    Norcal715 doesn't recommend LCD TVs

    Jump to 4:48 mark and watch until 6:50 if you are short on time.

    Norcal715 doesn't recommend LCD TVs due to bad tab bonds as he sees 2/week (I have a Toshiba 46 inch TV with one).

    He used foam to fix this one, but he can't guarantee the repair (or charge the customer).

    Interesting. I generally don't like to work on LCD TVs. The last few I've repaired (or attempted to repair) had main board issues or panel issues, so I had to buy the main board or have it repaired, or I had to junk the TV.

      Pretty hard to condemn a single platform whether it be LCD or PLASMA. Both seem to have their share of issues for reliability.

      One thing I think is wrong is the fact that the manufacturers don't like extending past the standard warranties. Too easy to develop a product and walk away from it when there's a clear pattern of failures.

      They brought out new legislation here that basically states that the manufacturer still has an obligation to fix it if not fit for the purpose which takes into account what a reasonable lifespan for the product should be.

      Premature panel failure I would consider something I'd take them up on.

      Personally I like Plasmas for repair.

        My definition of repair, and probably most of the regulars here, is troubleshooting and replacing down to the component level.

        Some people report they "repaired" something by board swapping.

        Anyway, both LCD and plasma have their problems. I usually never buy extended warranties, but Costco has reasonable prices to extend the warranty up to 5 years.

        As for me, I don't have the space, muscle, vehicle or motivation to repair TVs for fun or money. If I had to work on a TV, I prefer LCDs as they are generally very similar to computer LCD monitors which I have repaired a lot of.

        PS. I don't count using furniture tabs holding down the tab bonds on my Toshiba as a "repair". It is more of a hack.

          I'm hearing you loud and clear. sadly we're board jockeys, probably why i challenged myself to get down and dirty with a couple of SC boards. having 3 dead ones seemed rediculous so now I have 2 of those working spares and only test gear i have is my trusty Fluke 77.

          It's a great challenge, should be more of it although sometimes a secondhand board can be so cheap it just makes sense to do a swap.

            As far as tab bond repairs go, I've done one successfully and a friend has done two. They seem fairly common but I'm never 100% on whether they will last.

            Most plasma and LCD faults I've found to be quite repairable but the proportion of failing main boards due to corrupt firmware is ever increasing.

            Class action lawsuits are a joke. The lawyers make the most money from it. Rather, I believe it would be best if there was some kind of minimum enforced 5 year warranty with every product, with an emphasis on repair rather than replacement.

                  Plasma is a better technology than LCD for TV, it's a shame that most people buy LCDs. I can't blame them though. Maybe they have the problems with the LCD panels (To be fair, he had a Chi Mei panel there - not exactly top notch), but people will never get the massive plasma graveyard. The technology has vastly improved since then, Panasonics latest sets are excellent I hear.

                  LCDs are better as computer monitors because the computer monitor sizes (Up to 27") have a much higher pixel density.
                  "We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

                    I wouldn't want a plasma for a computer monitor. There is a great risk of burn in, but the problem is more due to them being so bright (high contrast ratio) -- it's quite uncomfortable to look at. I love plasma for TV though, but for a bedroom TV I will use an LCD TV because that makes sense. (Picture quality isn't a big deal on a 32"/37" LCD, and it's nice to use less power.)

                      Another reason why I avoid board swapping is that I cannot get reasonable shipping prices to Canada. Often the shipping costs are more than the board and when you combine the two, it is not economically feasible to repair.

                      For people in the USA, you have much lower shipping internal costs.

                        not too bad importing in but AUSPOST out is rediculous. UK can be ok too. Sometimes i just have to wait for a bargain to pop up.
