Wait at least 30 seconds after pushing the power button; plasma TVs tend to take a while to turn on (mine definitely does!). If this doesn't work, unplug it and plug it back in. If this still doesn't work, I'm sorry, but I'm out of ideas.

Standby light keeps blinking. tv wont turn on


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

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...


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...

Plasma model ciwp4206 made by funai (inside samsung plasma)doesnt turn on, light blinks 9 times then nothing. thanks in advance


Remove diodes D2500 and D2501 (which are only protection, making the TV goes to standby instead of powering on) from the main power supply board. If the light does turn to a green one instead of going back to standby and you have the sound but no image, it should be the same problem as I had, which seems to be frequent with these Funai piece of junk.

You need to replace the ceramic capacitor C2258 on the main power supply board, it should be the faulty part as it was on mine. This capacitor is near an aluminium heatsink and was slightly burnt.

Here are the specs of that part from the service manual:
C2258 CAP CERAMIC HV 3300pF 2KV R K

As I didn't find a capacitor with these specs, I put two capacitors in parallel and it works fine now. Good luck!
