    How can I tell which board is the D board. I assume it's the one that the power from the wall goes into? R8051(resistor I know what that one looks like), IC 8005(Is this the one that looks like a black box mounted onto a metal grill with white magnesium) Q8014 and Q8015(No ideas on this one can you give me a description). Sorry about this but I'm with the Marine detachment in Havana, Cuba and there is no service provider to take this to and being an Avionicsmen on helicopters I decided to give it a shot at fixing it. thanx

  • DetCmdr Apr 23, 2008

    We checked Q8013 and Q8014. They both metered the same so we are thinking it is good. R8051 metered 340K ohms and IC 8005 looked ok. Which component do you suggest changing? The resistor and the IC unit or just the resistor?

High voltage protection. Either transistor Q8014 04 Q 8013 is shorted along with R8051 on the D board or IC 8005 is defective on the D board. Let me know if you need more assistance

I have this same problem with my KDP-65WS550. The only difference is it seemed to be intermitten till just recently. Now it only comes on for a few seconds with sound and no picture. It then shuts offs and blinks the standby indicator. After a few blinks it shuts off completly.

I had the same problem and changed IC8002 (MCZ3001DA) and IC8005 (TL1431CZ) on the "D" board and this resolved the problem.

I wonder if there is anyone that can tell me why Haier 32in.flat screen tv just shuts down and the is still on but no sound or picture is showing could someone tell me what the problem is ?

Sounds like the power supply board is going out on it. I'm a t.v. repairman and many times, I just replace the capacitors on the power supply board and they work great. If you aren't qualified do not attempt this yourself. High voltage will kill. Not worth it, take it into a shop.

Lg 42 no power

If its dead and no sound what so ever its usually the power board and if so you can usually get replacement boards by contacting the people over at if its not listed they most likely still have it and you can check by hitting the contact us button on their website and letting them know your model number and symptoms and a tech for your model will respond quickly to your problem for free as long as you include your model number and symptoms of the set.

Power comes on but no picture

I have the same problem. After power on I just get a blue screen and no sound.

I can get a piture and sound if i do the following.

Leave the TV on for a minute or two then unplug the power while still on. Plug back in and power on. I begin to get sound, repeat and then I get a picture for a few moments then blue again. Repeat and then I get constant picture with defunct colors. I then use the remote to power off and back on an color corrects. sometimes have to repeat this as well. Sometimes it takes unplugging, replugging, and powering on up to five times before i can sit down to watch tv.

Have picture lose picture tv turns off and on

the lamp has a life cicle. if yours is been used a lot. then the lamp has to be changed. when the tv cannot turn on steady and gets off imm. the computer inside the tv tries to turn off the set but the lamp charges again and the micro tends to keep working. the first step to take in this tv is to change the lamp to eliminate this common source of problems

TV has power, but picture or sound will not come on.

It sounds like something in the set has failed. These newer TV's have shut down circuits that won't let the set come on if there is a short or excessive voltage somewhere in the set. Most failures in TV's occur at the moment the set is turned on.
