Question about Projection Televisions

1 Answer

Hi, First of all thank you in responding on my issue about my 32" LC320EM82 Emerson TV. I have acquired the service manual from NY TECH TV REPAIR, INC. I've look at it but its all wiring diagram and schematics and NO troubleshooting guide and No error code listings and their meanings. I would really and greatly apprciate if you can help me. perhaps if you can tell me just a huntz what was going on with my unit that when I powered ON remotely or by the Key, the green light blinks 4 times while blinking, I can see the wordings "DIGITAL TELEVISION" on the screen then it goes blck and back to standby mode. THank you.

    Thanks. is this the voltage reading from the inverter CBA to where the 110 V cord is connected to and then two wires (Black & Red) goes to the Power supply CBA? if so, I can read a reading of 170V DC across the wires. all the main three CBA's (Inverter CBA, Power Supply CBA and Digital Main CBA's don't show any visible bursting or bulging or burnt indications. I have chatted one of you technician and he told me to check the IC1509 or Q1505 for proper values but I don't see a proper value for reference. So I just went and order the power supply CBA which I am thinking it was the problem contributor (crossing my fingers I did the right thing). Thanks. but further inputs regarding the matter will be greatly appreciated.

You'll have to check for 12 or 24v coming out of the Power Supply first. No manufacturer gives the power supply diagram. Look for any bulged caps on the PS and replace them. Let me know...

Emerson LCD 32" TV....Model # LC320EM82....Power problem, powers up and powers right back off almost instantly....i have tried to google a solution and so many people are having the same solution but...

Okay!First i need to isolate your electrical outlet is working. Use another Video/Audio component(ex. dvd player) and plug the power cord into the TV outlet,be sure it has nothing to do with the outlet.
If the outlet is working properly,Unplug the TV power cord and wait for 1 minute before you plug it back in the outlet.Turn on the TV MANUALLY without the remote control and see if the power stays on,if not,sorry,you need it to be repair.Don't waste more time on it. If you only purchase it for few months with a reputation retailer,there is no reason NOT to call them up,cause it should be still under warranty?

Chances are its the bad capacitor issue on the power pwb, These symptoms will mimic a bad ballast.
