. If it is blown, there will be some short inside the power regulator circuit. Usually Sony sets uses STR regulated power supply. You can see this STR, and Ic, screwed onto a heatsink. Replace it with a same type and number. Before replacing the STR, check the diodes used in that section for damage, mainlu zener diodes. They might get shorted along the blowing of the STR. Check that section throughly before resoldering the new STR.
If any further assistance you needs, get me through Fixya. Ok.

Have a sony trinitron tv which turns off automatically and sporadically on average every 15 minutes


Hello
Most of the sony Tv power supplys are based on STR type regulators. Regulation of an STR is very accurate and if any overload inside the ciruit board of the TV, will be sensed by the STR and will shut off all the supply to the system itself. From your complaint we understands that there is some sort of short, not a direct short, is in your tv. Usually it may related to horizontal output transistor. At first it will work fine, but as time pass on, it will get over heated, passes more current, and place a short like circustance to the power supply rail itself, and as described above, STR will sense it and will shut down the system. After some time, say after 10 or 15 minutes, after the heat generated has gone off, the TV will again switch on, and the cycle will be repeated. You just call a technican and keep this in mind, and ask him to repair the same.

Speakers


Just about any speakers should work fine. They would sound best if pair of same model.

If it has a headphone jack, just plug in a pair of powered computer speakers (the usual kind). Spend a little more and get a subwoofer and better sound all around. Figure $10 to $100 per set.

Buzzing noise


Fly back transformer will cause a buzzing sound like this. Really up to you how bad it bothers you it can be fixed but it will cost a couple hundred dollars. If you can solder you can put it in yourself but the flyyback will still cost a little bit of money.

TV won't turn on.


The buzzing sound could be due to either a bad filter capacitor in the power supply or a shorted component further down the line keeping the power supply from running at the correct frequency.

Goodmans 1430R TV (bought 10 years ago) switched off in middle of program by itself and no longer works.


Oh come on man the sets tired!!!LOL no really you got plenty of use out of this bugger. Your problem sounds like something opened in the power supply and since the sets all solid state theres no user serviceable parts inside them. If you really wanted to put cash into a 10 year old set for an estimate/? i would not . But if you like the set go for it. Good luck
