I have an RCA 32LA30RQD 32" LCD HDTV DVD combo. Everything works...i hsve sound and the dvd plays but i have no picture...there was a circuit interruption and when i turned everything back on i had...

Hi well unfortunately this could be almost anything in fact, what you need to do is to obtain a service manual for your exact make and model, in there are the troubleshooting procedures to follow to isolate and hopefully repair this unit. The SM maybe able to be obtained from a Google search using the exact make and model, that or a direct approach to the manufacturer may yield a manual? Successful repair is almost impossible without such a manual, if only to order spares?.
The " circuit interruption" (sic) was indeed most likely the cause, what has most likely happened is that the Inrush current damaged something when power was restored.
In a this have most likely been damaged in the Power Supply section, and in any event this is the first place to start, one must always first check the PSU, as if the PSU isn't 100% then NOTHING else can be. There are NO shortcuts, indeed that, taking shortcuts, is the best way I know of to ruin any chance of repair for anyone now or to come. It is simply? a matter of testing the PSU and working out along any "Bad Rails" the Voltages here are critical and always will lead us to our problem, if the Voltages are too High, we are looking for some sort of Open Circuit, usually a component failed in the open circuit position, now if the Voltages are too low, then we are looking for a Full or Partial Short Circuit type of thing. The service Manual is essential in troubleshooting and understanding the entire thing. Further the SM allows one to know the parts Numbers required to order spare parts for replacement. usually Board level component isn't too realistic and mostly the entire faulty board is replaced, when suspect.
However if DIY is not an option, then in my humble professional opinion, the very best thing to do to get it actually repaired, and at a reasonable cost, is to contact a local or head office from RCA, then ask them for a referral to an authorised service center, now when in touch here and when in face to face contact, well, at this time, ONLY ask first, for a "Quote", as to the costings of the prospective repair, then armed with this information one can make up ones mind as to repair or replace.

I have a Toshiba 42inch LCD TV, model # 42LX196 that is just a little over a year old. The picture went out suddenly, and would only come back after unplugging and re-plugging in the TV. This happened...

I think you should call Toshiba and ask them for assistance. I am no expert on TV's, but i think that would be your best bet on how to repair and found out what happened to your TV. Call them at 1-800-631-3811. Hope this helps. :)

If all the voltages measure normal, the failure could be in the LCD's inverter board. I've checked the schematic and it seems like the 16 volts could be a bit higher, check the electrolytic capacitors filtering the voltage for the inverter board.

Good Luck.

Sound but no picture

Is this an LCD set? if so...

Try the set with the inverter unplugged and if you get sound its almost certainly the inverter. You might also see a very dark picture as the screen will be working but the backlight wont be lit.

Be very carefull with the inverter, theres some high voltages there.

If its not LCD I think we would need to know the model.

Hi! name's wesley. anyways, here's the problem. i just bought a new samsung 32' lcd tv and everything is great except for one thing: when i connect my ps2 to the "av 2" input, the sound comes out...

There is a problem with the AV2 input. Since this is a new set, return it for repair or exchange. DO NOT open it up as that would void the warranty.
