SOURCE: No picture and No sound

I have the same problem here with my Philips 30PF9946/37

I'm not sure this can be diagnosed as an inverter failure, unless there is a another inverter board in there I'm not aware of. The only inverter I found (actually two) in this unit is the pair of KLS300A1 inverters which drive the CCFL tubes.

Since I personally get a green power and light AND the CCFL backlight comes on, it seems unlikely that the inverters have failed.

Would love to hear from anyone who can ident the failure in these units - there's certainly a LOT of these around that have failed in exactly the same way.

SOURCE: LCD monitor produces some bursting and cracking sound. Service centre or technician address req

One of your CCFL tubes inside the monitor is broken.
This causes arcing at the connector to the powerboard of the CCFL tube.

It would of suffered a drop etc in transit for this to happen. It is extremely rare they just break like that new.

Contact your place of purchase, and they should be able to arrange a swap immediatly.

Faulty parts on PS board , bad press for Samsung

Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

Ask the dealer because this kind of repairs should be must warranty on hidden defects, a television is made for a lasting time between 4 and 6 years then yes lead free solderings and are they reliable ???
Its very strange that SONY is having in between 2 years a defect.
Its much to early for a real Sony .it was no old refurbished second hand or a forgotten older model ?
Very Important is this is to realize in case of trust was it the intention of the technician to sell you a new t-con or a refurbished one ? thats should in many cases the weak point if you look on that refurbished board that exact the same problem with the same ic could happens then for shure there is a hidden defect. its easy to see where was repaired on the board.
The replace of the lcd panel is maybe guesswork on the fcc cable connection sheets it should only to be replaced if there where vertical lines somewhere
If no warranty is give on hidden defects by the dealer write to Sony A solid complaint.
The dealer is the first contact let them inform a representative of Sony regarding this complaint, the four-year minimum healt of your tv was not reached, you as a customer is entitled to a good product that is expected at least four years. warranty on parts wages in leniency possible but not required.
Questioned about that dealer: are they commercial boxes sliders or solid proffesionals where you just pay and get service without having to smoke a cigar from your own box

Flashing red center light

With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.

My Sony Bravia KLV-32U300A 32 in. HDTV-Ready LCD TV just lost the picture. Just see different colors. Hears static sound from the back of the unit. This was a progression. Few days ago, clicking sound...

hi..It's probably a loose cable. The first one to check is the
green connection but make sure they're all tight. RCA cables
tend to pop out part way which is enough to stop the signal.
If the green signal is lost, you get no picture. If the red or blue
are lost, you get a picture with bad coloring.

If you still have the problem check this
LOOK in the back of the TV when you have it turned on. Look in the slots near the top for a white glow coming out of it.

IF you see it, you need your signal board replaced...

IF NOT, then you need your power supply board replaced...

Dark horizontal lines on Sony KLV-26HG2 LCD TV screen


If you can fix it by yourself, there is a problem in horizontal circuit panel, you need to check that in series because the part appear visbly good but when tested by the exact tester you register busted. that should be replaced immediately. Check also the vertical panel parts of the circuit. but if hard you do the job you may consult the service center of your TV or the vendor of the TV.

ps. please don't rate me if you are not convince of my suggestion.

You probably need to replace the backlight. In parts less than 30$. If you know your way around these things, or know someone who does, it's not a super difficult thing to do. You can get a tutorial that's written for monitors here: basically the same procedure for an LCD TV. Good luck!
