Samsung Projection TV

Purchased TV in 2003. TV would turn off by itself everyonce in awhile. All I had to do was turn it back on. Now TV won't stay turned on. Any suggestions?

Try unplugging the 3 wire plugs for the convergence yokes and try powering up the set. if it comes on you will need convergence ICs if it doesnt you will need a deflection board. let me know what you discover as I can help you with either problem

Turned itself off. I turned it back on and the green power light blinks for awhile then blinks red for awhile.no picture or sound


Get rid of this TV. Had one and replaced the bulb and light engine many times. Just buy a Samsung or Vizio 50+ inch instead and be very happy. Those Panasonic projection TV's were terrible. You will find a 50 inch Vizio for around $500 bucks and it will blow your mind how great the picture looks.

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

Sony kf-50XBR800 tv turns itself on and off


I just purchased a replacement lamp off ebay and the TV is working fine now. Color looks better too (which I guess I should have expected). Search for "REPLACEMENT LAMP SONY XL-2100U" on eBay and look for seller "niosales". I paid $129 out the door. Their are other auctions for this lamp you can check out. Make sure you look at lamps that include the entire lamp housing, not just the bulb.

Mitsubishi WS48511 TV will not power on completely.


have you checked the pico fuses on the bottom side of the PC board? They are small ceramic fuses soldered directly to the runners.They have been known to blow and your set will not power up. Hope this helps, if you need anything further let me know. Also sometimes the 1000uf caps don't show any signs of swelling but can still be bad.
