There are not many things that audio and video have in common and the power supply section is most likely at fault.
If the system has an LED indicator and it isn't lit, the supply is probably the reason.

This is not a good place for users to troubleshoot and can be dangerous, even after the power has been off for an hour or two.

    That the LED comes on until the whole set dies, suggests the supply has some outputs temporarily working.

    The fact that the set dies again could very well be a capacitor as 'early' suggested that has failed or lost value, a problem found often in inverter (switching) power supplies.

    This could be a 50 cent part but unless it has blown its case off or at least caused the case to bulge (visible at the top), locating this part requires some knowledge and a meter.

    I don't think the main power cord is at fault.

Please check the connection wire/cable that gives power to your tv. if no fuses are blown. it may be a capacitor problem.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

You have a bad small signal module! Location should be in the rear left side. The board will require extensive work to pull out and reworked or replaced! This board will have three large heatsinks with convergence ICs and an audio ICs attached to them.Good Luck and thanks for asking!

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

You have no high voltage, like many in this forum, this model of Philips has some of the same problems. Look around here you may find the answer to your set. If not check Vertical IC, TDA8177, audio ic on signal board up front on left. check Power supply first for blown fuse, 1000, 2004, 1300, 1900 etc. No sound or pic means something is open. Does set has L E D lights on front of set?

Toshiba 42H83 rear projection tv turns on but i have no picture or sound. happened suddenly. What can troubleshoot before seeking proffessional hel.


Check all micro-fuses in power supply.If two or three are bad,a convergence circuit O/H will be necessary.Pro help usually required-chassis pull,replace convergence IC's and careful hand- soldering needed to prevent call-back.
