My Samsung HL-T5075S TV shuts off after being on for awhile and will not turn back on,also if you turn it off you have to wait awhile before turning it back on, I have tried unplugging it for up to one...


Hi,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
This will help.

I got a second samsung blu-ray player, having liked the first one so much. This new one has been just terrible. Presently neither the sound nor the picture will come on my Proview LCD tv, for some reason...


One thing you might want to try is hooking the player up with the Composite (yellow/white/red) output into the TV. If this gives you a picture, then try a different HDMI cable.

Hi, I just got my new Samsung 46" LCD 3-D tv


No pictures on all modes? Since it is new I would get it fixed under warranty ASAP, I hope you do not have a lemmon set. Do not open it up or it will void the warranty.

Hi - My Samsung LNT5271FX 52" LCD TV won't turn on. It just clicks over and over and over, but never turns on. What's up? A relay?


This is a capacitor problem. Several Samsung models have bad capacitors installed on the power supply boards. Samsung currently offers a recall fix for this and other models. Call Samsung direct to see if your TV qualifies for this one time fix. It is a free fix, so if the person on the other end doesn't have a clue, ask to speak to a supervisor or hang up and try again.

Tv turning on and off by itself - never fully turning on


Most likely failed capacitors in the power supply. I am currently having the same problem with my 26 month old LN46A750. Samsung has agreed to fix this as an out of warranty "courtesy repair".

Hi.

Im certain I can help you there are basically 2 fixes that spring to mind for this fault.

First fix : RESOLDER IC801S ON POWER PCB.
SEVERAL PINS ARE DRY JOINT NORMALLY.

Try the first fix before attempting the more difficult second fix.
You will need soldering iron with a tip of approx 1.6mm & 0.7mm fluxed solder.
Take notes & pictures of pcb layout plugs & sockets before unpluging anything in side the tv set.
The first fix is easy you just need to find IC801S & resolder all it legs (pins) to the pcb. To find the IC follow the mains input from the switch to the PSU board The IC will be very close.

********** IMPORTANT ENSURE TV IS UNPLUGGED FROM MAINS POWER ********
TV SETS STILL HOLD ELECTRICAL CHARGES EVEN WHEN SWITCHED OFF.
IF YOU ARE NOT CONFIDENT TO UNDERTAKE A REPAIR ON YOUR TV PLEASE GET A QUALIFIED TV TECHICIAN TO DO THE WORK FOR YOU.


Second fix : CHECK R437(1.8 OHM) RESISTOR ON DEFLECTION PCB,
IF O/C CHECK IC501, IC531, IC561 ON CRT BASES FOR SHORT CIRCUIT.
