Have a RCA Entertainment Series 32" TV (Model F27650). Will not hold power or turn on or off. Green light on power comes on and then shuts off quickly. There is no picture or sound. check all outlets and surge protectors.
There is a slight sound of power, then gone.
Cannot be solved. The TV is a piece of ****. In fact, this should be a learning experience about buying RCA televisions: they are made in china, have no controls over production and are not worth the effort to carry home. Your welcome.
FYI - I took my TV to the local shop. They had it plugged in for 3 weeks and never had the TV turn itself on/off/on/off ever. We brought it home and within 2 days, it was acting up for us again. We had already switched power source outlets a few times troubleshooting the problem ourself. At this point, it appears to be a electrical issue on our end.

Probably not. RCA parts for this model are very difficult to find. Even you could find a kit, it will not have enough to repair. A do it yourselfer or TV tech will have a difficult time repairing this. Please shop for a new TV. Thanks for asking and show a few hands of support!
U DM power supply board have dead capacitors,before the capacitors have some functions left,that why u able to recycles by pushing the power buttons 3 or 4 cycles to get power to the tv.U have tools,soldering iron,solders,and know to do soldering?Tries website like Tvrepairworld.com to buy a capacitors kit,that design to replaced in the DM power supply board.Look around and replaced these dead capacitors,it alway bulges up or puff up on it top.Ur tv will power up and as normal again.
RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again? Please contact me at firstname.lastname@example.org
the high pitch squeal indicates shorted component/s. the transformer goes hot co'z its being overloaded by the shorted component, it too could be the one creating the squeal!!
if you have experience with electronic troubleshooting, try to test some of the components particularly on the secondary part of the transformer. Be careful and make sure the TV set is unplugged. test for shorted diodes and transistors, if you're in doubt of your readings try to desoldering one leg of the diode then proceed with the testing/measuring. replace any of the bad components you find exactly with same part number or replacements with the same rating.
spend more time on it resoldering some other cold soldered components.
This sounds like it could be a malfunction in the High Voltage section of the TV. The shutdown circuit is switching on and preventing the TV from turning on. This might be due to an excessive amount of current flow possibly caused by a shorted turn in the Integrated High Voltage Transformer (IHVT), or a shorted Horizontal Output Transistor (HOT). To test this you will have to unplug the TV set, and with a multimeter set to resistance, measure the resistance from the collector of the HOT to ground, If it reads 0 ohms then that is the problem (a shorted HOT). The next test which is of the IHVT is a little difficult because it requires removing the IHVT and doing a ring test. At this point I would like to suggest that you take the TV to a repair shop, because these next test might be difficult for someone who does not know electronics, and if you have no knowledge of electronics you may do more damage then good.
With that being said:
Remove the HV anode of the IHVT connected to the CRT by first using a large flathead screwdriver connected with a clip lead to the ground of the TV, by sliding the screwdriver under the rubber cap and releasing the clips. Then unsolder the pins on the bottom of the IHVT using a soldering iron and a suction type desoldering pump. when the solder is removed , pull the IHVT from the circuit board. locating the main primary winding connect it to the device that you are using to perform your ring test (I use a Sencore LC-102), when it is connected do the ring test and it should have at least 10 rings to be considered good, any less then 10 and the IHVT is to be considered as bad.
The fault for all of your TVs' is stuck in standby which would point to a fault on the power supply most likely caused by a diode. If you can check this for yourself otherwise find a competant technician. Hope this helps.
The model you listed, F27650 uses the new ATC113 series chassis, which is only about 3 years old. The ATC113 chassis is not known to have snowy issues, but if yours is then I would suspect that a solder joint is loose in the tuner. If your set is actually around 9 years old, then it might perhaps have the notorious CTC175 - CTC187 series chassis, which went snowy all the time due to cracked solder joints on the shield grounds around the tuner and microprocessor. In either case, some good quality resoldering should cure your trouble. If you have never done fine solder work on PC boards with small surface-mount parts, allow a qualified tech to handle it for you.
