My lg tv picture is ok but a shhhhh sound on eht

5 supply Volt missing in IC TDA 11105ps/N3 used in beston tv

i hope your TV is getting ''off '' by itself when you are trying to turn ''on'' - not when you are watching TV...........then following is the situation ..........IF LED IS BLINKING then---- usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ..........IF LED IS ALSO OFF then on main board in power section area some component is deffective ... MAIN BOARD SHOULD BE CHECKED COMPLETELY........ so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore.....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact samsung service centre.........

Hello
The power supply section inside your TV is not working. It may be due to a blown fuse, or its inverter secion itself. You have to open your TV to detect and repair the fault. If you are aware in electronics, open it, and check the fuse first. If it is found blown up, replace a new one with same rating. Do not use an other rated fuse, as it may damage more components, if there is a fault inside the circuit section of the power inverter board. If the newly inserted fuse also blow out, as you switch ON the TV, never put any fuse there, and it must be due to some fault to that section, should be checked well. Without any reason, a fuse won't blow up you see. We must find out the reason for that and rectfy it before replacing an other fuse in place. Normally, rectifer diodes, inverter device, a transistor or an STR, whatever may be the case, should check with its schematic diagram, and replace them. Whe power reguator [inverter] side get a fault, it will cause more component in that section to be out of order. So you have to check each component on that section before replacing and switch ON the TV.
If you have a sound knoledge and measuring instruments with you, you can do it by yoursef at home. If not, get it repaired with an experienced service technician. OK.

it is problem high voltage unite problem (EHT) change it then solve your problem

EHT OK BUT NOT FUCTION NOLIGHT AND NO SOUND NO DISPLY

blown resistor (42ohm) replaced this and it imediately blew it clearly shows that there is a short circuit in your tv. if you are a tech person please proceed as follows. 1 isolate power supply from hor.output section. 2 now check power supply section.i.e. switching tran., cap..diode etc. 3 if it becomes ok check power supply output. 4 if output is ok then check hor. output section.i.e. h.out tr.,cap& diode in eht winding. 5 check print near eht. 6 at finally eht. 7 see every thing is normal now. now reconnect power to hor.section. put on tv. good luck.

My LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all, the picture was suddenly reduced to a thin vertical line down the centre of the screen and an awful smell seemed to come from the tv There is a short ckt in your tv in horl. section. 1 isolate power from horizontal section. 2 check for normal output from power supply. 3 check parts in horl output section a hor.output transistor b diode & cap in h/output trnsformerckt. c check for print. d if all are ok check for eht transformer. e if every thing becomes then reconnect hor output section supply. f put on the set.

ticking sound (like a Watch) coming from around the Flyback Transformer but I don't see a spark is called EHT voltage . if eht voltage is ok 1 check filament is glowing or not if it is ok check voltages on crt. 2 if it is ok check luminance section in chroma section. if filament is not glowing check for low eht due to hor section check power supply output also. good luck
