I have a sylvania 32in replacement tv circuit board model srt2232s It doesn't turn on anymore , fuse is good , buzzing coming from a transistor I think any thoughts . Thanks


Hi there, sorry to hear. That "buzzing" you hear is most likely that power supply onboard, pulsing in a failure mode such as a current limit situation. Check for shorted rectifiers, and the common bad capacitors.

If you know fuses are bad you would have to have already found "a couple"


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_26_2012_2_28_29_pm.jpg5_26_2012_2_38_39_pm.jpg

Proton pltv3250 no video but has sound


now you need to check the inverter pcb , sometimes there is bad capacitor , also make sure there 24 v coming from the power supply , if you have 24v caming from power pcb going to the inverter pcb most like open fuse on the inverter pcb

My protron tv went off and won't come on pltv


Hi, most protons have power supply problems, the power supply is no longer available, but it can either be mailed in to a company called PTS to be rebuilt or you can attempt a component level repair yourself.
Most non technical people can not disassemble and solder there TV.
If you are comfortable soldering, you can open the TV and view the power supply (upper center section) look for any bulging capacitors (cylinder looking small components) sometimes replacing the swollen caps will fix your Proton, If any parts look burnt you will need to send the board to PTS to get it rebuilt , should cost around $100.
PTScorp.com can be found online here or bring the TV to a local servicer that agrees on a flat rate price to fix it
thanks'

Philips 42PF7220A/37B won't turn on at all. No green or red lights come on. This happened after we had a storm and the electric just went out. Any ideas?


Most likely it's a power supply board related issue. It maybe something simple like a blown fuse on the board. The fuse replaceable. Radio Shack or Electronic supply place will carry replacement fuses.
The other possibility is the power supply board itself is damaged. It maybe a bad capacitor or a transformer on the board. Replacement boards can be found on the internet. A good place the start is Shopjimmy.com.

No power out from power board fuse blowing


if you own a FLAT PANEL and POWER SUPPLY section keeps blowing the fuse , check the voltage regulator ( IC ) AND CAPACITORS , beware that most of the manufacturers have control of their own parts , meaning that you ll end up buying the POWER SUPPLY SECTION, Good luck , AJ

I have a Flat screen TV Proton 42'' only 1 year 1/2 old


Protron PLTV 4250- wont turn on-
Had the same problem with one here- The 110v end of the power supply board was found damaged, The following items may need to be replaced:
Fuse F1 (soldered in) . 6.5a @250v time delay
Mouser 576- 021506.3HXP – note this style is for a fuse holder instead of solder in- I added a fuse holder on the board
RT4 & RT5 inrush surge suppressors - I used shintron 8d-18 power suppressing thermistors
BD1 bridge rectifier - Mouser 627-D15 XB 60H Shindengen

If you want a little more protection modify the board as follows:

1.replace only RT5 in its original location & move RT4 into the other ac input line in front of the bridge rectifier. (cut trace & drill solder holes)

2. Add: MOV (metal oxide varistor) across ac inputs of bridge rectifier.
Maida mdc-z481-8oul or D69 ZOV 481 RA 105
This arrangment is copied from a samsung power supply.

Be careful when plugging in the I/O box on the outside cover, if any pins are inadvertantly bend loss of picture will result.

I have pics if anyone needs them .
