If what your saying is that there are vertical stripes down the screen, You have a screen drive problem my friend. This could mean you will need to change the entire main board, the screen driver board if it is separate on this set, or the main LCD panel itself. These boards do not have any parts available for them and must be replace as a whole unit. Good Luck

Sounds like a lamp error.... either a defective or broken lamp within the LCD1.gif panel itself, or you have a bad inverter.

No, the voltages are just fine. The fault must be either in the PMW itself or in the HT transformer - and the only way to fix that is to replace the entire inverter board.

Power light is on but no picture


you did not mentioned if you have raster or none, if your tv has raster but no picture your problem is in your I.F. section and your tuner, now if no raster, you can check your power supply, check your 5volts, 9volts, and 12volts check any alternatives that cause of no picture..

Signal Problem


Hi,

When the sound is working and the picture is not it indicates the main power supplies are working but the picture supply is not. The picture supply that powers the projection tubes is a high voltage generator and is very expensive to repair. Not even most tv techs now how to troubleshoot them. So, I cannot recommend you repair it yourself unless you are a trained high voltage tech.

The cost of repair - my wild guess - would be around $300. However, the real cost can only be determined by someone who can make an accurate diagnosis - which will require a hands-on approach the problem.

If you have any other problem please ask me..
Goodluck,

Jvc tv model av dx25,power on but no raster and sound


if you want to do it with your own, you will need a proper trouble shooting. which need the right device and tools to do the job and make sure you have at least a basic knowledge in electronic repair. the first place to be check will be the power supply section, you need to have voltage checking weather their is a secondary dc voltage from the power supply section going to the horizontal section. to turn on the other circuit and the flyback transformer. you have to know if their is a 135dc voltage at the power supply section,check at the primary capacitor using a digital tester.

Sony projection tv 48inch year model 1997. we have only sound no picture.?


Your have problem in the power supply, since there is sound meaning the other section were working. Your Raster is missing or the horizontal and the vertical or your dont have high voltage to run the tube screen. Either the problem would be open Fuse or open resistor on the power supply or the Horizontal output stage damage.

Hitachi projection tv has no picture but has sound


hi.. if your projection TV has no raster at all, it has problem with high voltage supply. there are two separate power supply inside your TV for audio and for the high voltage for 3 CRT tubes.its very dangerous to service it by yourself.

It looks like our Samsung LA32B450C4 needs hopefully only a new fuse. It's not readable anymore, so I don't want to buy the wrong fuse. No power but plugged in!


Can buy fuses it at any Radio Shack stores.The fuse it at the end of the power supply board.That the board,where the power a/c cord plug into it.Modern electronic equipments have very small chances the fuses dies in the normal operating situation of the devices.Tv have the power supply board problems.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Green light comes on no picmor sound


Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

Picture does not bleed to edge


this symptom is caused by a poor regulation in the power supply circuit. too low dc supply voltage will result to insufficient deflection, both vertically and horizontally. black borders appear around the raster. receivers generally use regulator in the main power supply to set the dc supply voltage at the value that will allow the picture to fill the screen with a little overscan. defective regulator can result in a small raster. most modern receivers today are using ic (integrated cirduit) regulator. but if you are not inclined with this kind of job, better bring it to a qualified tv technician. good luck!
