It comes on for a few seconds and goes out. Florescent lamps never
light and nothing on the screen. Has the 24 volt to lamp driver boards.
Any hope for this one? Larry @ Centraltv

TV powers on and the LAMP light blinks. There is no picture no sound. This problem arose randomly and out of the blue. Some sources as well as other answers here recommend to replace the lamp, but the lamp glows bright. As well, I removed the lamp from the housing and everything appears to be intact. The blink codes for this unit only indicate that the unit is powering on and will be ready in 15 seconds. Other sources I have read also suggest the digital main board is toast. Seems to be quite a

My Panasonic PT-40LC12 turns on for about 15 seconds with a normal picture and then the lamp shuts off and the fan continues to run. The lamp indicator flashes 4 times. Is it a problem with the lamp or possibly the ballast board
Hi sbr7352,\015\012\015\012Best that you have to test the ballast board for faulty parts, the problem is, this need to checked with an experienced technician because lots of parts in that board involved like the driver transistor, resistors, ca ...

G board Hi. I have a Sony TV KDS-60A3000. The red power led was flashing red 5 blinks. I tried all the basic fixes and nothing worked. I got to the G power board and can see black on the C6501 and R6501 and one other area by the "LAMP DC". I have pictures of the board I can send you also. Thanks :)

I have a hitachi 65SWX20B projection TV. When I power it on, I get no picture, no sound, and on one of the circuit boards, an LED (D967) blinks dimly (1/2 second on, 1/2 second off). A soft click is heard with each on/off transition.
If the board with the blinking LED has larger than average parts on it, it is likely the main power supply and the clicking may be from a relay that is connecting and then, disconnecting the AC.\012With no video or audio, the main power supply has li ...

No picture I replaced the lamp and it worked for 3 months then I lost picture. Pulled it out and saw nothing wrong with it but when I put an ohm meter to the bulb it was an open circuit. I ordered a new one and it lasted 2 hours with the element exploding. Is there something wrong with the TV or are the bulbs junk? They are not from Mitsubishi and the bulbs are not Osram. I have had the TV since 2006 with no other problems. The TV is protected with a Monster surge protector. Any help would be gr

I have searched all over internet and I think you are the only one who may exactly know whats the problem.
I have a Toshiba Regza 37" which has no picture but sounds works perfect.
The thing is if you really focus the picture is there but its too dull and dark to see it properly.
Ive heard something about switching T-Con board.. please let me know which one of the boards is that(any sign or specific connection?)
and where can I buy one?
Thank you very much and best regards
If you can see an image and it's OK - no distortions or corruption - then it's not an image problem, it's a backlighting problem. This means that the faulty part is not the T-con or any other board that works on the image, it's the inverter - the bo ...

I have hitachi t.v. model p50s601 when i turn it on the picture appeares about 1 second imeddietly turns off when it turns off no audio and no picture. already changed the capacitors on the power board c553-c552 = to 3300uf to 100 volts. checked xbus/xsus apperantly no problem. on the power board there is a voltage of vs=88.3v appeares in seconds then imediatly goes to 0. my question is what else can i check? or what could be the problem? thank you for your assistence.
The main rail voltage is not building up and so there is a possibility of a high drain on the output sections. The +B voltage seems to come up and then flatter off as there is a negative feedback to the processor to cut off ...

I have a HLT61765X/XAA. I was watching TV when it suddenly shut off. I tried turning it back on but the lamp faded on and then faded off with one green blinking on the far right (which is lamp, I believe) and one red blinking. I unscrewed the panel and removed the lamp, then put it back in. Now the lamp is lighting up but cannot make it all the way, but stays on. I then hear two buzzing noises every couple of seconds and eventually the lamp light fades away, with both green lights along with the

I have a Samsung DLP HLR5667 and it blew a lamp 4 months ago, I replaced the lamp and it worked fine for about 2 months and started shutting off after only running for about 90 seconds. I reset the lamp hours and it worked fine for another 2 months. Now it is shutting off after 90 seconds of running, first the picture then the audio. All three lights then begin to blink. Troubleshooting I have performed is
1. I have cleaned the interior of the television.
2. Jumpered the lamp door switch.

A lot of these had problems with the lamp door; you need to remove the door and take a careful look at it edgewise---heat from the lamp can warp the door.Notice the small plastic peg on the back of the door--when installed it engages a le ...

I have a Westinghouse television, model #SK-32H540S. When you turn it on both the picture and sound come on (like normal) after about 10 seconds the picture turns off. I had a local television repair company check it out. They told me it needed a new panel. They cannot find one. Do you have a panel or know where I might get one?
I'd appreciate your help.

I own a 50PL9126D/37 50 in DLP TV I bought used and the picture is dark so I took it apart because I was told it could be dusty or could be the lamp. After I cleaned the inside screen VERY carefully with a microfiber cloth I reassembled the set and now the power button or blue doesn't come on nor does the remote work anymore. Plus the TV is still dark, which I figure must be the lamp. I can turn the TV on by plugging it in and hitting one of the side buttons (different one every time) and then u
