Question about Samsung LNT3242H Television

1 Answer

HI I have a 3 yr old Samsung LN3242 LCD Tv. Last night the picture on the tv went out and a high pitched squeal started. By the time I got up to unplug the tv smoke was coming out the back. I unplugged it for a few minutes and when I tried plugging it back in there was no power, not even a red light on the front on switch. I opened it up today to check the powerboard to see if I could tell what had burnt out but I cant. I saw a diagram you had posted of my powerboard and had 2 questions. First any idea how to fix my problem?? Second, when I detached the conections to the powerboard I forgot where I took one out. On the top right of this diagram there are 2 slots, on labelled A and one labelled S, which one should I connect to? Thanks

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: Plasma TV-power light does not come on

Hello!

most probably the fuse inside the circuit blown out, You should open the back of the tv to become circuit board visible. But this hard when novice do it.

To be sure that everything will be alright i would rather suggest you to bring the tv to the nearest service center. maybe warranty work for that.

best regards,melnavz

High pitched squeal


Hi...

Does the squeal come from the TV cabinet or the speaker?
If from the cabinet , it's most likely the Horizontal high-voltage section of the set.
Find someone that's good with hand tools,unplug the set from the wall outlet, let it sit for a good 30 minutes.
have someone open up the back of the set and dust out and vacuum out any dust from inside the set.
Put back together and try it out.

Stopped working and squealing sound


Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.

High pitched squeal from TV


Get a small wood/plastic stick and touch the different coils/transformers to see which one is the cause. Replace part or if the part doesn't run hot, use a small amount of hot melt to quiet. Don't completely encapsulate in glue, don't want to create any hazards.

No Picture


Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
