Samsung LNT1953H T.V

It's not the lamp, most of the time they suspected it and the fan gone to malfunction when encountered this kind of symptoms but the fault came from the color wheel. You have to replaced it to resolve the issue.

I have a Philips 60" Rear Projection, and all of a sudden I have no picture or sound. I push the power button, and all it does is click. It will keep clicking until I turn it off. Anyone seen this problem?

Tv has no picture or sound; will go out while watching. The picture will go into a line and sound and picture will go out; shortly after that tv will turn off. Did this last nite and I did not turn back on until this morning, it worked no problem. On for couple of hours and now it's out again. What could be problem and how do I fix myself

I would check out the power supply module for bad caps with bulging tops. Check DC voltages at the output connectors, you should have 5, 12, 24V.

it may be a bad DMD board. This is usually the problem when you get the three lights of death.

1. Can you view a DVD correctly? Good video and sound?
2. If so, you can get an "external tuner" like the Digital convertor boxes that the government subsidized and hook that up to your cable....
It will work (if you answered YES to #1)

3. Cost to fix TV is around $120... (tuner board)
(Don't open TV ... high voltages in there...)
4. Cost to use an external tuner around $20
5. Cost to use only for viewing DVD's ... FREE

Hope this helps.

Try replacing the ballast next. Its the small circuit board directly underneath the lamp housing. You can access it through the lamp door. If the ballast is overheating or has a leaking capacitor, the tv won't stay lit for more than a minute or two.

Hello arunaik_6,

This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.

I hope this helps,

Thank you,

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

Its Sounds like Convergence Circuit,If you take the Back off and look on the right side you should see a Board with Big black Ics Mounted beside a Large Heatsink,Mark the wires where they go and Make sure the POWER is Off Pull the Board out and Inspect the Connections from the ICS,you find Circle Breaks,They need to Be resoldered and That should fix the Set....
