Sounds like your picture tube or bulb is going out. It depends on what kind of tv ( rp, lcd, plasma) it could also be a component issue.

Sony pfm-42x1 flickering screen when turning tv on


OKAY I found the Problem!! Bad Caps Compositors. I Proved this in 2 ways. First I took off the Back(always make sure the TV is UNPLUG) In the photo above I put my finger on the capacitors. I found some that where NOT FLAT ON TOP(You can kinda see in the photo too). I could feel a little nipple on top.(Some times you can see if their busted open but not in this case) so I felt them and the bottom right and top left area in red in the photo where not flat. I took my dryer(My wife really) and warmed them up for about 2 minuets each then another minuet rotating back then forth. I leaned the t.v. up to lean on the frame and plug it in. I continued warming the capacitors up and in about 2 Min the T.V. has stop blinking. Much better then the 20-30 min. So the hunt for the Capacitors is on. It will be some work to get the boards out. If everything is done delicately The Soldor job is easy for me. I am going to buy the 8 but replace 1 board at a time until the TV works and put the other on the side for next time or put them up on E-bay. I hope this helped Please like if this helped you. ea0a96a3-fb82-4ec0-89f4-76b4080e9c6e.jpg 1b190ebd-5d69-4553-a009-840d29ab4c87.jpg ab9b51d0-6e1d-4cce-b822-e80d0fde9163.jpg

My Marshall mg100dfx has just recently began to schreech and buzz as soon as I power it on. No instrument plugged in. No previous buzzing or unusual sounds. Now all of a sudden when I hit the power switch...


It sounds like a bad capacitor in the item, the value changes as it warms up. I would suggest pre-warm up before the public arrives because this may take time to find the problem, and then you can tackle it or bring it to a technician.

If a tv is left outside (on a porche), how does the cold tempeture affect the TV .


Hi,

There are two problems with leaving a TV out in the cold:

1. If the TV was used outside it will be warmer than the air temperature. This causes moisture from the air to condense on the warm/hot surfaces of the TV - including the internal components. Water conducts electricity so if the TV is switched on and there is water (condensation) on the internal components, it's more than likely that something will short and cause serious damage to the TV.

2. Some components inside a TV are very sensitive to sudden dramatic changes in temperature. If a TV is very cold and you switch it on, the sudden increase in temperature of electricity flowing through cold components can damage them.

Sudden dramatic increases or decreases in temperature damage many materials. If you take a glass dish from the freezer and immerse it in hot water, it will probably fracture and break. If you allow the glass to warm up slowly, it doesn't break. This is exactly what happens to components in a TV if they are very cold and you switch the TV on.

When buying a new TV or any electrical appliance, it is always good practice to take it out of the box and allow it to reach room temperature before installing it.

Sony KV32s45 sudden failure


I really have to say there is no miracle cure for TV's I have 20years of experience in fixing TV's I don't suggest for you to try to fix this as TV's run on high voltage and you could kill yourself.

If you really cannot find a tech to check it for you the only thing you can try is to check for a broken fuse.

You Must Take Great Caution.

If you are a person that like to take things apart you may try to take the back off .
Start by disconnect the power cable and follow the main power cable inside , normally it goes where the main switch is located and there you should find a Time Fuse normally the value is around 2.5 amps T for time it should say on circuit board & on fuse.Check for a faulty fuse.If faulty replace with the same type fuse and before you plug it in put back all covers than you may try to put on TV.

If fuse is good than fit back cover and take to a professional.
