Question about RCA 27V520T 27" TV
We purchased this TV on clearance at Walmart's no booklets and no warranty... The TV was working fine when we went to bed last night and this morning all we get is a sound and no piture... It did this yesterday morning so we turned it back off and then on again and it worked fine... But this morning turning it off then back on doesn't help .... Any suggestions?

Hehehe Its all in a matter of taste I like sony and Mitsubishi. You like RCA you get what you pay for. These sets are good for the L401 in the horizontal drive circuit to cause your problem as well as a blown fuse and a shorted horizontal output trasistor and the flyback transformer. if its anything Im thinking off the repair cannot be done by a handi person and should be taken to a pro and will cost in the range of150 to 225.00 for this repair. good Luck

What you are hearing is the discharge of high voltage which if it hasn't already failed, will fail if allowed to repeat too often.
The only thing you might try after unplugging the set for a minimum of 24 hours, is to remove the back shell (shouldn't be more than 8-10 screws around the perimeter and perhaps one or two around the connector cutout) and with a clean paintbrush and a vacuum cleaner with the nozzle held close to the work area, brush the CRT (picture tube) free as possible of accumulated dust, paying particular attention to the area around the large rubber cap with a cable leading to the circuit board.
I can't stress enough that the set must be ignored to allow the 25,000 plus volts that are present on the CRT when operating are given a chance to 'bleed off.' This voltage doesn't often kill anyone since it is a short-term discharge with the set off but I have seen it punch a hole through a thumb.
If you are lucky, the horizontal circuit is not in its death throes but only discharging through a layer of typical household crud. Unfortunately, this will not likely help you and you will require a tech to locate the problem. Good luck finding one that isn't dead or retired yet; we are dwindling.

This has happened to me quite frequently. I have replaced the fuse at least 8 times. You just take off the back of the t.v. and on the bottom you will see a small glass fuse. just pop it out and go to radio shack and get a pack of replacements. about 4 for 3 dollars.

SOURCE: TV turns on and off by itself
My RCA set just started recently doing the on/off issue too so, I decided to look on line and found many of you having the same syptoms. What I was experiencing was, no matter what button was pushed, it would turn off/on and also turn off/on by itself. I decided this past weekend I would take the back cover off mine, use compressed air with an air nozzle and blow the dust from every area I could. I particularly concentrated on the front control panel strip. I blew into the tact switches the best I could while I had it removed from where it is held in by two screws. Turned the set back on and realized they worked again. I was thrilled! Maybe this is a solution for some of you out there. It's worth a try.
