Question about Samsung LN-T3253H 32 in. LCD Television

1 Answer

It was working fine last night then i heard a click and the picture went dark. the power button flashed on and off in roughly 3 second intervals. no response from power button when pushed. It was taking signals from the remote: when a button was pushed the red button pulsed as it always does. It would not show any picture or sound. Unplugged for an hour, and still doing it when plugged back in. disconnected everything and tried again. Now it does not even show the flashing red light. Nothing at all when push power button.

This model is known for having issues with the power supply. Often the capacitors
have failed which may have been the click you heard but I can't be sure since I didn't hear it. The only way to know for sure which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. Over time the capacitors will change value, leak and become defective. Resistors will change value and burn. This will cause other components to become defective. This can has a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. So if it isn't under warranty, the first part if you plan to work on it yourself to replace would be the power supply unless you open it up and find find the exact problem (many times the capacitors will have a swelling top if bad or you can tell that they are burnt). If it is under warranty, then don't do anything, send it in or take it to the proper shop to be repaired. Let me know how this turns out.

10 year old Seiko Kinetic (model5M62-0B00) blue face. Last week stopped and after some shaking started again but seconds moved in 2 sec intervals for a few hours. Went OK for a week and again last night...


After 10 years it will be likely that the Kinetic capacitor will need upgrading. Your watch is designed to tick in two second intervals to tell you the power is very low. The power button will work again when it has some power to show. Yorkshire Watches www,yorkshirewatches.co.uk can do the upgrade for you if your in the UK. Give them a ring.

Have an old sony HDTV proj tv, and the picture went out last night. I heard sort of a "pop" then no picture


Pop sound shows that some thing went wrong inside TV and most probably any part got busted.
Let me know model number of your Sony TV and does its standby red light blinking? if yes, how many times it blinks between 3 seconds interval.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
