There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

    The ticking sound is from the power supply turning on and off because it sensing overload or false sensing due to bad power supply itself. You need to disconect the connector that is suppling the power to the inverter board, then turn it on to see if you can get the sound but no picture, if you do, then it can be the inverter board is shorted. Look for the connector on the power supply that label with 24v. Pictures?

    The connector with Black and Yellow should have 5VDC on the Yellow (meter positive lead to the YELLOW wire, meter black negative to the metal chassis of the TV), the other connector with RED should be 24vdc and Black wire (negative), the other connector with black (hot/line) and white (neutral) are for 120vac incoming line voltage- be real careful here. The picture on the left side show the inveter board whic is under the grilled cover with a bunch of pink and white wires attached to the left side, you should be able to remove the grill and then remove the connector on the right side of the inverter board. Then check to see if yoo voltage reading on the red wires of the power supply board. Can you also give me the printed numbers on the power supply board itself?

  • Bud Martin
    Bud Martin Dec 03, 2009

    I Google the number you give me '782.L32U25-200C' is the correct number for the power supply. You can get the replacement here:

    http://www.discount-merchant.com/We-prov... but they are 0 stock right now. Somebody in UK also selling repair kit: http://www.chsinteractive.co.uk/electric...

    So it must be common problem with this power supply to fail. Are you in thge US? My email:[email protected], I am in California. SF Bay AREA.

How to reset tv

hi Tracie,
is the set making a clicking noise?
is the power light flashing on the front?
or no power light at all just dead?
if the set is just dead, just put your ear to the back vents can you hear like a very faint screaming noise and can you smell and burning in the vent?
if so it just could be capacitors on the power board.
if its clicking the that will need a service kit on the power supply board.
if the power led is flashing then you will need to count how many flashers from start to finish when you first turn set on.
hope this helps.

Plasma tv picture not coming on and power light flashing

Yes, you have power supply issue.
the power on circuit is malfunctioning and the flashes is the indication that the voltage levels for the power on regulation is not correct therefore shut down to protect the circuit from further damage. You TV unit needs servicing by an plasma TV specialist.
Also check to see if you do not have the TV in sleep or hibernation mode.

I changed the bulb in my tv and it was working for a few days. Now I get audio but there is a wierd electrical clicking noise which made me think the new bulb broke but I still have a green light on the...

In this case there are two possibilities of what part is the one causing the issue, it coul be a ballast because of the clicking sound that caused the tv to shut off, and that buzzin sound is for your color wheel that it might not be working anymore, discountdashmerchantdotcom free troubleshoot

I have a rca 32v343t atc010a and when i turn it on the power light comes on and the tv makes a noise like its coming on but then theres no picture or sound. I would like to finde out whats causing this to...

It sounds like the High voltage transformer has gone out. If you open the back of the tv and look on the right side, you will see a large (4 - 5 inch) black cylinder with a large wire coming out of the top. without touching anything, look and see if it is cracked.

TH-42PX60U red light blinks 10 times wont come on

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

Wierd sound when I switch on the TV

Your TV may something arcing inside of it. Maybe a loose connection. Since it is probably under warranty you should get in touch with the dealer where you purchased it. Perhaps you can get the whole TV replaced. Stargazer
