Question about LG Televison & Video

1 Answer

I have one LG 21" color tv ( MACH 4 model) and it is not getting start.It was working properly with some hissing sound but yesterday it didn't started, the LED at the front panel is glowing but TV is not getting on. I think there is some ESP power supply problem, can you please suggest which parts needs to be replaced and what is the approximate cost of these parts.

Hissing sound comes from leak EHT transformer but front LED working means your power supply is ok so you need to check horizontal out out Transister and series resitor feeding to voltage from B+ to that transistor if it's gone pls replace the EHT transformer as well
in srilanka EHT is around $5 and transistor is $1

thanks

Hi Manher
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Our tv is Samsung DLP HL-P4663W 46 in. Rear Projection HDTV-Ready Television After having our TV on for about 45 minutes it starts to make this hissing sound which starts low and gets louder and louder,...


hello
This looks like a colorwheel symptom, does the sound is like a mechanical sound? high pitch sound? winding, whirling or screeching noise ? well if this is the color wheel, what i think it is, it seems that it is not working properly when this happens the DMD board recognizes that it is not spinning at the correct RPM and turns off the Tv for sercurity reasons, so if you want to replace this yourself what i recommend you to do is to open the back of the Tv and search for the colorwheel it can have missing parts or it could be shattered or it could not spin correcty, hope this info. can help you.
