Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

I smelled something burnt and a clicking noise

When the unit was on it suddenly burnt something and then is sounded like it was powering on and off. It just kept clicking and no picture. Then it stopped clicking and the picture now has three images overlapping each other in green, yellow and red. Is this a common problem and if so I hope it's not too expensive. Thanks for your help

Re: I smelled something burnt and a clicking noise

This is a Common problem, you have shorted convergence amplifiers, some of these have a small board that is mounted behind the CRT's with a red plug/blue wire, these are incredibly easy to replace, some samsungs have the convergence circuits mounted on two tall heatsinks on a big board with the high voltage transformer (has 3 big red leads comming out of it) and requires alot more work to replace, if you are uncertian I would call the repair man, you can look to spend around $350-500 I would suspect, if you call someone might ask what convergence board replacement would cost.

I have no pic or sound except a chirping noise , sounds like a cricket , LOL , timer light stays red , there was a odor , like a burnt smell

Hello. The chirping probably indicates a shorted transistor or diode, and the burnt smell usually indicates a blown capacitor or a burnt resistor, or multiple damaged parts. I would have to see the TV to be of any further assistance. Sorry I couldn't be more helpful. Good luck.

Screen is black

sounds like it was enough to pop something in the tv, smell the back of the tv smell if anything smells burnt or hot. unplug the tv and let stand for about a hour unplugged then trying it again but if it does smell chances are you will have to see if your still under warrenty and have the unit replaced.

TV has no picture or sound. Was working fine then suddenly went black. Slight smell or something burning and just a clicking sound inside TV now. Any thoughts?

if it is 46F500 UNPLUG SET and remove back cover--on far right side as you look from the back you should see either two smaller or one very large heat sink with fins--the set listed has either one or two STK-392-110 OR STK-392-150 CONVERGENCE CHIPS.

Near them you will see about 12 resistors--look to see if any are burnt or slightly discolored in the middle---you have to look close at them--they can all be checked like checking a fuse--no reading and one is gone----

Point here is if any are bad or smoked--one of the convergence chips got them----the only other way to prove or disprove this is to get at the chips and un-solder all 18 pins on each chip--if set turns on--one is bad and BOTH NEED to be replaced along with any bad resistors--if you smelled something--something toasted--- these resistors are FLAMEPROOF or metal oxide--they will not catch on fire, just pop and go instantly.

Let me know what you find and I will help you--I am here to help people---If this helps you rate this solution as I do this here for free.

Sony KP-41S3U

Good Day;
On that model look for a small yellow cap, half the size of coin, dime. LOOK very closely and you will see a small burnt spot on the cap. The TV uses about 4 of them, they are 120/110 @ 2 kv. There are located in the high voltage circuit.
This the most common, it could be flyback or HV devider.
Good Luck and Day, big irish.
LET ME know.

No power all of a sudden

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

for poor convergence check RK42 for open circuit.
