Question about Zenith Z27H96R 27" TV

2 Answers

Power Supply? First of all, I am well aware of all the dangers of television repair. Secondly, if I wanted to take it to a shop I would have done so. What I need is highly detailed, step by step instructions and a place to order the part(s). Now, that being said, when I turn on the TV you can here the power "click" on, but there is no power light and the screen stays dark. I suspect it is the power supply. Can the power supply simply be replaced without any re-programming/re-setting of any chip(s)?

Re: Power Supply?

Ok thats great news. Just please dont be alone in the place where you repair this set. So someone can call 911 when you get knocked on your $%$#.. LOL Now that being said and all kidding aside. Zenith TV sets are made for the entire Printed circuit board to be replaced as a whole. Contact and click on technical assistance and then find board by model and enter your model #. If the board doesent come up call them the #s there. You see I cant teach you what parts to replace in an e-mail message. It takes years of practical experience, and the proper equipment to repair an electronic device down to componet level. You will be better off to get the entire board with this Zenith and replace the PC board as it was designed for you to do. Now after you replace this board, there will be a few adjustment you will need to do like screen, focus, as well as modst likly on screen service menu as well, all depense on how well they serviced thios module. They can assist you with this as well. Good luck.

My rca model f36669 makes a popping sound and cuts off and back on

That's hi voltage arcing. Dangerous condition were a component has broken down and is arcing causing the power supply to 'crowbar' or go into over current protection mode. Call a TV repair pro for an estimate to see if you want to keep the set.

Fd trintron won't turn on standby flashes 6 times I have done a hard reset and it worked for a couple of times and is gone again

There are some IC's in the power supply that are going bad. This is a pretty complicated repair. You may want to have a repair shop check it out for you. Thanks

TV has no power after power surge

Probably a blown power supply or fuse in the power supply. I can be fixed but it involves new parts. Most likely you will want to contact the manufacturer or a tv repair shop, unfortunately there is no easy fix for this issue =(.

If you have no power my friend, the problem is not capacitors in the vertical circuit. Your problem is is the main power supply or possibly in the sweep power supply. You will need to first get a service manual for this set and know how to read it. I wish it was that easy as to look and tell you to replace this and to replace that. Yes, some sets do have problems that are common, but this is not the case most of the time. There is voltage inside this set even when it is unplugged, so if you have no TV repair experience, my best advice would be for you to call in a pro to assist you in this repair. Good Luck

No pic, no sound

Power light blinking mean that the internal power supply is not working correctly. Often the internal power supply itself need to be repaired ( usually a one hour work if spare parts available). Another basic circuit in the TV can be short circuited due to a component failure and consequently cause the internal power supply to block everything. A routined pro must be able to tell you within short time cost of repair and spare parts. Up to you to then decide wether or not have this set repaired. Be aware a pro will ask you a fee for this service, even you don't want the set to be repaired.You can save some cost if you bring your TV set yourself to the repair-shop. The kind of problem is not really age-related; if your TV is running daily 16 hours, with many on/off switching, and particularly in a cool place can degrade some components within warranty time.

Sanyo DS31520 went dead

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Squealing noise is from the power supply teling you that there is an overload condiction. The overload is shifting the operational frequency of the power supply into upper audio hearing range. Check the diodes and caps in the supply circuit and the active components in the deflection circuit. also resolder the LOPT, h-output, h-driver, and h-driver transformer. Good luck

Main fuse blows

You may have a surge protector called a thyristor that is shorted right on the main a/c line. Or the main power supply has a major nasty short as the bridge rectifier the filter cap or the degusing coil.
